It is accessible over the mobile phone (or as a smartphone App)for both customers and merchants. With \u003Cstrong>MoMoPay\u003C\u002Fstrong>, merchants can sell airtime and earn commission, pay suppliers, pay salaries as well as transfer money to the bank.\u003C\u002Fp>\n\u003Cp>MTN has opened an API for the developers to create Apps for merchants to received payments.

You must know that these subscription keys are not for the Live usage. You will get the \u003Cstrong>Live\u003C\u002Fstrong> subscription keys on the other portal \u003Ca href=\"https:\u002F\u002Fmomoapi.mtn.com\" target=\"_blank\" rel=\"noopener\">momoapi.mtn.com\u003C\u002Fa>, there is no public signup here, you get the username\u002Fpassword from MTN directly, after KYC approval process (takes a while actually).\u003C\u002Fp>\n\u003Cp>Once you are in the Sandbox you must always keep in mind that you have certain differences from the Live MoMoPay system, the main are:\u003C\u002Fp>\n\u003Cul>\n\u003Cli>Sandbox \u003Cstrong>is not requesting real money\u003C\u002Fstrong>, so no USSD request on your phone. no matter how hard you try - Sandbox has an additional API to provision API user and access key.
