qbo-oauth2.psgi

Purpose: Demonstrates accessing Intuit API via OAuth2 and perl.

License: Use at your own risk. If you like it maybe buy me a beer sometime.

Notes:

This code tries to minimize the use of libraries.
This code tries to maximize readability to better convey concepts.
This code looks nothing like my production code.
This code does not show the disconnect endpoint, which you should implement.
Plack is used because I am most familiar with it.
If you try to contact me I may not help you or even reply.

General Gotchas:

Ensure the authentication values do not contain newlines.
If you POST then you need to submit the parameters in the body.
When accessing the API the URL changes for production VS sandbox.
You can only use localhost for the redirect URL in the sandbox.

To install and run:

apt-get install libplack-perl libplack-middleware-session-perl
Add redirect URI on QBO app keys tab.
Update $Params from QBO app keys tab.
plackup -r qbo-oauth2.psgi
