The Gigapay API is organized around REST. Our API has predictable resource-oriented URLs, accepts JSON-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs. Our API is available at https://api.gigapay.se/v2/. There is a demo version of the API available at https://api.demo.gigapay.se/v2/. This also serves as a test environment for developers working to integrate with our API. No money flows through the demo environment.
Both the live and demo environment render a human-friendly HTML output for each resource, when the HTML format is requested by a web browser. This allows for easy browsing and interaction with the available resources. We strongly recommend you test our Browsable API before starting to integrate with our API, as it will give you a far more intuitive understanding of the API compared to reading this documentation.
There is also a Postman collection if you prefer. Follow the instructions here to get your Postman environment and collection configured.
