Remote Config Changes for Store SKU

The storeSku will be the combination of prodcut_prefix value from Remote Config and min_price from course modes in enrolments API.

Implementation

1. Fetch the courseSku and storeSku using the enrollments API.

2. Utilize the courseSku for the add_to_basket and checkout APIs.

3. Handling Play Console purchases:

   • Store courseSku within the purchase as a payload using obfuscatedProfileId (ref).
   • Utilize the storeSku for the purchase.

4. After a successful purchase:

   • Retrieve the courseSku from obfuscatedProfileId.
   • Extract storeSku from the product ID.
   • Implement a similar approach for the restore process.

5. Share this information with the execute API:

   • Upon a successful response, consume the purchase.
   • Refresh the courses.

6. In case of a restore (payment done, but execute API or consume not called):

   • For Execute:
     • Leverage the existing mechanism for execute.
     • Integrate consumption following the above approach.
   • **For Consume (when execute is called but the product isn't consumed):
     • Proceed with the consumption straightforwardly.
     • The course is already verified from the server and locally.**

7. Tada!!
