# API workflow

Learn about Avalara's API workflow and how to access the Postman collection for integration support.

To help you with your integration, Avalara provides a workflow that consists of a collection of APIs. This collection includes a set of JSON files that can be opened in [Postman](https://www.postman.com/). If you're a certification partner and you find yourself getting stuck, simply contact Partner Launch at [DG-PartnerLaunch@avalara.com](mailto:DG-PartnerLaunch@avalara.com) and tell them which part of the workflow you were on when you ran into an issue.

The Postman collection is available here: [AvaTax Cross Border Story](https://documenter.getpostman.com/view/447092/UVCBC5bu).
