Question

Why is there no "app_id" sent with the webhook for PROMOTIONAL products?

Hi,

we are using webhooks for updating user profiles in our database. So far everything worked fine, but from today (or maybe yesterday) we can’t do this anymore for promotional “purchases” because the webhook event body is missing the app_id property. It is there for regular purchases.

promotional:

"api_version": "1.0",
  "event": {
    "aliases": [
      "xxxxxxxxxxxxxxxx",
      "$RCAnonymousID: xxxxxxxx"
    ],
    "app_user_id": "xxxxxxxxxxxxxxxx",

regular:

  "api_version": "1.0",
  "event": {
    "aliases": [
      "$RCAnonymousID:xxxxxxxxxxxxxxxxxxxxxxxx"
    ],
    "app_id": "appd5b6xxxxxxxx",
    "app_user_id": "$xxxxxxxxxxxxxxxxxxxxxxxx",

Is this intentional or a bug?

Thanks!

Hi ​@womo!

This is intentional! The app_id isn’t included in webhooks for promotional purchases because, as a RevenueCat specific feature, the purchase isn’t tied to a specific app within your project but rather the project as a whole.

Hi. Thanks for the explanation. :)

so what is the correct approach for granting entitlements to users with the API? 
Sometimes we distribute the app on the web and need to activate an entitlement for an app. That means a project, not an specific app (android / ios etc). We have three projects on RC and need to identify the purchased app in the webhook.

Hey ​@womo,

Thanks for elaborating on your use case - unfortunately we don’t expose that information in promotional webhooks. 

What information do you have about the user when they download the app from the web?
