Your HTTP module is returning an error. Check what that error is, I suspect it will provide a clue. ---

The error module has reported the following error; “The operation failed with an error. Validation failed for 1 parameter(s).” ---

That sounds like your JSON may be malformed. Check the input bundle of the webhook module. Copy the received JSON and paste it into an online validator such as [jsonlint](https://jsonlint.com/) ---

Thank you so much I just tried it but the validator has returned result is valid ![Screenshot (2022)](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/e/2/e2138e9564dc60d1b59aafd08bec52b30cd18c5c.png) ---

oh wait. I see the problem. In your HTTP module, you are sending the JSON in the Header. It should be in the Body. Also, assuming that ~~Paynow~~ Payhere requires a JSON body, then it needs to be sent as a valid JSON payload, rather that a concatenated list of parameters (which is what you have now). I’m pretty sure Bob Pettito has a Paynow tutorial somewhere. Check his Youtube channel. ---

Thank you @ThinhDinh as well I’ll also take time to go through the documentation for PayNow as it seems the videos are for a different payment gateway from PayNow ---
