Accessing the First Class API for custom integrations

Created by Customer Support, Modified on Wed, 11 Mar at 10:58 AM by Customer Support

First Class API overview

The First Class API enables customers and partners to securely connect First Class Software with third-party systems and custom applications. It is used to help First Class users build integrations that automate data sharing, streamline workflows, reduce manual administration, and extend the platform’s functionality to suit their business needs. Common use cases include syncing customer or class data, connecting payment or reporting tools, and supporting custom operational processes across other software platforms.

Access to the First Class API is only available under elite subscription plans.

Customers can be provided with documentation and API credentials on request if they have an eligible plan.
