MoMo API Sand Box Q&A

Hello MTN great community,I want to see if my mtn transactions are really working, does mtn offer a platform were we can log into virtual mtn account and see if the money has been transferred successfully ? or is there any methods to get this information.Thank you.

When is oauth2 Token used? 

Can the sandbox API be tested on a application? When I send a call to the requesttopay endpoint I get a server error. Secondly collection widget display but doesn’t work and when I tried to create Oauth 2.0 token I get Authorized as status code and error of “invalid client”. I also want to know how I can place the API user key and API key on the authorization field after encoding to base64.

Hello,It’s. my first time to use the momo api. I am trying to create a user in sandbox using firebase authentication trigger function. I subscribed for collections widget and am passing its primary key as the Ocp-Apim-Subscription-Key.the user is being created successfully when i run in the sandbox but returns access denied when i execute the code.import * as admin from "firebase-admin";import * as functions from "firebase-functions";import { v4 as uuid4 } from "uuid";export const createUser = functions.auth.user().onCreate(async (user) => { const uid: string = user?.uid; const myUUID = uuid4(); const key = functions.config().primarycollection.key; console.log(myUUID); try { await admin.firestore().collection('users').doc().set({ userId: uid, myUUID, createdAt: user.metadata.creationTime, }); const provideUser = await fetch("https://sandbox.momodeveloper.mtn.com/v1_0/apiuser", { method: "POST",

this was a duplicate and i haven’t figured out how to delete yet. sorry 

I get CORS Policy error each time I try to make a request with the JavaScript fetch API to any of the sandbox endpoints but it works on the sandbox page

Hello Team, Hope you are doing well. I read through the MTN MoMo Open API sandbox documention but I can’t find the cancel preapproval endpoint. I can create and check the status of the preapprovals. Your help will be appreciated.Thank you

I downloaded the postman collection of APIs. However, in the variables, the consent request id is already defined. I was wondering how it is generated in the testing sandbox. I want to use it when creating an Oauth2 token which I later use in other endpoints that require it.
