How to monetize as developer

1- Does MTN pay commissions for transactions such as in collections and disbursements to the developer on their accounts? Revenue generation is important for any platform to grow.2-Is it in line with MTN policies to charge users for rendering certain services with the MoMo API? And if so, are there guidelines for the rates or tarifs? Let me hear from experts here.

Sandbox API Testing

Can the sandbox API be tested on a application? When I send a call to the requesttopay endpoint I get a server error. Secondly collection widget display but doesn’t work and when I tried to create Oauth 2.0 token I get Authorized as status code and error of “invalid client”. I also want to know how I can place the API user key and API key on the authorization field after encoding to base64.

How do I generate the Consent Auth Request ID used in the CreateOauth2Token endpoint?

I downloaded the postman collection of APIs. However, in the variables, the consent request id is already defined. I was wondering how it is generated in the testing sandbox. I want to use it when creating an Oauth2 token which I later use in other endpoints that require it.
