In approximately one week, on April 9, 2025, we will make a small change to the RevenueCat-calculated IDs for any new non-subscription purchases happening after that date. We will increase the length of the IDs to 25 characters to avoid collisions between different purchases. This ID is exposed via our SDK, Web API, and webhooks. Subscriptions and purchases that happened before the change will not be affected.
This will likely not have any impact on the vast majority of developers – the ID was a string and remains a string, only longer (25 characters) and with more potential characters (A-Z, a-z, 0-9, -, =, and _). If you are ingesting this string in a database on your side, please make sure that the database schema accepts strings of that length.
If you have any questions about this change, please feel free to ask them below.
