BC-1109-1: a record deletion is not sent to Bitrix24 again
Old format supported until: not provided
Before
A DELETE of an entity record — for example DELETE /v1/deals/{id}, DELETE /v1/contacts/{id}, DELETE /v1/leads/{id} or DELETE /v1/companies/{id} — was repeated on the Vibecode side when the account was temporarily unavailable (a 503 with no error code) or answered with a redirect, and one deletion reached the account more than once. A repeat after a deletion that had already happened was refused by the account because the id no longer existed, so the client got a refusal for a deletion that had gone through.
After
The deletion is sent to Bitrix24 again only after a refusal the account gives before running the method — the request rate limit QUERY_LIMIT_EXCEEDED. Temporary unavailability and a redirect both answer 502 BITRIX_UNAVAILABLE, with no repeat. A successful deletion still answers HTTP 204.
What integrators should do
After a 429 on DELETE, wait the number of seconds given in Retry-After and repeat the request: the deletion was not applied. After a 502 or 503, read the record first: the deletion may have been applied, and a repeated DELETE for it answers with a "not found" refusal.
BC-1109-2: Application grants for connector reads
Old format supported until: not provided
Before
Connector calls from applications were allowed by the key scope and the owner's audience. Writes required approval.
After
Applications read data through /v1/connectors/mcp only with a current administrator grant for the company connection. The key owner audience does not replace a grant. Application writes are no longer supported and do not create approval tickets. GET /v1/connectors returns appState for every connector; GET /v1/me reports readOnly and refusal codes.
Refusals have HTTP representation 403: CONNECTOR_APP_NOT_GRANTED, CONNECTOR_APP_GRANT_PENDING, CONNECTOR_APP_EXPOSURE_WIDENED, CONNECTOR_APP_WRITE_NOT_ALLOWED, CONNECTOR_APP_NOT_CONNECTED. MCP returns the code in _meta["vibe/error"].code. Widening link access or enabling the external application API suspends the grant until new approval. Cowork access is preserved.
What integrators should do
Submit a connector request for the application: an administrator grants read access to the company connection. Remove write tool calls from the application.
NEW-1109-3: Application connectors and access requests
An application manager can list company connectors using GET /v1/applications/:id/connectors: access status, read-only tools and the application's current exposure. POST /v1/applications/:id/connectors/:slug/access-request submits a request to a Bitrix24 account administrator. Repeating a request while a decision is pending or access is active preserves its status.
NEW-1109-4: Chat file list
GET /v1/chats/{chatId}/files returns one page of chat files — the Media, Files and Voice tabs of the chat side panel. The required group takes one or more of MEDIA, FILE, AUDIO, separated by commas. Optional: limit (1–200), the cursor lastId and, together with it, lastDate, order=date only with group=AUDIO, search — the start of a file name. data holds list, files, users and tariffRestrictions. Requires the im scope; a read-only key may call the route too. A file link that carries credentials is replaced with null in the answer.
