Introduction

This Postman collection and environment show how to retrieve the Municipal Market Monitor (TM3) bulk file via the Delivery Platform—also known as the Data Platform or RDP using the Client File Store (CFS) API REST API.

You can use this Postman collection to test your RDP CFS TM3 account, package-id, and generate the code.

Please note that this Postman collection is intended for demonstration purposes only and is not optimized for production use.

Important Note:

• The collection has not been tested with Insomnia application.

What If I Use Others Bucket?

This Postman collect workflow also mostly compatible with other CFS API buckets (bulk-ESG, bulk-GreenRevenue,bulk-Symbology,bulk-FMRD, etc.). However if your buck file is in zip, or tar.gz format, you may need to manual download a file on step 4.
