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.

contactIdID!required
afterString

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.

Behaviour

A read. It rejects an Idempotency-Key header with 400 bad_request.
