Our API lets you seamlessly integrate your Proper account into your own workflow. Build custom integrations with your software to meet your needs. Even without knowing code. The Proper API is organised around REST. Our API has predictable resource-oriented URLs, accepts JSON request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.
