For a more secure option, you can provide a S2S URL for completes and reconciliations/reversals.
Completes Callback
The callback will fire only when a respondent completes the survey. The Parameters appended to the callback depend on those you select in the entry link or as optional parameters to included for completed surveys
Example URL
The CPI value can only be returned for completes when using a S2S callback, and will not be appended in the completes redirect link
If you’ve added a Hashkey, this will return appended as “&asr_s_hash=”
Reconciliation/Reversal Callback
You can define a Postback URL for the following 2 scenarios:
A user status gets changed from a complete to a non complete
A user status gets changed from a non complete to a complete
Information Returned
The URL will pass back the following info:
The CPI value
Session ID
Old status
New Status
Example URL
http://test.com/completetononcomplete?ps_rstatus=33&oldStatus=21&supSid=12345678&supCpi=1.20&ps_s_hash=123abc456def91011xyz
