Postman Collections For Each Xignite Global Currencies API

Postman Collections For Each Xignite Global Currencies APIFor each of the APIs we add to the Streamdata.io API Gallery we prefer being able to run each API using the Postman development tool, making sure the API definition is 100% correct, and will actually return a response. Once we’ve profiled an API, or set of APIs, we export what is called a Postman Collection, which provides a machine readable definition that can be imported and executed within Postman in a single click. We recently were profiling and benchmarking the Global Currencies API provided by our partner Xignite. Xignite is a global leader in on-demand market data and wanted to publish the 21 separate API paths, and share with our customers, making the market data APIs easier to execute. Here are the name and descriptions of each API provided by Xignite, along with the Run in Postman button, which will load the API into the client for you.

Xignite uses Streamdata.io to deliver its streaming market data solutions, but we want to share the usable definitions for their APIs as we profile them, to help our customers leverage their APIs more effectively. You can proxy and stream some of the real time rates listed above, but we just mostly want to make sure these valuable APIs are within reach–we aren’t always profiling APIs that only can be streamed, as we understand our customers needs are bigger than just what our services deliver.

We will work our way through all of the Xignite APIs, profiling and generating Postman Collections. We will publish a separate story for each one, to try and keep similar APIs grouped together. We also prefer making a separate Postman Collection for each path, which makes it easier to pick and choose exactly which API resource you want to execute–not just load them all into Postman. Providing access individual units of API value that you can use in your applications.
