Use it in a flow

Open a flow, open the node library and search for QuickBooks.
Drag it onto the canvas and choose an Operation and your connection.
Map the operation's fields from earlier steps, or click Map with Matt.
Use Test this step to see what it returns, then save.

To start a flow from QuickBooks without a ready-made trigger: a Poll for changes trigger can check one of its list operations on a schedule and pass on only what is new; if QuickBooks can send webhooks, a Webhook trigger receives them at its own URL.
