Response fields

Field	Type	Description
errCode	int	Business error code. `0` means success.
errMsg	string	Short error message.
errDlt	string	Detailed error information for troubleshooting.
data	object	Endpoint-specific response data.
data.friendsInfo	array	Matching records. Each item follows `FriendInfo`.

Error response

When a request fails, OpenIM returns the same error envelope. See Error codes for the full handling model.

{
  "errCode": 1004,
  "errMsg": "RecordNotFoundError",
  "errDlt": ": [1004]RecordNotFoundError"
}

Scenario	Possible cause	Recommended action
Authentication failed	`token` is missing, expired, or not an administrator token.	Issue a new administrator token and keep it on the backend.
Traceability is weak	`operationID` is missing or reused across many requests.	Generate a unique `operationID` for every request and log it with the response.
Validation failed	The request body has an invalid type, missing field, or unsupported enum value.	Compare the payload with the request table and retry after correcting the fields.

Permissions and limits

Call this endpoint from a trusted backend service.
Log operationID, the endpoint path, and the response error fields for troubleshooting.
Treat write operations as state-changing. If a retry follows an uncertain failure, check the resource state first.
