ACH with QuickBooks Desktop - which API?

0
votes

We've been using the QBMS for our QB DESKTOP clients using this QBMS API: https://developer.intuit.com/docs/0100_quickbooks_online/0200_dev_guides/payments/z_qbms_payments/0060_documentation/transaction_types This continues to work fine for credit cards, but now we need to support ACH payments for QB Desktop. What API(s) can we use for this? Note that these QB Desktop clients use a "connection ticket" for authentication.

We also have support for QB ONLINE via the new QBO APIs as well as the new QB Payment APIs that does support ACH. This payments API uses OAuth authentication (Access Token Secret) and not the "connection ticket", so is there a way to use this API in conjunction with QB DESKTOP? If so, where does the client (the one that has the Intuit merchant account) go to obtain the Access Token Secret? Note that the client does not have the QB Online app, they just have a merchant account with Intuit and QBD. So the usual way of going to the Intuit app store and clicking the [Get App Now] button will not work.

ACH payments for QB Desktop. What API(s) can we use for this?

Use the QuickBooks Payments API. It's your only choice -- it's the only API Intuit offers which supports ACH. It will do credit cards as well as ACH.

Note that these QB Desktop clients use a "connection ticket" for authentication.

They won't use a connection ticket anymore, they'll use OAuth.

so is there a way to use this API in conjunction with QB DESKTOP?

Yes.

If so, where does the client (the one that has the Intuit merchant account) go to obtain the Access Token Secret?

You provide them with a webpage they visit to get the tokens/secrets.

They go through the same OAuth connection process that QuickBooks Online users go through except you pass a flag indicating the you only want to connect to Payments, and not to QuickBooks Online.

Specifically, look at the datasources.payments option referred to here:

Note that the client does not have the QB Online app, they just have a merchant account with Intuit and QBD.

That's just fine. They will NOT need a QuickBooks Online account.

So the usual way of going to the Intuit app store and clicking the [Get App Now] button will not work.

That's fine, they will NOT be going to the App Store to get connected.

Instead, you'll provide a webpage for them to visit, which kicks off the OAuth flow, and lets them get their OAuth creds.
