I need to develop a simple PHP application for a client that connects to quickbooks online to populate customer data and invoices.
Is there an easy way to accomplish this or does it really require going through the IPP app setup, including the OAuth setup, etc? This app will only ever be used for this one customer, and I have no intentions to use it elsewhere.
All I really need is a way to hit their API. Any guidance or information on navigating this would be appreciated!
To start development using QB API, you need to create an IA apps in Intuit's appcenter. https://developer.intuit.com/docs/0025_quickbooksapi/0010_getting_started/0010_signup
From the above link you will get - apptoken, consumer key and consumer Secret. You can use the above 3 keys in IPPOAuthPlayground(PFB link) to get the access token and access secret corresponding to your QB Online account. https://appcenter.intuit.com/Playground/OAuth
Intuit provides PHP devkit which you can download from the link below. You can simply plugin the above OAuth tokens in devkit and call any QB endpoints.
