How to connect to QuickBooks

To allow your customers to link your application with their QuickBooks accounts, you need to set up a QuickBooks App and submit your application credentials to maesn.



Before you begin, make sure you have the following:

  • A QuickBooks account with administrator permissions.

You can sign-up for a free trial at, if you do not have a QuickBooks account already. Note that you will not need to use this QuickBooks account for anything else than managing the QuickBooks App and, if you want to, becoming a QuickBooks partner later.


Create the QuickBooks App

In this step we create the App that a user can choose to install into their QuickBooks instance to authorize the integration with your application.

  • Navigate to the QuickBooks developer portal and log in, if you are not already logged in.
  • On the tab “Apps”, click “Create an app”.
  • Select the QuickBooks Online and Payments option.
  • Give your app name: This should be your application’s name. When your users link their QuickBooks account, they will see that “App Name” is requesting to integrate with their QuickBooks account.
  • Select the scope.
  • Click “Create App”.
  • In the next screen, click on “Key & credentials” in the left-hand menu.
  • Click on “Add URI” and add the redirect URI:

Configure your integration in the maesn API

In the last step, we setup your API tenant with your App’s details:

  • Get in touch with your contact person at maesn to submit the client id and client secret.

If you are not sure who your technical contact is, do not hesitate to reach out to us via, but do not enter your client credentials directly in the email. That’s not safe!

Becoming a QuickBooks Partner

Anyone can become a QuickBooks app partner. The requirements and steps to become a partner are detailed here.

Note that before you become a QuickBooks partner you will only have access to their development environment. Once you become a partner you will have access to their production environment.
