Get contact id by email?

Hello,

How can i get a contact id by email? i am using rest api v1, i dont see such functionality, am i missing something?

thank you

The List Contacts query has a filter that can be applied as ?email=xyz@site.com.

the url would be /v1/contacts?email=xyz@site.com ?
or it needs to be passed as a parameter

ok that worked, thanks

can i apply multiple tags to multiple contact ids?

You can apply multiple Tags to a Contact or apply multiple Contacts to a Tag, but there is no method for doing both at once (and would violate RESTful design principles, given how the resource paths are laid out)
