Complete a task by taskId ALONE, for tasks with NO contact (listMyTasks contact: null; typically deal tasks). Returns the task. isCompleted: false reopens. It REFUSES a task with a contact (it would skip the timeline entry): use completeTask. A contact-less APPOINTMENT completes too (type says so); no task count includes it. It only completes tasks YOU are on: a non-admin key gets a permission error for someone else's. Confirm with the user first.

Variables

The example sends only what the schema requires. Some operations also need one of several optional variables (one filter or another, say); the description above says which.

taskIdID!required
isCompletedBoolean!

Default true.

Response

What comes back under data: a list shows as one entry, and a value as its type.

Errors

400unknown_variable

A variable the operation does not declare. A typo is refused rather than silently dropped.

401unauthorized

No bearer header, or the key is invalid or revoked.

403insufficient_scope

The key lacks the scope the operation requires.

403forbidden

A referenced record does not exist, was deleted, or is outside your organization. The gateway cannot tell those apart.

409idempotency_conflict

A request with this Idempotency-Key is still in flight.

Idempotency

Send an Idempotency-Key of 1 to 255 characters. A finished request retried with the same key replays its stored response, marked Idempotency-Replayed: true; one still in flight returns 409 idempotency_conflict. Keys expire after 24 hours. Write without fear →
