 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

Hello team. I have partially completed the tests.

I dint see any number for this case.•⁠  ⁠⁠Invalid AccountHolderType(active and ): this I understand they mean msisdn, but I dont see anywhere to vary it. they ate all get requests without any body•⁠  ⁠⁠Invalid AccountHolderID(ValidateAccount and Balance): Same issue as above.

I am getting some response as string(0) ""public function requestToPay() { $url = "https://sandbox.momodeveloper.mtn.com/collection/v1_0/requesttopay"; $curl = curl_init($url); curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST"); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); # Request headers https://mysite.com $headers = array( 'Authorization: '.$this->createAccessToken(), 'X-Callback-Url: mysite.com', 'X-Reference-Id: '.$this->getGUID(), 'X-Target-Environment: sandbox', 'Content-Type: application/json', 'Cache-Control: no-cache', 'Ocp-Apim-Subscription-Key: *******'); curl_setopt($curl, CURLOPT_HTTPHEADER, $headers); # Request body 024

How do I access an api that uses merchant codes to push  payments from clients to business?

And created user via “/v1_0/apiuser” with “Ocp-Apim-Subscription-Key” header value = subscribed collections primary key with body:{"providerCallbackHost": "our-company-domain-host"} // without scheme4. Created userKey via “/v1_0/apiuser/{userId}” with the same “Ocp-Apim-Subscription-Key” header5. Created accessToken via “/collection/token/”6. Requested “/collection/v1_0/requesttopay” with headers:Ocp-Apim-Subscription-Key: profile->subscribed collections primary keyX-Reference-Id: f0b06fb7-4e7c-462b-9e29-d62b6b2f17cdX-Target-Environment: sandboxX-Callback-Url: http://our-company-domain-host/momo/p

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.
