Making API calls from ERP system

[Andre_van_Aarde]

Is it possible through the webhook / actions feature in Appsheets to make API calls to my account software / ERP system through their REST API?

The information I would like to pass is related to fetching and updating various customer fields and product information.

Yes, you can use an action in AppSheet to trigger a workflow that sends a webhook to your ERP.

You can send data from AppSheet to your ERP with POST/PUT/PATCH requests, but you can not GET data from your ERP. For that, try Zapier, Apps Scripts, or see if your ERP can send webhooks to AppSheet’s API.
