No response from callback url

[kamandemwangi]

I am interacting with lipa na M-pesa online endpoint, https://sandbox.safaricom.co.ke/mpesa/stkpush/v1/processrequest. I am experiencing an issues where sometimes I get response at my callback url but sometime there is no response at all and my callback url is accessible from the internet.

For me also same issue with sandbox api. sometimes getting the below response, most of the times, no response.
stkCallback: {
MerchantRequestID: '53785-65856915-1',
CheckoutRequestID: 'ws_CO_23052022122137653708374149',
ResultCode: 1019,
ResultDesc: 'Transaction has expired'
}

@mossey please give as an explanation or a solution to the issue. I rely on the data posted to the callback url for systems functionality.
@sandeshdasi Besides lack of response, what you are getting means an error occurred or the transaction failed as per the Safaricom daraja documentation "ResultCode: This is a numeric status code that indicates the status of the transaction processing. 0 means successful processing and any other code means an error occurred or the transaction failed."

@kamandemwangi thanks for the response. I tried with LIVE details instead of SANDBOX, it is working fine, getting valid response every time.

I am simulating a C2B transaction on sandbox. The following are the steps I have taken:

1. Get auth token.
2. Register Callback URLs
3. Simulate payment.
   All the above are successful.

However the callback URL is not getting any hits. It is not a UFW issue cause another STK callback script running (m-pesa live) is getting hits of the callback.

What could I be missing here?

am also getting this issue on sandbox,Everything is happening correctly and the payment are being made successfull but my callback is not getting any hit at all from mpesa

[ronjohnson-owuor]

really urgent someone please

This is an issue from safaricom's side. It has been bothering so many people for so long. It is really sad to see that 2 years later nothing has been done to fix it.

works for me

Who has been able to get the data in the callback url using asp.net? I still cannot get data to be saved in my database when live

Hello , Try using alternatives of ngrok like localtunnel works for me

Had the same issue with NodeJS and switching to localtunnel sorted it out on the Sandbox API.

I have the same issue , it seems the sandbox has an issue calling the callback url

Getting no response at my callback since 23rd August. stk push and payment is successful but no response from https://api.safaricom.co.ke/mpesa/stkpush/v1/processrequest. My environment hasn't changed. What could be the issue?

[kelwinsj]

It appears that this issue could still be active as I am also not getting any hits at the callbackURL. I am running some automations and hence cannot setup Ngrok in this case.

Hope this gets fixed soon-er. Otherwise, I may have to now add a query on top of my flow to check transaction status which shouldn't be necessary if this was working alright!

Update: I was able to get the callback URL to work. I just needed to register it first as Safaricom will not send a response to a callback URL that is not registered.
