How to Determine Your Tenant Prefix for the Letterhead Browser Extension

Overview

When you install and use the Letterhead browser extension, you’ll be prompted to enter your tenant prefix before signing in. This article explains how to locate your tenant prefix from the Letterhead web app URL.

Determining Your Tenant Prefix

Follow these steps to find your tenant prefix:

1. Open the Letterhead web app: Navigate to Letterhead in your browser and sign in if needed. Once loaded, look at the URL in the address bar.
2. Inspect the URL structure: The tenant prefix is derived from the subdomain (if any) before app.tryletterhead.com. Evaluate which pattern applies

Pattern 1: When there’s no prefix before “app”:

• The web app URL begins with:https://app.tryletterhead.com/...
• In this case, your tenant prefix is lh1.

Example:
https://app.tryletterhead.com/organizations/black-bitter-coffee-brand/channels/black-bitter-matcha-times

In the example above the tenant prefix = lh1

Pattern 2: When there’s a prefix before “app”:

• The web app URL begins with:https://<prefix>.app.tryletterhead.com/...
• In this case, <prefix> is your tenant prefix.

Example 1:

https://abc.app.tryletterhead.com/organizations/… In the example 1 above the tenant prefix = abc

Example 2:

https://xyz.app.tryletterhead.com/organizations/…

In the example 2 above the tenant prefix = xyz

ℹ️ Note

Confirm you’re signed in to the correct account in the web app and verify the subdomain exactly as shown in your browser’s address bar.
