Send money to mobile number with callback

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 the

Cannot access momo's payUrl

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?

money API

 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

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.

Which MOMO API website should we be using

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.
