Where to go with questions about the Klantly API.

Look it up first

  • Check the error codes: every error has its own page with cause and solution.
  • Use the search bar at the top of this documentation.
  • The Usage tab under Integrations → API in Klantly shows your recent requests with their status.

Contact

Still stuck? Contact Klantly support through the support button in Klantly. Please include:

  • the request_id from the error response or the X-Request-Id header;
  • the endpoint and the time of the request;
  • what you expected and what happened.

Warning

Never send your full API key. The prefix, for example kly_4fZ2mQ8v, is enough to recognise the key.
