Hello MTN MoMo Community,I'm successfully creating payment requests in production (getting HTTP 202 responses), but customers are not receiving any SMS notifications to authorize the payments.🔧 Current Setup:Environment: Production with live keys Country: Côte d'Ivoire API: Collections requesttopay endpoint Response: HTTP 202 (request created successfully)✅ What's Working:Authentication is successful Payment requests are created without errors API responses indicate success Using correct production URLs and target environment❌ The Issue:Customers receive no SMS notifications When customers dial the USSD code, they see "No pending transactions" Transactions appear to be created but not pushed to customer devices❓ My Questions:Are there specific payload parameters required to trigger SMS delivery? Do I need special headers beyond the standard ones for SMS notifications? Is there a separate SMS trigger API call required after requesttopay? Are there customer number validation requirement

I am consuming the MTN Open API and most of the endpoints worked except for some specific endpoints which I would enlist below;Kindly note that the response I receive from these are all BAD REQUEST so kindly help me out in determining what is the issue; Request to Pay:  POST https://sandbox.momodeveloper.mtn.com/collection/v1_0/requesttopayHeaders: X-Target-Environment X-Callback-Url        X-Reference-Id Ocp-Apim-Subscription-Key Authorization  Request Body: {"amount": "2.0","currency": "GH","externalId": "7916d515-ab40-4bba-bb67-b68bfb13b94c","payer": {"partyIdType": "MSISDN","partyId": "23354****414"},"payerMessage": "Kindly accept for payment of TEST","payeeNote": "Thanks for paying for Test"}   Disbursement / Transfer       POST: https://sandbox.momodeveloper.mtn.com/disbursement/v1_0/transfer       Headers:   X-Target-Environment   X-Callback-Url          X-Reference-Id   Ocp-Apim-Subscription-Key   Authorization Request Body: {"amount": "2.0","currency": "GH","externalId": "e4f7

I tried creating an api user in the postman by sending a post request on postman to this link https://sandbox.momodeveloper.mtn.com/v1_0/apiuser. The post request contained in my header X-Referene-Id(a random uuid generated by a uuid generator), Ocp—Apim-Subscription-Key(which is the primary key gotten after subsrcibing to a product, in my case I subsricbed to the collection widget producr) and Content-type(whose value was application/json). After doing all of this and sending the post request, I am getting a status code of 401 “saying Access Denied due to invalid subscription key. Make sure to provide a valid key for an active subscription”. I have confirmed multiple times that I use the primary key and i even tried out the secondary key but same thing, I have tried to open another account to subscribe to a new product, yet still the same thing. I will sincerely appreciate it if this can be attended to as soon as possible 

I trying to get an api subscription key for collection and disbursement subscribe page activates but can’t subscribe to any product what might be the issue?

Hi everyone,I'm currently in the process of integrating MTN MoMo API for a project under my company, Nyamora Petroleum and General Trading Co. Ltd (South Sudan registered), and I’d appreciate support or insights from anyone who has gone through this before.💳 1. Personal Bank Account Use for BusinessOur business would like to use a personal bank account (under my name – Riak Mawut Angui) to receive MoMo settlement payments temporarily.Has anyone done this before? Is it allowed under MTN’s onboarding policy? If yes, is a signed authorization letter from the board linking the personal account enough? 📝 2. Mandate Form ConfusionI'm the sole authorized person managing this project.Need help understanding: Can one person sign off on the Mandate Form? How should the passport photo be submitted – is digital okay or does it need to be manually endorsed? 📱 3. Mobile Number for MoMo APII plan to use my personal number as the MoMo line for OTPs and system access.Question: Can this one numbe

What are the countries where MoMo APIs are live ?

I successfully created it using/v1/0/apiuser/v1/0我使用/v1/0/apiuser/v1/0成功创建了它I successfully created it using/v1/0/apiuser/v1/0 apiuser, but using/V1_0/apiuser/{X-Reference Id} does not return any data for apiUser. Which API do I need to use to obtain apiUser? I can successfully obtain apiKey through/v1.0/apiuser/{X-Reference Id}/apikey  

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.

Hi!When I do a POST to the CreateAccessToken endpoint I get a response where the token_type has a value set to "access_token" instead of something like "Bearer". I’m expecting the token_type to be Bearer since the Transfer endpoint documentation states that the Authorization header should be the “Bearer Authentication Token generated using CreateAccessToken API Call”.Am I missing something?Any help/advice would be greatly appreciated!

Hello everyone,We are a French startup and we’d like to use the MoMo API in one of our solutions. We’d like to know if it’s possible to transfer CFA from Ivory Coast directly to a French bank account in Euros using the MoMo app. Has anyone already tried this, or does anyone have information on the steps and requirements involved? If it’s not directly possible, are there alternative methods or recommended services for sending money from Ivory Coast to France? Thank you in advance for your help!
