API
Retrieve a contact
Addresses are stored lowercased and the lookup matches that way, so case in the path does not matter. The single-contact response also carries `audiences`, every list the contact is in.
GETapi.openemail.uk/contacts/{email}
Runs the real call against your workspace, with your own key.
GET /contacts/{email}
Addresses are stored lowercased and the lookup matches that way, so case in the path does not matter. The single-contact response also carries audiences, every list the contact is in.
