Recently got Multipass up and running, it's working great! I have a question about the return_to field that you can use to generate an encrypted Multipass login URL (for redirection).
The return_to field is working just fine, except when I add a query parameter. Our site involves a Shopify domain and a third party domain (hence the Multipass integration) so there will be times when we need to redirect the user to a URL that isn't part of the Shopify domain.
I though this would be no problem - just set up a custom Shopify page that parses a query parameter and does the redirection in JS, easy peasy. However, it looks like Multipass does not like having query params included in the return_to field. Without the params, the redirect works fine, WITH the params I get a Shopify "Oops!" error page with an error message: Invalid Return To URL. Please enter a valid URL.
So, is there a way to include query parameters in the return_to field? Or even better, is there a way to allow Multipass to redirect a user to a non-Shopify store domain?
Please let me know if any of this is unclear, or you need more information! Thanks all.
