S2member redirecting webhook intended for another plugin

I use s2member pro for membership management for an association. Recently, we’ve started taking donations from members on our website for a current project. For that, I’m using a different plugin called WP Full Stripe. Communications from stripe to the webhook for that new plugin are being redirected by s2member.

The webhook which WP Full Stripe wishes to call is https://albertacrownattorneys.ca/wp-admin/admin-post.php?action=handle_wpfs_event&auth_token=* (I replaced the actual token with a wildcard).

Calls to that address return HTTP status code 302 and redirect to https://albertacrownattorneys.ca/member-news/.

Is there some way that I can prevent the redirect of this webhook?

Thanks!
