Sandbox test completion inquiry

Hello team. I have partially completed the tests. I am filling them in a excel sheet. on the link.https://docs.google.com/spreadsheets/d/1LPYxZM26xVOYzSyUHdfiK7LAizrnB6j4JzB2iXdUqC0/edit?usp=sharing I am confused about a few though, like; •⁠  ⁠Duplicate Reference ID (requestToPay and Transfer): I am also getting 202 accepted. for this I thought it would fail.•⁠  ⁠⁠Exceed Daily Limit(requestToPay): Confused on how I can test this. I dint see any number for this case.•⁠  ⁠⁠Invalid AccountHolderType(active and ): this I understand they mean msisdn, but I dont see anywhere to vary it. they ate all get requests without any body•⁠  ⁠⁠Invalid AccountHolderID(ValidateAccount and Balance): Same issue as above.

Signing in error

Greetings, I am a new user here. I have signed up for the MoMo developer and yet to subscribe for a product. When I try to Sign in, it gives an error that...”Please provide a valid email and password.”. Thinking I didn’t sign up well, when I try to Sign Up again it tells me ”User with specified identity already exists”.Thinking password was not correct, I requested to change “Forgot password” and it allowed me to change through my email.How do I sign in?

Which MOMO API website should we be using

I’ve been using https://momodeveloper.mtn.com/ and recently I came accross https://momoapi.mtn.com/And generally they do the exact things, except you’ll have to create a new account, which I did but they are taking too long to approve my product(Collections and Disbursement) subscriptions which makes me wonder if the site is still operational.Any answers will be much appriciated. Thanks.
