We are working on improvements of our speed and fault-tolerance. In order to achieve that we need to make few changes in API. You can safely ignore this message if you use our new link identifiers only (they look like lnk_abc_abc123).
Starting from now you need to provide domain_id parameter in query string if you try to update or delete link by identifier.
DELETE /links/1234567890 => DELETE /links/1234567890?domain_id=12345 POST /links/1234567890 => POST /links/1234567890?domain_id=12345 DELETE /links/lnk_abc_abc123 => DELETE /links/lnk_abc_abc123 // no need to add domain id
