Endpoint
The endpoint for the notifications can have any path desired. It's a POST request sending JSON. HTTPS is required. There is no authentication. Events are sent as signed JWTs using the OIDC JWS keys for verification.Body
The body is a simple json structure:
Code Block { "payload": "<event Token>" }
Event Token Structure
Code Block { "iss": "https://appleid.apple.com", "aud": "<app id>", "exp": 1611852260, "iat": 1611765860, "jti": "<token id string>", "events": "<Event String>" }
General Event Structure
Code Block { "type": "<event type>", "sub": "<apple user id>", "event_time": 1611765847700 }
Event Types
Here are the events I've received so far.email - user's email
is_private_email - is the email an apple email proxy email.
email - user's email
is_private_email - is the email an apple email proxy email.
We are also facing the same issues while trying to integrate.
The documentation leaves out too many questions unanswered and we have to rely on the community and third-party information in order to implement anything to start with and yet, a lot of try-n-error will be coming up most likely. Simply the fact that we have to search for answers outside of Apple's documentation has already made us 3 times the time we originally had planned for this integration.
The following is a review of the current documentation at Processing Changes for Sign in with Apple Accounts, respecting all pages it links to.
Overview
These notifications are JSON Web Tokens (JWTs) ...
This is wrong. The content seems to be a JSON object with only one field named payload which contains the actual JWT.
Set Up the Endpoint URL
All JWTs arrive at the same endpoint URL.
What exactly is meant by "all" here?
The following information from Enabling Server to Server Notifications may have an impact here:
A Server to Server endpoint URL can only be registered on a primary App ID.
Combining those two, my interpretation of the sentence would be:
Notifications for all apps within the same App Group, identified by the primary App ID, arrive at the same endpoint URL.
That would clarify it a lot from the beginning, including resulting limitations.
Also:
Your server examines the JWT and performs work according to the type in the events array in the token.
What do you mean by "examine"? I am pretty sure you're talking about Validating a JWT, but it would be really helpful to use industry standards terminology to avoid uncertainty at the readers side.
Additionally, the events is not an array, so that is misleading information here.
Open Questions:
POST.Content-Type have?Content-Length be correctly set?503 or other 5xx status codes?Would also be nice if there was some reference to the fact that AppleID (at least at the moment) conforms to the OpenID Provider Configuration (see https://openid.net/specs/openid-connect-discovery-1_0.html#ProviderConfig - fun fact: this forum blocks URL's for openid.net, maybe because of previous debates) by providing the following well-known location:
That tells us the location of the JWK Set for getting the public keys as well.
Examples
In section Process a User’s Email Forwarding Change we can see the following example (note the JSON syntax bug - I hope we won't see such things in real life):
{
"iss": "https://appleid.apple.com",
"aud": "com.mytest.app",
"iat": 1508184845,
"jti": "abede...67890",
"events": [
{
"type": "email-enabled",
"sub": "820417.faa325acbc78e1be1668ba852d492d8a.0219",
"email": "ep9ks2tnph@privaterelay.appleid.com",
"is_private_email": "true"
"event_time": 1508184845
}
]
}
Now, according to the example that @MikeNV provided and from other community sources that is simply wrong, since the events claim is a string and not a JSON array.
Open Questions:
iss always be https://appleid.apple.com?aud an App ID? If so:
events is a string, how to parse it correctly?
type have and what do they refer to?The situation is even worse.
On https://developer.apple.com/documentation/sign_in_with_apple/processing_changes_for_sign_in_with_apple_accounts Apple is stating, that "account-delete" is sent as a type in case a user deleted his or her apple id. The event type we actually saw in production was "account-deleted".
While we of course can't be sure if it is actually a typo, or some additional undocumented event type, I assume that this is a typo in the documentation.
Hi there, Could you please share how you managed to receive the account-deleted notification? I actually tried deleting my Apple ID via https://privacy.apple.com/, but I never received the notification on my server. I can't seem to figure out how to trigger it properly. How did you make it happen?
