What is the API Integration?

Whether you're building a custom dashboard, automating workflows, or integrating with your own tools—the API gives you full programmatic access to your synced transactions.

FAQs

Can I query transactions by date range via the API?

Not yet — date range filtering is currently an open feature request. Each API request returns all available transactions from the connection (up to 90 days for GoCardless connections).

Want this feature? Upvote the request ""Support from & to filters in the transactions API"" on our feedback board at lunchflow.app/feedback and you'll be notified as soon as it's available.

Can I use Lunch flow as an open banking provider in my own app?

Yes, this is now possible using our platform API. Check out the Developer menu to create new apps.

Can I control which accounts the API key can access ?

Yes! Each API destination has an Account Access tab in its settings, where you can toggle which of your connected accounts are accessible through that destination. If an account isn't showing up in your API results, this is the first place to check, it may simply be toggled off for that destination.

My accounts aren't showing up in the API, why?

If some of your accounts are missing from the API response, check the Account Access settings on your API destination. Each account has a toggle that controls whether it's exposed through that destination. If it's off, the account won't appear in your results. You can find this under your destination settings → Account Access tab.
