Every vendor-specific onboarding guide tells you where the webhook settings live, what URL to paste, where to find the signing secret, and how to test. If your vendor isn't listed, use the Custom source shape on the picker and follow the custom-signature guide.
Optional for this source. Create the source, then use the Relin URL when you subscribe.
