Rapyd has created a simple Postman collection to help get you started. It is a great way to quickly get a TTFHW and see many of our requests and responses in raw JSON format.
Keep in mind that you will still need to go back and sort out your authorization headers and request signature file later. This collection skips that step and there is a pre-built sandbox that comes with the collection as well – so all you have to do is add in your API keys and test the Rapyd API endpoints within seconds of importing into your client.
