About this integration
Invoice creation, billing, and payment management for small businesses.
There are 3 triggers, 7 search modules and 11 actions available. The integration connects via basic authentication.
How to connect
The credential form asks for API Key and API Secret.
Prefer the interactive builder form? Open it on the app page.
Paste your credentials once — WEXTL® stores them encrypted and reuses the connection across every workflow that needs it.
Enter your credentials below. WEXTL stores them encrypted and uses them only to call the API on your behalf.

Use it in workflow automation
Start with Watch Clients, then add Add a Payment.
The canvas below runs Watch Clients into Add a Payment — watch the video, then drop a node onto the canvas.
Select the Watch Documents trigger and the workflow fires automatically when the event occurs — no polling required.
Then add Delete a Document as the next node. Branch, filter, or hand off to other integrations from there.
The integration includes 14 ready-made modules for finance work — each run logs its inputs and outputs for debugging.
