what is Client side certificate in paytm payment gateway integration? they are mentioning that it should be inclueded in raw folder. where can I get the Client side certificate?
FYI : Client side certificate is not included even in the sample paytm integration app
You can pass it as null. It's mentioned in the doc also
inCertificate is the Object which is holding Certificate Information. Pass this as null if no client certificate is used by the merchant (as given above in the Prerequisites section)
