Build with the PostCo Returns API

The PostCo API allows you to programmatically access and manage your return orders. Query return details, track statuses, and integrate returns data into your internal systems, analytics tools, or custom applications. Built on REST principles with JSON responses, the API is designed for straightforward integration and reliable performance.

Getting started

To get started, generate an API key from your PostCo retailer dashboard, then read about how to authenticate your requests and query your return orders. The API uses standard HTTP methods and returns JSON responses, making it compatible with any programming language or tool.
