Create snapshot with Vultr API in bash

redo

I've try to do a weekly backup an Vultr instance according to https://www.vultr.com/api/#snapshot_create

My script is

date=$(date +"%Y_%m_%d")
DESCRIPTION="vps_"$date
API_KEY="my API key here"
echo "{'SUBID':32423432, 'description': '$DESCRIPTION'}" >> vultr.info
curl -i -X POST --data-binary @vultr.info https://api.vultr.com/v1/snapshot/create?api_key=$API_KEY --raw --trace-ascii /dev/stdout --header "Content-Type: text/plain" --connect-timeout 30`

The authentication is OK, but there is an error "Invalid server. Check SUBID value and ensure your API key matches the server's account"

Do you have some hint for me?

Thanks

Your SUBID value is probably wrong or in the wrong format?

It is very unlikely as I took it from https://api.vultr.com/v1/server/list?api_key=xyz

I guess the problem is in this line

echo "{'SUBID':32423432, 'description': '$DESCRIPTION'}" >> vultr.info

But I don't know what is the correct way to pass the info to API

Just for fun, tried sending as regular post?

Edit: I should clarify I of course mean no JSON, just regular form post request.

You are perfectly right. I've just opened a ticket to Vultr and received the same answer. Just POST them as form variables (application/x-www-form-urlencoded) and it works.
