API Documentation
The PaySentinel API allows you to integrate payment monitoring and alerts directly into your WordPress site or custom applications.
Security Overview
All API requests (except license validation) must be signed using HMAC-SHA256.
To authenticate your requests, you must include the following headers:
X-PaySentinel-License-Key: Your active license key.X-PaySentinel-Timestamp: Current Unix timestamp (UTC).X-PaySentinel-Signature: The generated HMAC-SHA256 signature.
API Specification
We provide a standard OpenAPI 3.0 specification file that you can import into tools like Postman, Insomnia, or use to generate client libraries.
Getting Started
Use the sidebar to explore specific endpoints. Most endpoints require HMAC authentication, which you can set up after performing an initial license activation.
