Getting "The initiator information is invalid." when Live about mpesa-api

[newtonmunene99]

Hi there, does this occur in the sandbox?
It doesn't seem to suggest a problem with the library, you might be passing the wrong initiator name.
When you say everything else works, does that include other methods which require initiator name?

The withdrawal works in postman but fails when i use the code with the same credentials

Any solution to this problem ?

Hi @cngeru i'm still unable to reproduce this. You mentioned it worked for you on Postman. Can you share your request, with dummy values for sensitive fields.

The request body in postman

{
    "InitiatorName": "CODE",
    "SecurityCredential": "CODE",
    "CommandID": "BusinessPayment",
    "Amount": "100",
    "PartyA": "CODE",
    "PartyB": "CODE",
    "Remarks": "CODEWithdrawal",
    "QueueTimeOutURL": "https://us-central1-CODE.cloudfunctions.net/mpesaWithdrawalTimeout?userId=xx&wAuth=xx",
    "ResultURL": "https://us-central1-CODE.cloudfunctions.net/mpesaWithdrawalResult?userId=xx&wAuth=xx",
    "Occasion": "CODE Withdrawal"
}

The code (JS)

const B2C_CREDS ={
  client_key: CODE,
  client_secret: 'CODE',
  initiator_password: "CODE",
  certificatepath: null
}

const B2C_DETAILS= {
  SHORTCODE : CODE,
  INITIATOR_NAME:'CODE',
};

const environment = "production";
const B2C = new Mpesa(B2C_CREDS, environment);

try {
    await B2C.b2c({
      Initiator:B2C_DETAILS.INITIATOR_NAME,
      Amount: amount,
      PartyA: B2C_DETAILS.SHORTCODE,
      PartyB: phoneNumber,
      QueueTimeOutURL:timeout,
      ResultURL: result,
      CommandID: "BusinessPayment",
      Occasion: `Withdrawal By ${CODE}`,
      Remarks: "CODE Withdrawal" 
    })
    .then((mpesaResponse)=>{
      console.log(JSON.stringify(mpesaResponse));
      return {result: 'Mpesa Transaction was successful'};
    })

@cngeru I'm still looking into this, in the meantime, I've added the option to pass security credentials when initiating. This means you can generate the security credential in your M-Pesa web portal and pass it statically as a string. The library will generate it automatically if you exclude this field or pass it as null.

Alrighty
