Replaces the settings of one destination that was added to an export, such as its fields, file format or connection. Send the whole destination in the same shape as destination on create; each added destination in a read carries its current settings in that shape as destination, so read it, change what you need, and send it back. The type cannot change, and the connection must not be one another destination on the export already uses. The export's original destination is changed with PUT /api/v1/exports/{id} instead.
