Hi Florian, can you provide some clarification on exactly what you need? Here's what you can do right now in the REST API: Given an email address, you can get a list of all that's address's memberships. You get a sequence of member entries, and from each of these you can find its mailing list, role, and member id. So while you'd still have to do a search, it should be of a much smaller set. Note that to identify a "membership", you need the triplet of address- or-user[*], mailing list, and role. [*] You can now provide a user as long as the user has a preferred address. -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/799612 Title: Expose REST API call to look up member/user id given an email address To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/799612/+subscriptions

http://.../members/find now supports POSTing with - email address (required) - fqdn listname (optional) - MemberRole (optional) which can be used to find memberships. Returns a collection of member records. ** Changed in: mailman Status: In Progress => Fix Committed -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/799612 Title: Expose REST API call to look up member/user id given an email address To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/799612/+subscriptions
