How Should i Use my Collections API

So I want to use Collections and Disbursement APIs. I want to include them in my School Data Management System(SDMS) in Uganda. And my Question is, I have several schools Using my System, So the parents will be paying School Fees directly through the System. Should that money first go through my phone (Using the Collections API) such that i pick my commission and there after my phone sends it to the respective Schools (Using Disbursement). I really need to know how am going to handle this.Someone guide me on what is required.

Sandbox RequestToPay | 400 Bad Request Error

These are the steps I follow, I have created a collection product and I have my primary and secondary subscription keys.First step was to create an API user when was successful Second step, i created an API key for the API user which was successful. Third step, I created an access token for the user under the collections product subscription. Fourth step, I initiated the requestToPay request but it keeps failing with a 400 Bad Request. Is this an issue currently with the system (going by the error, it is not) or is it specific to me?

What parameters are required to trigger SMS notifications to customers in production?

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

Hi @all,I configured a user and api key. The call works (requesttopay), but the callback is not executed.I added the host dev.domain.com.xyHeader param for callback is “http://dev.domain.com.xy/webhook/mtnmomo”.No callback.Creating another user with callback domain “domain.com” it works…Any issues with “uncommon” domainnames?

HELP!!! I’m unable to create an API USER

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

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.

Sandbox access token invalid token_type?

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!

Transferring CFA from MoMo to a French bank

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!
