# API workflow

Learn about Avalara's API workflow and available resources for refactoring.

To help you with your refactor, Avalara provides a workflow that consists of a collection of APIs. This collection includes a set of JSON files that you can open 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: [RESTv1 to RESTv2 Postman collection](https://documenter.getpostman.com/view/7945304/UVJWpKVJ).
