Sign-in yields "API key is not valid"

[qeggs]

I am attempting to "sign-in" with the postman collection and getting the response "API key is not valid". What might be going wrong here?

I have set the environment variables:

Variable	Initial Value
installid	00000000-0000-0000-0000-000000000000
KeaseApiKey	14445b6a2dba
ApiKey	aaaaaaaaaa.bbbbbbbbbbb.cccccccccccc

I have set my credentials on the body tab:

{
  "identifier":"phone:+15551234567",
  "installId":"00000000-0000-0000-0000-000000000000",
  "password":"MyPassword"
}
