Welcome to the Email API reference. This section covers the core concepts you need before diving into endpoints.

​
Authentication (at a glance)

All requests require an Authorization header with a Bearer token (your authToken). For endpoints that operate on a connected account, include X-Rollout-Credential-Id as well.

​
Write behavior and propagation

Writes apply only to the system tied to the credential you provide in X-Rollout-Credential-Id. Rollout does not automatically propagate writes to other systems. If you need multi‑system sync, call each credential explicitly or use Sync to DB plus your own orchestration.

​
Response shape

List endpoints typically return a data array plus a _metadata object with pagination details like offset, limit, total, next, and nextLink when available.

Next steps

  • Read Authentication for header details and example requests.
  • See Pagination for how list endpoints are navigated.
  • Review Errors for status codes and error payloads.
