Clear all rows of a table

[Matteo_Menghett]

Hello,

I would like periodically clear my app database (erase all rows). I thought it could be possible with a webhook using as HTTP verb Delete but I am struggling making it done. The JSON body I use is:
{
“Action”: “Delete”,
“Properties”: {
“Locale”: “en-US”,
“Location”: “47.623098, -122.330184”,
“Timezone”: “Pacific Standard Time”,
},
“Rows”: [
<<Start: SELECT(TableToDelete[Key],true)>>
{
"Key":"<<[Key]>>",
}
<>
]
}

Does anybody knows where I am wrong?

Thank you.
