Getting an Access Token Using the Resource Owner Flow

You must sign your requests with an access token when making requests to the HotDocs Advance API. This topic describes how to retrieve an access token using the ResourceOwner flow.

Prerequisites

Create a new API client – you must have an existing API client that uses the ResourceOwner flow
Adding a service principal to a client – the API client above must have an associated service principal user

Overview

This request retrieves an access token from Advance, using a service principal account. Once you successfully retrieve the access token, you can then use it to sign requests to the Advance API.
