Amplitude

To integrate Amplitude go to Integrations > Amplitude and set credentials.

You need to enter API Key into Adapty. To find a token go to your Project settings in Amplitude. In case you need help refer to official docs.

Amplitude API key. Copy in and paste into Adapty

Along with events, Adapty also sends the subscription status and subscription product id to the Amplitude user properties.

SDK configuration

Use Adapty.updateProfile() method to set amplitudeDeviceId or amplitudeUserId. If not set, Adapty uses your user ID (customerUserId) or if it's null Adapty ID. Make sure that the user id you use to send data to Amplitude from your app is the same one you send to Adapty.
