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

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
