virtual machine deprovision REST API error

Question

dear all,

in order to delete a virtual machine, I call the follow API:

Method: DELETE
URL:
https://management.azure.com/subscriptions/xxxxxxxxxxxxxx/resourceGroups/{resourceGroupName}/providers/Microsoft.Compute/virtualMachines/vmName1?api-version=2022-03-01

I received the follow error:

409: { "error": { "code": "OperationNotAllowed", "message": "Disk XXXXX_aa8411492c1345bf95539ff88f408851 is attached to VM /subscriptions/XXXXXX/resourceGroups/XXXXX/providers/Microsoft.Compute/virtualMachines/YYYYYY"}}

this error regards to the boot disk which is attached anymore.

So I have tried to launch the same API and method with the forceDeletion parameter but the error occours

Does anyone know why?
furthermore, does anyone know the right method and api to deprovision a virtual machine?

thanks very much

I understand you are wanting to delete a VM via REST API but are running into the above error. Can you try running detach disk and then running the delete?

You need to run VM update first to detach the disk. You can find a sample here which is using the data disk.

Please try this and let me know if it works for you.
