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.

what is the collection widget about

I have been looking through the documentation and can’t find much information about the collection widget product. All I could find is that it enables a developer or partner to integrate a MoMoPay checkout button to accept Mobile Money payments on your e-commerce site. but what differentiates it from the othe collections product and how can we implement it in the sand box.

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.

How can the API allow person to person transfers?

Hello 🤗I want to implement the scenarios bellow, can you suggest for me the right endpoints:Transfer money from user account to his friend. Transfer money from user account to business accounts of some service providers (to pay a bill or any another service).I want to use CreateInvoice for both of cases, will it work? because the friend account is not for business, will this provide and error? does mtn make a difference between a merchant or a personal account?and what endpoints do you suggest for me.@byaruhaf @anicet @crankluga @allan.ddamulira @leontymo I would appreciate if you help me 🙏

GetAccountBalance Endoint

Good day team,I am completing the UAT test cases excel document for Collection. I have all other cases completed except the one for insufficient funds, i.e. sending a debit amount greater than Payer available balance. Because I do not know the balance I have, I decided to call the GetAccountBanlance end point. Unfortunately I am getting status 500 (internal server error), with the message “Authorization failed. Insufficient permissions.”Any assistance to point me to what I am not doing right.Thanks
