Authentication

Monnet APIs support two authentication mechanisms, each aligned with a specific set of endpoints to ensure secure and controlled access:

1. Keyed-Hash Message Authentication Codes (HMAC) This mechanism is used for high-integrity operations that require request-level validation. Applicable endpoints:

   • Create Payout

   • Get Payout Status

   • Get Balance

   • Create Card Pushpayment

2. OAuth 2.0 Bearer Token Authorization This standard authorization protocol is used for endpoints that rely on token-based access control. Applicable endpoints:

• Scanning Account Info

• Get Account Info

Each endpoint must be called using its corresponding authentication mechanism; otherwise, the request will be rejected.
