API Authorization

To access the ALTCHA API, you’ll need an API Key, which you can create free of charge using the API itself.

Using API Keys

After creating an API Key, include it with every API request using one of the following methods:

  • As a URL parameter: ?apiKey=ckey_...
  • As an HTTP header: Authorization: Bearer ckey_...


For assistance with authentication issues or API errors, consult the API errors documentation.
