Hey, you should check our forums at

For your issue, when you do "POST /v1/projects/1a5/apikeys" in the response it give you back an id. For example
{
"id": "1c2",
"publicValue": "...."
}
Just take that ID and first "deactivate" the key. This will make the key not valid. So "POST /v1/projects/1a5/apkeys/1c2?action=deactivate". Then once the apikey is inactive you can delete DELETE /v1/projects/1a5/apkeys/1c2"
