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.

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

Getting a 400 bad request while doing a request payment in sandbox. with no further message and not sure why or what is wrong.

Hello,I am integrating my application with two APIs (Collection and Remittance)Collection API works ok, I can successfully call /requesttopay and receive callback after processing, but on Remittance collection I receive 400 over and over again. I have no idea why, because /requesttopay body and headers looks the same as in /transfer request. Any idea how to solve it ?My request  

Hello all,Below are a few challenging cases I encountered while in the production. Any help in any way will be of great help to many developers.  1I successully make a request to pay but I have a case where the user enters1.1) a wrong pin.1.2) a pin not exactly 5 digits as required. The end point does not return any error or response. Normally I would need to get that error or response and do something server end.How do I get around a case like this? Or is there a way to get that error message? I have already used    getRequestToPay/{X-referenceId} and it does not return anything in this case of a wrong pin. 2When a user cancels a transaction, I noticed that it still remains in status PENDING and when a user uses USSD, they can access the requestToPay awaiting their confirmation.I do not want this to happen. When a user cancels, the request should indeed be ended and not accessible any other way. how do i implement this. 3Lastly, How do i reduce the timeout time for requestToPay in the

How can the MoMo Open API be used to make bank transfers (both deposits and withdraws)?

Four months ago I completed a User Acceptance Test by demonstrating how the API Products(Disbursements and Collections) were integrated into our application. A followup email was sent saying “Kindly be informed that the team is aligning internally and will revert once completed. Thank you.”, but as of today not much has come of this even after I requested an update on the status of the Onboarding Stage.Requests to the Api Endpoints are no longer working and development on our application has stalled.How do I proceed?

Dear MTN MoMo team,Thank you for a great product. We are working on integration of the MoMo payment gateway into our App and wanted to ask about the following points:1. There is no API available for creating users.2. Regarding the 'ValidateAccountHolderStatus' API, where can I find the 'accountHolderIdType' and 'accountHolderId'?3. If a user is not registered and calls the 'GetBasicUserInfo' API, what error will be received? This is not specified in the API document.4. Will the 'RequesttoPay' API function in a way where, for example, the amount will be debited from the consumer (Payer) and credited to the Merchant's wallet?5. Will the 'RequestToWithdraw' API function in a way where, for example, the amount will be debited from the Merchant's wallet and credited to the consumer (Payer)? I am looking forward to hearing from you.All the bestBenjaminCARE Denmark
