Hi,
I am trying to initiate an Express checkout request from the postman and encountering the following error.

Getting Invalid Id error.

content-type:“application/javascript”

I have testing hash and gone through the link provided by Team Paynow Invalid Hash When Initiating a RemoteTransaction - #20 by Mr_D

Looking forward for your response.

Best Regards

gourav · January 10, 2020, 9:30am

Going through the steps of generating the Hash is for plarforms and frameworks we have not build SDKs for. We have a PHP Guide on the developer page. Did you have a look at it?
