API and Developers

Hi, We are a developer and building a custom web platform for one of our client who is using smartsheet. Our platform needs to get data from smartsheet and need to show the data in our custom UI. Could anyone recommend the APIs we should be using for this?

June 29, 2026 Great news for developers building integrations with webhooks: sheet webhooks now support custom HTTP headers.

The third-party system requires strict IP-based allow listing for any external connections and cannot accept DNS records or hostnames as a substitute. The challenge: Smartsheet's documentation only references webhooks.smartsheet.com for inbound…

I have an automation that makes a copy of a folder and moves it into another folder using Make.com. Within the new folder is a sheet with a form, and I simply want to generate a QR code for this form using the form's URL returned by the Smartsheet API.
