In the iDEAL TransactionResponse, an IssuerAuthenticationURL
is provided to you to which you should redirect the user to. This URL will lead the user to the banking pages (browser or mobile app) in which the user can authenticate the iDEAL payment.
These IssuerAuthenticationURL
contain parameters seperated by an "&" or "&". The IssuerAuthenticationURL
looks something like this: https://www.issuingbank.eu/ideal?random=1Y98dHjPwe2qq3s&trxid=0001000000000001
It is important that the provided URL is used for the redirect without adjusting any of the content! This includes any encoding of the URL before using it for the redirect, as this may break the URL (parameters).
