MoMo API Sand Box Q&A

Hey, does momopay reference support abc alphabet like 123abc amd secondly can we a momopay staging account before getting a real one?

Hi, for I client I need to integrate the MTN Momo payment api. A company/cooperative wants to pay its suppliers (farmers) to their mobile numbers. I have seen the api docs, can create tokens, check balance etc in the sandbox environment. When the user is created a callback url can be registered. According to the docs the callback is used for the transfer endpoint. I was advised by others to use the ‘deposit’ endpoint to send money to the farmers ( https://sandbox.momodeveloper.mtn.com/disbursement/v1_0/deposit ). But then would need calls to https://sandbox.momodeveloper.mtn.com/disbursement/v1_0/deposit/ to check the status. I cannot find info regarding this endpoint in the documentation, not sure if this is what I need to send money from a cooperative to its farmers mobile. I prefer using a callback instead to receive the status update. Question, can the deposit endpoint work with a callback? Or if not, is there another endpoint that I should use to be able to send mobile money from

A few days ago, creating a payUrl to get a payment QR code went very well, however, today when testing the payment function again, even though there was no error during the order creation process and when checking the transaction status, the order still exists, but my payUrl is displayed as in the picture below, why is that?

Hi Team, We are building a ride-hailing app for the country of Ivory Coast. For the same, we are trying to integrate MTN money API into our mobile app which will allow drivers to request ride money from the riders. We are trying to setup a sandbox environment to test the APIs but are unable to do so. It would be great if someone from your developer team can help us with our queries over a call or we can put together our questions in an email for your team to answer. Regards
