Good Day @Harvey I hope you’re well. I’m kindly seeking your assistance with the error : “status=Error&error=Invalid+Hash.++Hash+should+start+with%3a+6CB30F” when attempting to make a test mobile express transaction in Postman. I’ve tried all your suggestions up until this point but the error persists. The link to your collection has expired . Please may you kindly assist with a new one or further guidance on the resolution .
