Keep session after redirect to external site

[isendu-dev]

Hi there,

here my scenario: in the thank you page, I put a link to an external website (in a new tab - as per Shopify security policy, not in same tab) that I own where customers have to select something that will modify a property of the order just made; after the selection, customers are redirected back to the order status page, but the session is no longer on, so they are asked to login (which is not acceptable - and most customers are not logged in during the purchase).

Is there a way to maintain the session, using maybe some kind of url params to pass on frontend?

Any other ideas?

Thank you

We are facing similar problem. Did you find a solution to this? We want to redirect the user to Instagram's OAuth and then back to our app. However, we are unable to maintain the session and are redirected to login page as soon as we redirect from Instagram.
