Getting Started

Before installing the Gmail Add-in:

  1. Your organization must have the Matter Planner add-on enabled on your Athenty account. Check under Settings → Billing or contact your account admin.
  2. You must be logged in to the Athenty admin portal as a user with at least Member role.
  3. Your Gmail account must be a Google Workspace account (business or education). Personal @gmail.com accounts are not supported by the Google Workspace Add-on platform.

Each installation requires a one-time 6-digit pairing code.

  1. Log in to app.athenty.com.
  2. Go to Settings → General.
  3. Scroll to the Matter Planner Add-ins section.
  4. Click Pair Gmail Add-In — a 6-digit code appears with a 5-minute countdown.

Keep this tab open. You will enter the code in Step 3.


Note: The Athenty Matter Planner Gmail Add-in may not yet be publicly listed on the Google Workspace Marketplace. If you do not find it there, use the early access option below.

  1. Go to the Google Workspace Marketplace.
  2. Search for Athenty Matter Planner.
  3. Click Install and follow the Google authorization prompts.
  4. Grant the requested permissions: message metadata, message read access, and script execution.

During the early access period, your Athenty account manager will provide a direct installation link.

  1. Click the installation link provided by your Athenty contact.
  2. Review and accept the Google OAuth permission prompt.
  3. The add-on installs to your Google account.
  4. Open Gmail — the Athenty Matter Planner icon appears in the right sidebar.

Contact us at athenty.com/contact to request early access if you have not already received a link.


Step 3 — Pair the Add-on with Your Account

Section titled “Step 3 — Pair the Add-on with Your Account”
  1. Open any email in Gmail.
  2. Click the Athenty Matter Planner icon in the Gmail right sidebar (it looks like the Athenty logo).
  3. A card prompts you to enter your 6-digit pairing code.
  4. Enter the code you generated in Step 1.
  5. The card confirms your organization name and your name.

The add-on is now paired. It uses this session going forward and refreshes its token automatically.


Because this is a Google Workspace Add-on (not a Chrome extension), it is also available in Gmail for Android and iOS automatically once installed.

  1. Open the Gmail app on your phone.
  2. Open any email.
  3. Tap the Athenty Matter Planner icon in the email action bar (you may need to tap the overflow “more” button to find it the first time).
  4. The Athenty card renders in the Gmail sidebar panel.
  5. If this is the first time on this device, you will be prompted to enter a pairing code — generate one from your Athenty dashboard.

Go to Settings → General → Matter Planner Add-ins in your Athenty dashboard to see all currently paired sessions, including channel (outlook, gmail, snap) and last-used date.

To remove access for your Gmail add-on session:

  1. Go to Settings → General → Matter Planner Add-ins.
  2. Find the entry labelled Gmail Add-in.
  3. Click Revoke.

The next time the add-on loads, it returns to the pairing screen.

  1. Open any email in Gmail so the Athenty sidebar card loads.
  2. Tap the Settings icon (gear) in the card header.
  3. Tap Sign out.

The add-on icon does not appear in the Gmail sidebar. Wait a few minutes after installation for Google to propagate the add-on. If it still does not appear, try reloading Gmail. On mobile, close and reopen the Gmail app.

“Session expired. Please re-pair.” Your refresh token has expired or been revoked. Generate a new pairing code in Settings → General → Matter Planner Add-ins and enter it in the add-on pairing card.

“Upgrade required” appears instead of the matter picker. Matter Planner is not enabled on your organization’s plan. Go to athenty.com/pricing or contact your admin.

The pairing code says “Invalid or expired”. Pairing codes expire after 5 minutes. Return to Settings → General → Matter Planner Add-ins in your dashboard and generate a new code.
