Feature Request - MapKit JS: Add "above roads or labels" OverlayLevel to TileOverlay
The MapKit Framework for Swift lets a developer control where a raster/tile overlay is drawn relative to other map content using MKOverlayLevel (.aboveRoads | .aboveLabels) passed to MKMapView.addOverlay(). MapKit JS has no equivalent. There is no level parameter to say "draw this above roads" or "draw this above labels." Please add an overlay-level option to MapKit JS 1️⃣ MapKit JS with TileOverlay Opacity=1 An opacity slider is implemented to help the map viewer to orient themselves with the MapKit JS Hybrid style with a sample raster TileOverlay. 2️⃣ MapKit JS with opacity via slider 3️⃣ MapKit for Swift demonstrates the options for above roads or labels

Opening Hours for Map Routing
I'm looking to access Apple Maps place metadata, particularly opening hours to route a user between 3 points. Suppose point C opens in the morning and B in the evening, I'd make sure to route the user based on which place is open at the time, eg A => C => B I understand from this thread that opening hours is not something app integrations can export. I was also checking out the batch endpoint. While its not necessary to export the data or display it inline, I'm looking for ways that my app can consume or consider this when routing between multiple places.

Maps tokens suddenly stopped working today and now return 401 everywhere
Hi, Our Apple Maps integration has been working normally for years, but starting today, newly created Maps tokens suddenly became unusable. Tokens created from the Apple Developer backend now return 401 Unauthorized everywhere we test them. We can reproduce this in: our own code Apple’s Try Maps Server API page MapKit JS So this does not appear to be limited to our app code. We also tested through a US network entry point to rule out a mainland China network issue, but the result was the same. At the moment, Maps tokens created in the backend seem to be unusable in all cases on our side. Has anyone else seen this today, or is there any known issue affecting Maps token creation or validation? Thanks.

MapKit JS is not available for use within mainland China. The browser console shows a 401 error for the API.
I am using the code provided on the website https://developer.apple.com/maps/sample-code/embedded-map/index.html, replacing it with my own MapKit JS Token. When accessing it using a network in mainland China, a 401 error occurs with the message [Initialization failed because the authorization token is invalid]. However, it works normally when using a network in Japan. Does this service not work in mainland China?

Handle Apple Maps Legal information in a kiosk environment
We are currently building a kiosk system that displays an indoor map built using the Apple Maps Toolkit and have encountered a challenge regarding the required link to the Apple legal information page. In a standard web application this is straightforward, but in our kiosk environment following the link opens a new webpage and effectively takes users out of the map application, which disrupts the kiosk experience. Our preferred approach would be to intercept the link and display the legal information in a modal window within the application. However, we've not yet found a way to make this possible. Has Apple got any recommended approach or best practice for handling the mandatory legal link in kiosk deployments? Has anyone seen other kiosk implementations address this requirement in a supported way? Thanks for the support!

MapKit JS quota limit architecture decision
Hello, I have a question similar to this post regarding MapKit JS quota limits. I understand that we can request rate limit increases, but it is not a guaranteed increase. My app is rapidly growing. What if Apple decides to not award the limit increase? Then, the directions service of my app will stop working, which would be catastrophic for my company. I need to know if the rate limit increases are guaranteed. I need to decide early on whether to use MapKit JS or another service on, because the more time that passes, the more entangled my code will get with MapKit JS. Can we get some more information on this?

MapKit JS quota limits
Hello, I’m planning to use MapKit JS for a production web/mobile application and I’m trying to better understand the quota limits and pricing model. From the documentation, I understand that MapKit JS provides a free daily limit of: 250,000 map views 25,000 service calls per Apple Developer Program membership. However, I’m not clear about what exactly happens if these limits are exceeded. My questions: If my application exceeds 250,000 map views or 25,000 service calls in a day, what happens? Will the API simply start returning errors (for example HTTP 429), or will Apple automatically charge for additional usage? Is there an official pricing model for usage above the free quota, or do we need to contact Apple to request higher limits? Are these limits strict daily hard limits that should never be exceeded in production? I’m trying to design the architecture of my application and would like to understand whether we must strictly stay below these limits or whether scaling beyond them is possible. Thank you.

MapKit JS Look Around not pointing camera towards the lat/lng entered
We are using MapKit JS Look Around and initializing it like this: window.lookAround = new mapkit.LookAround( document.getElementById('container'), new mapkit.Coordinate(listingLocation[1], listingLocation[0]), {openDialog: false}) ; This results in a Look Around scene being displayed correctly but the camera heading is not pointing towards the lat/lng that is passed to initialization. The example lat/lng that we're using is: lat=30.004195, lng=-95.59973 This lat/lng corresponds to the address: 11943 Laurel Meadow Dr, Tomball, TX 77377. The camera is pointing to the other side of the street to house number 11946. If you look for that address in Apple Maps the Look Around points to the correct house. Is there a way to either specify the heading so that Look Around points in the correct heading? Sample link: https://s.hartech.io/zFP2KnsCbsP

MapKit Snapshot API returning blank dark blue images — started today
Issue: MapKit Snapshot API returning blank dark blue images instead of satellite tiles as of March 4, 2026. This is affecting production and we need urgent assistance. Endpoint: snapshot.apple-mapkit.com/api/v1/snapshot Symptoms: HTTP 200 response with a valid image file, but image is a solid dark navy frame with only the Apple Maps watermark — no satellite data. Occasionally a correct satellite image is returned, but the vast majority are blank. Parameters: t=satellite, 640x640. Confirmed not caused by code changes (none made), auth errors or rate limiting (status is 200), or an invalid image format (image is well-formed, just blank). API keys have been rotated and the issue persists. The intermittent correct responses suggest a backend tile-serving issue on Apple's side rather than anything client-related. Started: March 4, 2026. Same requests that worked prior to this date now consistently fail. Please see the attached sample images for reference. ASAP resolution is appreciated as this is actively impacting production. Thanks, Tristan

Disable userLocationAnnotation bubble
Hello, thanks for your effort! I found that when showsUserLocation is set to true (by default), the pulsing blue dot user location annotation is shown, which is cool and beautiful. However, it will automatically and periodically attempt to call the Apple Server API GET https://api.apple-mapkit.com/v1/reverseGeocode within userLocationDidChange() and updateUserLocationAnnotation() to display, I assume, the user's current address when single-tapping on the blue dot. It will significantly use the MapKit service calls quota since the user location is automatically updated. It almost runs out of quota even though the map initialization is plenty enough. Is there any way to disable the bubble behavior but preserve the user location blue dot, which is lovely and better than drawing my own user location dot? It seems I can only turn off all user location features. Many thanks!

Z-Index for MarkerAnnotation
Hey there, is there a way to set the z-index for MarkerAnnotations in MapkitJS? I'm loading up to 200 markers dynamically as the map moves or the user zooms and I want a few specific markers to always be at the top (the best search results). The only way I found is to always remove all markers and then add them again in the right order, but that's visually so annoying to see them disappear and animate in with every tiny movement. I thought about using a default Annotation and setting the z-index myself and trying to rebuild the balloon, including the animation when it's clicked, but the big downside is probably the performance because I won't be able to use shadow DOM elements and have 200 real DOM elements instead. Is there a solution to this right now or is it planned to add a feature like that to Mapkit JS? It's a real blocker for me right now because all the bad content always gets rendered on top when a user zooms in, because I obviously want to show the best content first when the user isn't zoomed in yet. Thank you so much in advance. I really appreciate it. Manuel

DataCloneError in MapKit JS Worker when posting non-detachable ArrayBuffers (Chrome ≥120)
Since integrating MapKit JS, we’ve begun receiving production error reports with the following message: Uncaught DataCloneError: Failed to execute 'postMessage' on 'DedicatedWorkerGlobalScope': ArrayBuffer is not detachable and could not be cloned. It appears that MapKit JS’s internal worker occasionally calls postMessage() with an ArrayBuffer that cannot be detached under Chrome 120+. This causes the structured clone to fail and the error surfaces uncaught from within the worker. MapKit JS Version: 5.79.109 Browser: Chrome 120.0+ OS: Windows 10 Is this a known issue with MapKit JS? If so, are there recommended workarounds or planned fixes?

Questions about Maps Server API / MapKit JS quotas, temporary caching (including sessionStorage), and commercial website usage
Hi, I’m a member of the Apple Developer Program and I’m planning to use Apple Maps Server API together with MapKit JS for a production, customer-facing web service. I have reviewed the Apple Developer Program License Agreement (including Schedule 6 – Apple Maps Services) and the documentation, but I still need clarification on several points to ensure that our usage fully complies with Apple’s policies. Daily quota and additional capacity From the documentation, I understand that there is a daily limit of 250,000 map views and 25,000 service calls per Apple Developer Program membership, shared between MapKit JS and Apple Maps Server API. When the 25,000 service calls are exceeded, the API returns HTTP 429. Should this limit be considered a hard limit for production use? The wording “For additional capacity needs, contact us” is unclear. Is there any official channel or program to request a higher quota, or should we assume this is not practically available and design our system to always stay within the documented limit? Caching of geocoding / reverse-geocoding results Schedule 6 section 2.5 restricts caching, prefetching, or storing map data except when temporary and only as necessary for Apple Maps Services, and any cached data must be deleted after use. To understand what “temporary” means in practice, I would like to confirm whether the following scenarios are acceptable: (a) In-memory cache during a single page or tab session: - Store geocoding results (latitude/longitude and normalized address) only in a JavaScript in-memory structure (e.g., a Map object) during the lifetime of the browser tab. - Delete all cached results when the tab is closed or after a short TTL (for example, a few minutes). (b) sessionStorage with a short TTL: - Store geocoding results in window.sessionStorage on a per-tab basis. - Apply a short TTL (for example, a few minutes), and delete the data when the TTL expires or the tab is closed. Are both (a) and (b) considered acceptable forms of “temporary caching” under section 2.5, or should we avoid sessionStorage and limit ourselves to purely in-memory (non-persistent) caching? Use on a commercial customer-facing website Our intended use case is a public website that: Displays store locations on a map Allows users to search for nearby stores Optionally shows routing directions We do not do fleet management, asset tracking, enterprise route optimization, or insurance risk scoring. Is this type of consumer-facing store-locator use case permitted under the Apple Maps Services terms? Any clarification from the Maps or MapKit teams would be greatly appreciated. Thank you. Best regards, Naoto Omori

MapKit JS authorization token invalid for Chinese network
Hello 👋🏼, We are using MapKit JS to display maps on our application working on two domains .com and .cn. Everything is working for all ours users in the world except for users using Chinese local network. After investigation, there is an error display in the browser console: [MapKit] Initialization failed because the authorization token is invalid. As the tokens are used as they are for the rest of the world, we know that they are valid... 😕 Problem appears on all browsers: Current versions of MapKit JS mapkit-typescript @ 5.18.2 https://cdn.apple-mapkit.com/mk/5.49.x/mapkit.js Do you have any tips, suggestions to help us 🙏 ?

Request for Higher MapKit Service/API Quota
Hello Apple Developer Team, I’m currently using Apple MapKit JS as the main map provider for our logistics, telematics, and HR platform TADMIN, and we are extremely satisfied with its reliability, accuracy, and visual quality. We would now like to expand our Apple integration by migrating our backend reverse geolocation services to Apple as well. However, our current usage requirements significantly exceed the standard 25,000 daily service request limit. At this stage, we already need between 250,000 and 350,000 reverse geocoding requests per day, and this number will continue to grow rapidly. Our TADMIN Tracking product processes live GPS data from connected vehicle telematics boxes, and each vehicle sends an average of 1.5 pings per minute in normal mode. We currently manage around 140 vehicles and are already in discussions with new customers that will add over 1,000 additional vehicles to the platform soon. As our customer base continues to expand, we expect this growth trend to accelerate significantly over the coming months. We already make extensive use of caching to minimize redundant geolocation calls. For example, we reuse location data when vehicles remain within a defined radius. However, since trucks rarely stay stationary for long, there is still a constant flow of new coordinates that require reverse geolocation. To give you a broader picture: TADMIN is a comprehensive SaaS ecosystem for the transport and logistics industry, combining HR management, telematics and tracking, dispatching, and data analysis into one integrated platform. The Tracking module is just one part of this system and serves as the live data backbone for our dispatching, HR, and telematics analytics modules. We would therefore like to increase our quotas for: Service Requests (especially Reverse Geocoding) Snapshot Requests, which we use for our Geofence Alerts. These are sent via push notification and email, and we would love to include the snapshot images in the emails for a clear and visually rich presentation MapKit JS Views, since we also use MapKit JS heavily in our web dashboards, for example in our tracking portal Higher quotas would allow us to rely even more on Apple services, including Autocomplete and Geocoding for customer-facing address searches inside our applications. We already have three apps published on the App Store, with a fourth one scheduled for release this week, and I will soon be upgrading my Apple Developer account to an Organization Account for our company. We are currently evaluating providers for this next stage of integration, as we are preparing a new major version of our TADMIN software, which will introduce a reworked telematics backend. Our goal is to migrate to Apple’s geolocation and map services as part of this new release. Could you please advise how we can best address this use case, for example through higher quotas or an adjusted configuration? Thank you very much for your time and support. Best regards, Timo Köhler Founder & CTO, TADMIN GmbH

Questions about Maps Server API / MapKit JS quotas, temporary caching (including sessionStorage), and commercial website usage
Hi, I’m a member of the Apple Developer Program and I’m planning to use Apple Maps Server API together with MapKit JS for a production, customer-facing web service. I have reviewed the Apple Developer Program License Agreement (including Schedule 6 – Apple Maps Services) and the documentation, but I still need clarification on several points to ensure that our usage fully complies with Apple’s policies. Daily quota and additional capacity From the documentation, I understand that there is a daily limit of 250,000 map views and 25,000 service calls per Apple Developer Program membership, shared between MapKit JS and Apple Maps Server API. When the 25,000 service calls are exceeded, the API returns HTTP 429. Should this limit be considered a hard limit for production use? The wording “For additional capacity needs, contact us” is unclear. Is there any official channel or program to request a higher quota, or should we assume this is not practically available and design our system to always stay within the documented limit? Caching of geocoding / reverse-geocoding results Schedule 6 section 2.5 restricts caching, prefetching, or storing map data except when temporary and only as necessary for Apple Maps Services, and any cached data must be deleted after use. To understand what “temporary” means in practice, I would like to confirm whether the following scenarios are acceptable: (a) In-memory cache during a single page or tab session: - Store geocoding results (latitude/longitude and normalized address) only in a JavaScript in-memory structure (e.g., a Map object) during the lifetime of the browser tab. - Delete all cached results when the tab is closed or after a short TTL (for example, a few minutes). (b) sessionStorage with a short TTL: - Store geocoding results in window.sessionStorage on a per-tab basis. - Apply a short TTL (for example, a few minutes), and delete the data when the TTL expires or the tab is closed. Are both (a) and (b) considered acceptable forms of “temporary caching” under section 2.5, or should we avoid sessionStorage and limit ourselves to purely in-memory (non-persistent) caching? Use on a commercial customer-facing website Our intended use case is a public website that: Displays store locations on a map Allows users to search for nearby stores Optionally shows routing directions We do not do fleet management, asset tracking, enterprise route optimization, or insurance risk scoring. Is this type of consumer-facing store-locator use case permitted under the Apple Maps Services terms? Any clarification from the Maps or MapKit teams would be greatly appreciated. Thank you. Best regards, Naoto Omori

MapKit JS authorization token invalid for Chinese network
Hello 👋🏼, We are using MapKit JS to display maps on our application working on two domains .com and .cn. Everything is working for all ours users in the world except for users using Chinese local network. After investigation, there is an error display in the browser console: [MapKit] Initialization failed because the authorization token is invalid. As the tokens are used as they are for the rest of the world, we know that they are valid... 😕 Problem appears on all browsers: Current versions of MapKit JS mapkit-typescript @ 5.18.2 https://cdn.apple-mapkit.com/mk/5.49.x/mapkit.js Do you have any tips, suggestions to help us 🙏 ? Aurélien.

Request for Higher MapKit Service/API Quota
Hello Apple Developer Team, I’m currently using Apple MapKit JS as the main map provider for our logistics, telematics, and HR platform TADMIN, and we are extremely satisfied with its reliability, accuracy, and visual quality. We would now like to expand our Apple integration by migrating our backend reverse geolocation services to Apple as well. However, our current usage requirements significantly exceed the standard 25,000 daily service request limit. At this stage, we already need between 250,000 and 350,000 reverse geocoding requests per day, and this number will continue to grow rapidly. Our TADMIN Tracking product processes live GPS data from connected vehicle telematics boxes, and each vehicle sends an average of 1.5 pings per minute in normal mode. We currently manage around 140 vehicles and are already in discussions with new customers that will add over 1,000 additional vehicles to the platform soon. As our customer base continues to expand, we expect this growth trend to accelerate significantly over the coming months. We already make extensive use of caching to minimize redundant geolocation calls. For example, we reuse location data when vehicles remain within a defined radius. However, since trucks rarely stay stationary for long, there is still a constant flow of new coordinates that require reverse geolocation. To give you a broader picture: TADMIN is a comprehensive SaaS ecosystem for the transport and logistics industry, combining HR management, telematics and tracking, dispatching, and data analysis into one integrated platform. The Tracking module is just one part of this system and serves as the live data backbone for our dispatching, HR, and telematics analytics modules. We would therefore like to increase our quotas for: Service Requests (especially Reverse Geocoding) Snapshot Requests, which we use for our Geofence Alerts. These are sent via push notification and email, and we would love to include the snapshot images in the emails for a clear and visually rich presentation MapKit JS Views, since we also use MapKit JS heavily in our web dashboards, for example in our tracking portal Higher quotas would allow us to rely even more on Apple services, including Autocomplete and Geocoding for customer-facing address searches inside our applications. We already have three apps published on the App Store, with a fourth one scheduled for release this week, and I will soon be upgrading my Apple Developer account to an Organization Account for our company. We are currently evaluating providers for this next stage of integration, as we are preparing a new major version of our TADMIN software, which will introduce a reworked telematics backend. Our goal is to migrate to Apple’s geolocation and map services as part of this new release. Could you please advise how we can best address this use case, for example through higher quotas or an adjusted configuration? Thank you very much for your time and support. Best regards, Timo Köhler Founder & CTO, TADMIN GmbH
