API Connection To Third Party Software

New Opportunity

This may be lengthy so please forgive me...

I am interested in connecting an app to a third party software called PlanGrid. PlanGrid is a blueprint management program (upload, markups, RFI's, highlight, versions, etc)
https://www.plangrid.com/


PlanGrid seems to have a decent API for connecting to their software but I am a little out of my league on this one. They have a web based option, a Windows App and a mobile app.

API Documentation....https://developer.plangrid.com/docs/introduction

SDK.....https://github.com/plangrid/plangrid-api-net

Here is what I want to attempt to do:

When we create a project in our app, PG has a Create Project API as well....we seem to be creating all of the information needed to achieve that in PG.

Next step would be to upload a drawing to a project, edit it in PG and have that drawing reside as a file attachment in the project. When I attach the drawing in QB, it would also upload to PG under the project.

I see it, I get it, not sure where to start. I am having a call with one of their software engineers and also to get setup with them and get a user token for their software as well as to provide them with out QB account information so that their software will allow a connection from us.

Just looking for some ideas and direction on what type of pages I need to build to get started

Have some place holders already started....easy part is done!
