Postman Collection

Overview

Postman is an application designed to help with API integration and exploration. Intuitive for different tech skill levels, it’s the tool of choice for both experienced developers and those new to APIs to get familiar with available endpoints, requests, and responses. Using our Rampnow Postman Collection, you can start testing our API before you write a single line of code. Explore endpoints, understand request/response structures, and validate your integration setup in an interactive environment.

The Postman collection includes pre-configured requests for all major Rampnow API endpoints with built-in authentication headers and sample payloads.
