I am an administrator on this project, and I connected the RevenueCat extension on Stripe. The Stripe App Integration on RevenueCat was selected by the owner of the project. I am still getting this error:

{ code: 7103, message: "The receipt is not valid." }

whenever I try to post a call to 

curl -X POST \
  https://api.revenuecat.com/v1/receipts \
  -H 'Content-Type: application/json' \
  -H 'X-Platform: stripe' \
  -H 'Authorization: Bearer strp_XXXX' \
  -d '{ "app_user_id": "XXX",
  "fetch_token": "sub_XXX"
  }'

I also tried using server to server notifications, and the same error occured. What could be other possible issues for this to happen? I have not tried deleting the Stripe integration and doing it again yet.

Thank you for your replies,
Calda
