Explain the authentication steps for a custom in‑house CRM integration

Create a Connection in Certain Signal, choose the authentication method your CRM supports (OAuth 2.0, API‑key header, or Basic Auth), then enter the required credentials—Endpoint URL, Client ID and Client Secret for OAuth 2.0, or Username and Password for Basic Auth—exactly as the CRM admin provides. After saving the Connection, map your event tags to the CRM fields in a Flow and activate it so data is sent securely using the configured authentication.

Signal Integration with Advanced Webhooks Guide – details on Connection setup and OAuth 2.0 / Basic credentials. Signal Integration with Webhooks Guide – outlines webhook‑based authentication options. Follow‑up: Do you already have an OAuth 2.0 client set up in your CRM, or would you prefer using an API‑key or Basic Auth approach?
