There's really no better tool to build, run, test, document, and share HTTP requests than Postman. We use it internally for all sorts of stuff, and with the recent addition of the 'Run in Postman' button feature... it was a no brainer for us to whip up a public collection to share with the developer community.
So here it is! A public collection with 45+ Vinli requests... preloaded with oodles of sample data via Virtual Vinli.
This collection is fully furnished, no config required...just add the collection to the platform and start running requests. Once you learn your way around though, you might want to update some of the requests with your own App Id/Secret.
