Last updated: July 10, 2026
Welcome! These API Guides help explain terminology and usage details for our Denim API. This API provides an interface primarily for submitting loads/invoices into Denim, which enables our financial tools to be used with third-parties, such as Transportation Management Systems (TMS), limiting duplicate data entry for mutual clients.
Getting Started
Steps to Launching the Integration:
Contact our partnerships team to acquire a Denim Sandbox account
Review our documentation
Developer Guide
Schedule a Technical Overview or Technical Design Review (optional)
We highly recommend our partners participate in this call. By reviewing your design, we will be able to significantly cut down on the rest of the time to develop the integration
The Denim team will answer any questions you have
We will also identify areas that we know may cause delays / hinder the progress of the integration
Develop the integration using Sandbox Data
Integrators will be given credentials to a unique Denim staging environment with preloaded data to mimic the characteristics of the Denim production environment and create simulated responses for the development of the integration
If you're having difficulties with your sandbox credentials you can reach out to Denim Support for assistance
Schedule a Testing / QA call (required to go live)
Prior to the QA call Denim request partner provide sandbox credentials
Denim can identify bugs within the integration that may arise and provide suggestions to improve the integration
By enabling Denim with credentials you provide us the ability to offer additional support to your team and to the customers leveraging the integration
