Good morning @Gadgetgenie

Please ensure that your Integration ID and Integration Key are correct. If you are not using one of Paynow’s SDKs to initiate a transaction to Paynow, kindly make sure your Hash generation code is correct.

Here is how to do it

I highly recommend that you use the existing SDKs for integration to Paynow. Kindly share what tech stack are you using.
