Inboundr REST API reference: base URL, request and response conventions, ID prefixes, and every resource for receiving email programmatically.
The Inboundr REST API is a small JSON API. Every endpoint is authenticated with a bearer token, returns JSON and uses standard HTTP status codes.

Content-Type: application/json. - Authentication: every request needs an
Authorization: Bearer inb_…header. See Authentication. - Responses: always JSON. List endpoints wrap results in
{ "data": [...] }, and paginated lists also includenextCursor. - Errors: responses outside the 2xx range include an
errorfield. See Errors. - Timestamps: ISO 8601 strings in UTC, such as
2026-07-20T10:30:00.000Z.
