Google Meet vs Microsoft Teams API for Meeting Bots: A Developer's Comparison

Two very different approaches to meeting APIs

Google Meet and Microsoft Teams both support third-party meeting bots, but they've taken completely different architectural approaches. Understanding the differences will save you significant debugging time — and will affect which platform you prioritise if you're building a new integration.

The short version: Teams has a more structured, officially-supported bot framework. Meet is more permissive but less documented. Both have quirks that will surprise you.

Google Meet: the browser emulation model

Google Meet doesn't have a native bot API. Third-party bots work by emulating a browser — launching a headless Chromium instance, navigating to the meeting URL, and interacting with the Meet web interface.

This has significant implications:

Admission works like a human guest. The bot needs to "knock" — it sends a join request, and the meeting host sees a notification like "Notetaker is asking to join." If the host has set the meeting to "admit all," the bot joins immediately. If the meeting requires host approval, a human needs to click "Admit."

This is a real UX friction point for automated workflows. Your product needs to either: - Instruct users to set their meetings to "admit all" or "trusted organisations" - Build UX around the knock flow (e.g., show a "pending admission" state with an instruction) - Use Google Meet's direct joining for meetings created by your own Google Workspace integration

The bot looks like a participant. Meet shows the bot in the participant list with whatever name you give it. This is good for transparency — everyone can see the bot is there — but it means users in sensitive meetings need a way to exclude the bot.

Audio quality depends on WebRTC negotiation. The bot captures audio over WebRTC, which means audio quality is subject to the same codec negotiation, network adaptation, and packet loss that affects human participants. In low-bandwidth conditions, transcript quality degrades.

API stability risk: Because the bot works by emulating a browser, Google UI changes can break integrations. This has happened historically. APIs built on top of this (like Gregnote) maintain compatibility by keeping up with Meet's changes.

Microsoft Teams: the official bot framework

Teams has a fully documented, officially supported bot framework with Azure App Service backing. Bots are registered as Azure applications, given API permissions, and added to meetings via the Teams API.

The integration is more complex to set up. You need an Azure account, an App Registration, a bot manifest, specific permissions grants, and (for production) a verified publisher status to avoid security warnings when users add your bot to their organisation. First-time setup takes hours, not minutes.

Once set up, admission is smoother. A Teams bot that's been added to an organisation's tenant can join meetings without host approval — it appears as a bot (distinct from human participants) and the join is automatic.

Audio is delivered differently. Teams bots receive audio via Microsoft's Graph API media streams — a completely different mechanism from WebRTC. The audio quality and latency characteristics are different, and the API for accessing it requires a specific set of Azure permissions.

Official support has real value. When Google changes the Meet web UI, third-party bots break silently. When Microsoft changes the Teams bot API, they publish migration guides and deprecation timelines. The stability trade-off is real.

Platform matrix for developers

Which to prioritise?

For a consumer or SMB product: start with Google Meet. The setup is faster, most SMBs use Google Workspace, and you can get to a working demo in an afternoon.

For an enterprise product targeting Fortune 500 companies: Teams is higher priority. Large enterprises are more likely to be Microsoft shops, and IT departments are more comfortable approving a registered Azure application than a headless browser. The setup overhead is a one-time cost.

For a product that needs both: use an abstraction layer (like Gregnote) that handles both platforms behind a single API. You don't want to maintain two separate integration paths — the operational overhead isn't worth it.

Zoom: the third platform

Zoom deserves a mention. Zoom's API policy has historically been more restrictive for third-party bots — the Zoom Apps framework has gone through several revisions, and the developer experience has been inconsistent.

The developer sentiment in the meeting bot space has shifted toward "Meet and Teams are reliable, Zoom is variable." That said, Zoom remains the default for some enterprise use cases (financial services, healthcare) and is worth considering if your target market uses it heavily.

Using Gregnote for platform abstraction

If you're building a product that needs to support multiple platforms, the most practical approach is to use an API like Gregnote that abstracts over the platform differences. You get a single API call:

POST https://api.gregnote.com/v1/bots
{
  "meeting_url": "https://meet.google.com/abc-xyz" // or a Teams link
}

And Gregnote handles the platform-specific admission, audio capture, and transcript delivery. The webhook payload format is identical regardless of platform.
