eMagazines provides Immediate Issue links that can be shared with your new subscribers via email or as a link off of an order confirmation page. But note, these links are open to the public. So they can get shared around. Please do not post online without some type of "gate".
Using the API to get your customer started with the first issue of their magazine is the preference. It's the most secure way to distribute the magazine publishers content and it gets your subscriber an email (or a link) to their first issue without having to enter additional information or complete another form.
The API is extremely easy to use. If your tech team has any questions or would like assistance getting set up, please reach out and we'll help.
