Getting Your API Credentials

To use the MTN Momo Collections API, you need to generate your userId and userApiKey. Here's how you can generate them:

npx momo-sandbox --callback-host <callbackHost> --primary-key <primaryKey>

Replace <callbackHost> with the URL of your callback host and <primaryKey> with your actual MTN Mobile Money API primary or secondary key.

This command will generate a new user and display the userId and userApiKey in the console.

Note: "These credentials are specifically intended for use in the sandbox environment. In a production environment, you will be provided with the necessary credentials through the MTN OVA management dashboard after fulfilling the necessary KYC (Know Your Customer) requirements."

Installation

Use the package manager npm to install mtn-momo-api.

npm install mtn-momo-api --save

Usage

Here's an example of how you can use the MTN Momo Collections library in your project:

const { makeRequest } = require('mtn-momo-api');

makeRequest({
  callbackHost: '<callbackHost>',
  userApiKey: '<userApiKey>',
  userId: '<userId>',
  primaryKey: '<primaryKey>',
  amount: '<amount>',
  currency: '<currency>',
  externalId: '<externalId>',
  partyIdType: '<partyIdType>',
  partyId: '<partyId>',
  payerMessage: '<payerMessage>',
  payeeNote: '<payeeNote>'
})
  .then(({ response, status }) => {
    console.log('Response:', response);
    console.log('Transaction Status:', status);
  })
  .catch(error => {
    console.error('Error:', error);
  });
