It's now easier than ever to connect your systems to Adfin

API keys are now live in Adfin, so connecting your other systems to Adfin is easier than ever.

Not every invoice starts in Xero or QuickBooks. Some businesses invoice from their own software, or from tools like Zapier or n8n. API keys give those systems a direct way to work with Adfin.

What you can do

  • Send invoices, payment requests and customers to Adfin, and read them back
  • Set up a separate key for each system you connect, with its own permissions and expiry
  • See every request your system makes

How to set it up

An admin on your account goes to Settings, then Developer portal, then API keys, and creates a key. Give it a name, choose what it can do and how long it lasts, then add it to the system you're connecting.

Keep your keys safe

You'll only see each key once, so copy it somewhere safe straight away. Only use a key on your own servers, never in a website or an app.

Who it's for

API keys are for connecting your own systems to your own Adfin account. If your invoices already start in Xero or QuickBooks, Adfin picks them up automatically and you don't need one.

If your software emails invoices out, there's an even simpler option: send them to Adfin with Invoice from email, with no technical setup.

Get started

It's live now. Go to Settings, then Developer portal, then API keys in the console to create your first key. If you'd like to see how it would work with your systems, book a demo.
