Tecron Public API Reference Auth Queued Delivery Webhooks Errors Postman

defaultMessage Invalid API key or secret.

invalid_api_key

The key id / secret pair was not accepted.

What to do

  1. Confirm X-Tecron-Key is the full tk_live_… / tk_test_… id from the dashboard.
  2. Use the secret from create/rotate (ts_…). Secrets are shown once — if lost, rotate the key.
  3. Prefer X-Tecron-Key + X-Tecron-Secret (or Bearer keyId:secret). Do not send X-Api-Key.
  4. Check for whitespace, truncated copy/paste, or swapped key/secret.
  5. If the key was revoked or expired, create a new key and update your server config.
