Before you can start using the CryptoProcessing API, generate and activate an API key. Use a Master key for full API access, and optionally configure Custom keys that can call only selected endpoints. You can restrict each key to trusted IP addresses. To receive webhook notifications, you also need to register a callback URL and keep a Master key active. CryptoProcessing signs callbacks using the secret key of the active Master key. For details on authenticating your requests, refer to the API reference.
