I have handled the issue by json decoding the $body response and then access the properties of $body as normal php arrays… And it working perfectly fine… But meanwhile the getInvoicePaymentMadeEventData does not exists in the $body response data but in your doc I saw that the the data attribute of the $body response data is of the object getInvoicePaymentMadeEventData but I don’t know is if the data attribute of the $body response must be accessed by calling the getInvoicePaymentMadeEventData object… That’s why I said initially that I am feeling there is something I an not accessing properly… Thanks
