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.

I am using mtn momo for e wallet system, there is two product one is collection to collect the money from customer and disbursement to send money to customer, I want to know the balance in the collection product also available to disbursement?

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 🙏

Hello @everyone! What product should I use to transfer money between 2 users in My Application? Please

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

I just saw a video on how to use the Momo OpenAPI but there is no documentation on the momo page. Can i get access to the implementation in the various languages, especially Javascript
