Error Handling

RevenueCat uses standard HTTP status codes to indicate the success or failure of an API request. Codes in the 2XX range indicate the request was successful. 4XX codes indicate an error caused by the client. 5XX codes indicate an error in RevenueCat servers.

Successful modifications return the modified entity. Errors return the following fields:
