I want to download the information of customers who changed their subscription options (using the unsubscribe link in the footer of the email) and update my database for updating information on my website. I have a question with regards to the same.
How do I reflect the unsubscription/subscription opted by the user real time on my website or that has to be a bacthwise update (downloading the complete list of customer who changes thier subscription options).
Please let me know.
We currently do not offer a Bulk Activity API for exporting only updated users. What we do offer for managing subscriptions is a query option on the Contacts Collection REST API. You can find out more information on how this works here.
