OAuth2 solution in C# or Java for TDA and Coinbase - Retrieve token from url, decode token and post to 2nd url, store result to database

Would like C# method to call a url, retrieve the string in the returned URL, then decode a portion of that string and pass the decoded string to another url and store the result in a database.


1) Initial URL is

[login to view URL]

2) Response will be like [login to view URL]

3) Copy all text after code=

4) Decode string

5) Pass decoded string to [login to view URL]

grant_type: authorization_code

access_type: offline

code: string that was decoded in step 4

client_id: OEWYL2IRS2L7GYZIPHK2P7F3MCQXBNUS%[login to view URL]

redirect_uri: [login to view URL]

6) Retrieve and store refresh token given in response

2nd Milestone would be to do the same with Coinbase API. TD ameritrade and coinbase have similar OAuth2 flow

[login to view URL]
