The Tesel Data API

The Tesel Data API is organised around REST. Our API accepts form-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.

We also make available a sandbox environment upon request where you can use your the Data API in a way that doesn't affect any live data or interact. The API endpoint and API key you use to authenticate the request determines whether the request is live mode or test mode.

The Tesel Data API doesn't support bulk updates. You can work on only one object per request.

The Tesel Data API will differ in future iterations as we release new versions to tailor functionality as we grow along our roadmap. All versions and their differences will be documented within this portal.
