Twelfth Webhooks
Twelfth uses signed inbound webhooks as part of managed integrations such as Shopify and service messaging. Those callback URLs are configured between Twelfth and the provider, verified with the provider’s signature scheme and are not customer-facing endpoints for arbitrary event delivery.
Twelfth does not currently provide a customer-configurable outbound webhook API. Do not build an integration against an observed provider callback path: its payload, authentication and lifecycle belong to that managed connector and can change with the provider contract.
Request an integration
If you need Twelfth to read from an internal API, data warehouse, object store or scheduled export, describe the source, authentication model, required data and update cadence. Twelfth scopes custom integrations as read-only pipelines and documents the agreed interface with the customer.
