It is possible to update the respondent's data in the recipient database in order to block their address for repeated mailings. A webhook is a URL requested using another IT system or opened in an ordinary browser.
The form of the URL is as follows:
https://www.startquestion.com/webhooks/[id_account]/[webhook_key]/[webhook_auth]/unsubscribe?additional_parameters
Additional parameters are as follows:
email - email address that you block on a given account.
No more parameters are needed. Because you are blocking sending of emails for this account.
An example form of a URL with additional parameters sent as GET is:
https://www.startquestion.com/webhooks/387487/TUwNjNDg3M/84b750d6956f02503015938fc38bfe36/unsubscribe?email=a.kowalski@webankieta.pl
If the email address is correctly unsubscribed from the mailing, you will receive the following message:
{"type":"success","msg":"E-mail has been unsubscribed"}
Note!
If you enter an incorrect email address, you will receive an error (invalid e-mail address).
However, when the email address has been added to the blocked addresses, you will receive a message (e-mail has been unsubscribed)
