Hi everyone,
I'm planning an iOS app that provides a personalized invitation-card creation service, and I'm trying to determine the correct payment method before starting development.
The flow would be:
User selects an invitation template. User enters their event/invitation details. The app generates a watermarked preview. User proceeds to checkout. User pays for the creation of the final personalized PDF. After successful payment, our backend places the request into a processing queue. The PDF is generated asynchronously on our server. Once completed, the user receives a notification and can download the final PDF.
The purchase does not unlock an app feature, subscription, membership, or ongoing access to digital content. The user is paying for a specific personalized invitation document to be generated based on their selected template and information.
Each template can have a different price.
My question is:
Would this type of personalized document-generation service be required to use Apple's In-App Purchase, or could an external payment processor such as Razorpay be used?
I have reviewed the App Store Review Guidelines, particularly the sections concerning In-App Purchase and physical goods/services, but I'm not certain how Apple classifies a personalized digital document-generation service like this.
If anyone has implemented a similar business model or can point me to the relevant Apple guideline or an official Apple clarification, I would really appreciate it.
I'm asking before development so that the payment architecture can be designed correctly from the beginning.
Thanks!
