I set up a registration / sign in flow in my game using RegisterPlayFabUser and LoginWithEmailAddress, it works perfect. Now I am trying to add other features and wanted to test my new flow with pure API calls, without SDK. I went to a documentation page LoginWithEmailAddress to send "login request" from "Sample request" section and submitted my recently registered credentials. For some reason this didn't work and I received 401 Unauthorized with errorCode 1142 InvalidEmailOrPassword.
{
"code": 401,
"status": "Unauthorized",
"error": "InvalidEmailOrPassword",
"errorCode": 1142,
"errorMessage": "Invalid email address or password",
"CallBackTimeMS": 1017
}
I am still able register new players and sign in from within my game build, but cannot get successful response from documentation page or from alnternative REST client.
What am I doing wrong? Title ID is F8A4.
