# Superwall Forward Superwall webhook events to AppSprint so paywalls, trials, and subscription changes are attributed to the original install. ## Webhook endpoint ``` https://api.appsprint.app/v1/webhooks/superwall ``` Paste this URL into Superwall → Settings → Integrations → Webhooks. ## Authentication Superwall signs webhooks using Svix. AppSprint verifies the signature using the webhook signing secret stored in your app's dashboard under Integrations → Superwall. ## Event mapping | Superwall event | AppSprint event | |----------------|-----------------| | transaction_complete | purchase | | subscription_start | subscribe | | free_trial_start | start_trial | | subscription_renew | renewal | | subscription_cancel | cancellation | | subscription_expire | expiration | ## Required: appsprintId user attribute For webhooks to be matched to an attribution, you must set the `appsprintId` user attribute in Superwall from the SDK. ## SDK snippets Set the user attribute after the AppSprint SDK is configured. In React Native and Flutter, `getAppSprintId()` is asynchronous, so await it before calling Superwall. See the Superwall docs page for platform-specific code snippets. --- ## Docs navigation Use the Markdown URLs when reading the docs programmatically.
