Cleaning up Azure Functions resources
You can use the following steps to delete the function app and its related resources to avoid incurring further costs:
- In your browser, navigate to https://portal.azure.com/.
- In the Azure portal, in your function app’s Overview blade, select Resource Group.
- Confirm that it contains only resources that you want to delete; for example, there should be a Storage account, a Function App, and an App Service plan.
- If you are sure you want to delete all the resources in the group, then click Delete resource group and accept any other confirmations. Alternatively, you can delete each resource individually.
