Creating a key

  • Keys start with klo_ and are shown once, at creation. Copy it then because it can't be shown again.
  • Only a fingerprint of the key is stored, never the key itself.
  • Revoke a key any time; revoked keys stop working immediately.

Using it

Send contacts to the ingest endpoint with the key as a bearer token. Incoming rows use the same validation and duplicate checks as a CSV import, and remain scoped to your Workspace. The key decides where data goes, never the request.

Treat a key like a password. If it may have leaked, revoke it and create a new one.
