iSignThis
Postbacksβ
iSignThis restricts Postback notification URLs to end with /v1/notification.
To work around this constraint /0/?foo=/v1/notification shall be appended to the given notification URL.
For instance, if the current notification URL is https://gateway.ixopay.com/postback/CO-0000-0000-0000-0000-0000-0000,
then iSignThis should receive https://gateway.ixopay.com/postback/CO-0000-0000-0000-0000-0000-0000/0/?foo=/v1/notification.
