Bitrix24: REST API docs

Official Bitrix24 REST API documentation for building integrations

VerifiedOnlineNo sign-inRU / CISFreeRead-only

What it can do

  • Find a REST API method and its parameters
  • Example calls for CRM, tasks, drive
  • Answer a documentation question

What data it sees

Public documentation only. Reads none of your portal data.

Do you need an account

No: the server works without sign-in

Official Bitrix24 server, no auth. Gives the assistant the current REST API documentation so it writes correct integration code. It is not access to your portal: CRM and tasks are not readable through it. A separate portal-management server was announced by Bitrix24 without a public address yet (TODO).
