# Letsignit + Lutril: setup guide

> Lutril connects to Letsignit with a Public API key so it can see who holds an email signature account, create one when access is granted, and remove it when it is not needed. Create the key from the API page in Letsignit's settings and paste it into Lutril.

## Setup

1. Sign in to the Letsignit console at cloud.letsignit.com as an administrator of your Microsoft 365 tenant.
2. Open Settings, then the API page.
3. Select Create an API Key, give it a name, and choose the Public APIs scope. The SCIM and On Premise scopes will not work: they are different APIs.
4. Click Create, then copy the secret key straight away. Letsignit shows it once and never again.
5. In Lutril, connect Letsignit and paste the key into the Public API Key field.
6. Optionally set Email domains to narrow which of your directory addresses Lutril checks against Letsignit, for example acme.com,acme.fr.
