Connect Telegram Ads

You need Chrome, a Telemetrio account and access to the API page for your Telegram Ads account. Your advertising connection and AI-client authorization are separate steps.

Install the extension

1. Download TG Ads Assistant — Connections Dev 1.7.4.
2. Extract the archive into a folder you will keep on your computer.
3. Open chrome://extensions, enable Developer mode, choose Load unpacked, and select the folder containing manifest.json.
4. Pin the extension. The dev package uses stable ID ifcgdnhjomlkcicjiijpkcjhmednngca.

To update an existing installation, replace the files in the same extracted folder and click Reload in chrome://extensions. Confirm version 1.7.4, then refresh every open Telegram Ads tab and reopen the extension workspace. Existing settings and the device session are preserved. The archive is a development package, not a Chrome Web Store listing. Older videos describe the previous cookie-based interface and are not setup instructions for this release.

Sign in and transfer your key

1. Open the intended account on Telegram Ads → API. Click Connect MCP in the Telemetrio card beside the native API form, or use the compact menu in the header.
2. Sign in to Telemetrio. Confirm the displayed Telemetrio user before continuing.
3. Choose Continue with this account, review the actual Telegram Ads account ID, enter a connection name, and explicitly confirm transfer of its official API token. The checkbox starts unchecked.
4. The extension sends the token directly to the Ads service. The service verifies that the token belongs to the displayed account, then stores it encrypted.

The provider token is never saved in extension storage, placed in a URL, sent to analytics, or passed to the AI client. It is not read until confirmation. A different selected Ads account cannot silently reuse the previous account's token. The extension does not create or revoke Telegram API tokens.

Authorize an AI client

A successful key upload means the advertising account is connected. It does not authorize an AI client yet.

Choose Connect MCP in the extension and copy https://api.tlmtr.dev/mcp/ads. Add this remote MCP server in your AI client. Its authorization flow opens Telemetrio: sign in and select the exact accounts and Read-only, Manage advertising or Manage budgets permissions for that client. Newly added connections are excluded until separately authorized. Manage advertising connections and individual AI authorizations independently in Telemetrio.

Interface preview

These screenshots show the installed 1.7.4 extension with synthetic test data.

The header identifies Telemetrio and shows Telegram Ads connectivity and AI access separately. All extension screens use English. The same navigation appears on every page: Overview, Accounts & AI access, Connect MCP, and Settings. The API server remains editable under Settings → Advanced settings. Ad checks and promotional sections are hidden in this version; existing connection settings and saved drafts are preserved.

Read-only appears only when no write rights are granted. With management rights, the read label is Read & analyze. Related-account rights never widen the root account; unavailable or incomplete access metadata is shown explicitly.

Status and recovery

Situation	Next step
Key expired or revoked by Telegram	Open the intended Ads API page and choose Update key
Temporary network or provider error	Keep the saved connection and retry; review its last successful check time
Account mismatch	Switch to the intended Ads account before transferring its key
Legacy cookie connection	Explicitly transfer an official API token
Extension session expired	Sign in to Telemetrio again; server connections remain
Stop one AI client	Revoke its authorization in Telemetrio
Disconnect an Ads account	Remove the saved token; all grants lose access to that connection

Closing the popup or restarting Chrome preserves trusted local settings and the extension's own device session. Logout revokes only that session. Disconnecting locally does not revoke the token at Telegram.

Hidden tools

Ad checks and promotional materials are hidden in extension 1.7.4. Earlier guides and videos show the previous interface; saved drafts are retained. MCP supports scoped reads, advertising changes and budget operations only for the exact account permissions separately approved for each client.

See authentication, MCP tools and coverage for the exact boundaries. Dev deployment and a new archive's installation smoke must be verified before treating a release as delivered.
