/custom_fields/{custom_field_gid}Update a custom field
Updates an existing custom field while preserving any properties you omit from the request. Supply only the properties you want to change, because the custom field's type and an enum custom field's enum_options cannot be updated here. The authenticated user must have the custom_fields:write scope, and locked custom fields can only be updated by the user who locked them.
- RetriesRetries up to 2×, 500ms backoff, 30s timeout.
The custom field properties to update; only properties included in the data object are changed.
A 400 is returned when a parameter or request value is missing or malformed. A 401 is returned without a valid authentication token, a 403 when the authenticated user lacks access or the required custom_fields:write scope, a 404 when the custom field does not exist, and a 500 for a server-side failure. Do not attempt to update type or enum_options with this endpoint.
