Changelog

Notable changes to the public API are recorded here. The API is versioned under /v1; see Versioning for our compatibility policy.

Unreleased

Added

• Discovery endpoints. GET /v1/custom-fields, GET /v1/automations, and GET /v1/tags list what your company account accepts, so you can build valid lead payloads instead of guessing. See Discovery.
• File uploads for file custom fields. GET and POST /v1/attachments/custom-field-file-url provide a presign, upload, confirm flow for attaching a file to a lead's file custom field. See Attachments.

Changed

• POST /v1/webhooks/leads: the external id field is now capped at 50 characters and returns 400 when exceeded, rather than failing later during asynchronous processing.
• Rate Limits now documents the 60 requests per 10 minutes limit on the custom-field upload presign endpoint.

Earlier

• Initial public developer documentation: authentication, conversations, leads, messaging channels, inbound lead intake, and outbound webhooks.
