# Users

Some APIs require you to identify users, for example to set someone as a vendor admin. Furthermore, there are two different notions of "user" that are needed for different purposes, either

* Someone who is reachable by email (identified by account id). This always exists for a given email address.
* A profile that is part of the network (identified by a profile id). This may not exist.

## Look up by email

<mark style="color:green;">`POST`</mark> `https://talque.com/webhook/org/:orgId/profile/email-lookup`

Discover the account and profile id for a given email address. The profile id can be `null` if there is no profile.  In addition, basic user and profile data is returned.&#x20;

The input email is matched against the primary or an alias email of potentially existing users, in which case the returned account data will have the primary email address. The output `orgProfile` is only listed if the user is already participant of the network.
