This is a mini proxy server that lets you receive slack events(over the events API), and forward those events to Postmans webhook.
Slack Events API forwards all subscribed events as an HTTP requests to verified endpoint that you provide. When working with this API in Postman, you can use the Postman's API to create a webhook that can receive these events.
The first step is to verify this URL which cannot be done since you have to respond to the verification request with a challenge code provided by slack. Webhooks in Postman are meant to help you trigger a collection run, and hence, does not provide an interface that let's you describe the response to a webhook request
This repo is a work-around for this limitation, it acts as a proxy between slack's API(the client) and Postman webhook(the server), enabling you to easily complete the verification process while still routing all the necessary events to your Webhook in Postman.
