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.
1

Prerequisites

Before you begin, make sure you have the following:
  • A QuickBooks account with administrator permissions.
You can sign-up for a free trial at https://quickbooks.intuit.com/eu/#pricing, 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.
2

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 com.intuit.quickbooks.accounting 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: https://api.maesn.dev/auth/callback/quickbooks
3

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.

​
Sandbox environment

QuickBooks has different URLs and credentials for their production and sandbox environments. To generate a sandbox end user account you have to use the quickbooks-sandbox target system. Inside quickbooks, you can create sandbox credentials with the same steps as the production credentials, you just need to create sandbox credentials instead of production credentials. You also have to use the following callback URL for the sandbox environment: https://api.maesn.dev/auth/callback/quickbooks-sandbox

​
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.

​
Webhooks

Quickbooks supports the following resources:
  • ACCOUNT
  • BILL
  • CUSTOMER
  • INVOICE
  • ITEM
  • JOURNAL_ENTRY
  • PAYMENT
  • SUPPLIER
  • EXPENSE
Quickbooks sends CREATED, UPDATED, DELETED, MERGED, VOIDED and EMAILED events. Before you start using webhooks for QuickBooks, you will need to contact us to receive the callback URL to use in your QuickBooks App configuration. Inside your QuickBooks app, you will choose the resource and eventType you want the webhooks enabled for. Once configured, this setup will be valid for all users of the app. Now, for each authenticated end user, call Maesn’s create webhook endpoint POST /webhooks with the following body:
Example code snippet
    const response = await axios.post(url, {
        "callbackUrl": callbackUrl
    }, {
        headers: {
            'X-API-KEY': apiKey,
            'X-ACCOUNT-KEY': accountKey
        }
    });
It will return the id associated with the subscription:
Example response
{
    "data": {
        "id": "550e8400-e29b-41d4-a716-446655440000",
        ...
    },
    "meta": {}
}
At this point, your system is ready to receive end-user–related events at the callback URL you provided. Quickbooks retrieves a list of events. The event response will provide the following information:
Example event body
{
    "eventType": "CREATED",
    "filterDate": null, //not supported by quickbooks
    "resource": "INVOICE",
    "recourceId": "1",
    "userId": "23631355"
}
To delete the webhook subscription, you can call the DELETE /webhooks/{webhookId} endpoint.
