issue with sending a message to groups

[jonabert]

The problem

when I copy paste the instruction from the API documentation to send a message to a group
by doing
curl -X POST -H "Content-Type: application/json" -d '{"message": "test 123", "number": "+YYYYYYY", "recipients": ['MYGROUP']}' 'http://127.0.0.1:8091/v2/send'
I get invalid request {"error":"Couldn't process request - invalid request"}
