Connect your stack
Choose an app to explore ready-made templates or build your own Workflow.
Webhook · Clerk
Receive a JSON webhook containing organization_id and look up the matching organization in Clerk. Connect the Secret Key for the instance that owns the record. Replace the fictional example with an existing ID.
Webhook · Clerk
Receive a JSON webhook containing user_id and look up the matching user in Clerk. Connect the Secret Key for the instance that owns the record. Replace the fictional example with an existing ID.
Choose Clerk in a workflow step and enter the Secret Key from the API Keys page of the instance that owns your records.
Connect your accounts and map the required fields from earlier steps. Test with data you control before activation.
Development and production instances have separate keys and resource IDs. Configure the existing Clerk webhook source with its Svix signing secret to receive events. Some operations require a paid plan, enabled features or production-specific settings. Deprecated operations may be unavailable. File uploads use one File up to 10 MiB; Clerk validates image formats and resource-specific restrictions. JSON responses are limited to 2 MiB: request a smaller page when needed. The Secret Key authorizes Backend API actions; it is not the Publishable Key or webhook signing secret. Reconnect after replacing a key. Revoke the original key in Clerk to end its provider-side authority. Interactive sign-in pages are outside the backend integration. Webhook endpoints are configured in the Clerk Dashboard with a separate per-endpoint Svix signing secret.
