For faster development, we recommend following tools.
Postman is a developer tool which make it easy to invoke REST API resources and receive their responses. We created a set of Postman collection that you can download and import into the program. Don't forget to set postmen environment properties.
Ngrok allows you to expose your local server to the Internet. This tool is super useful if you want to receive webhook calls during development.
RequestBin is another tool useful for receiving webhook calls. With this tool, you can create an online request bin to which you can point your webhook calls. All HTTP details including request headers and body can be examined online afterwards.
