Welcome to the Aventus Platform API. # Authentication The Aventus Platform API implements OAuth 2.0, this allows users to grant 3rd party applications full or partial access to their account data without sharing their login credentials. The process involves several steps: 1. Acquire an access token 2. Send the access token in the Authorization header with each request. eg: `Authorization: Bearer ACCESS_TOKEN` Find out more about implementing authentication at https://docs.aventusplatform.com/docs/authentication. # Data Types All API request and response bodies are formatted as JSON.
