Pros and cons of using native platform APIs

If you're building a meeting recorder or transcription app, you're probably inclined to start with the native APIs from Zoom, Microsoft Teams, and Google Meet.

That makes sense, but it might not be the best thing to do. Each platform's API has restrictions that are not immediately apparent, and limitations to its functionalities. Some APIs only offer post-meeting recordings. Others provide live audio and video but need additional permissions, account settings, or infrastructure.

Those differences matter when your product needs to work across platforms, customer accounts and use cases. Here's what each option gives you and how the alternatives compare.

Recording meetings with Zoom

Zoom has two native options to consider for meeting data: Cloud Recording APIs and Realtime Media Streams (RTMS).

For recordings and transcripts: Cloud Recording APIs let you retrieve files once the Zoom meeting is over. Cloud recording needs to be available and enabled, and you'll need to wait for the files to finish processing.

For live meeting data: RTMS gives your app access to audio, video, screen sharing, and transcripts during the meeting. You'll need the appropriate scopes and Zoom Developer Pack credits to use RTMS.

What to know before building: RTMS access depends on account and meeting settings. Admins control whether users can use RTMS and which apps can start automatically. Hosts can also require approval before an app receives meeting content. There's also a distribution step: If people outside your Zoom account will use the app, you'll need to complete Zoom's App Review process.

Note: RTMS only works with Zoom, so supporting platforms like Microsoft Teams or Google Meet means building separate integrations.

Recording meetings with Microsoft Teams

Microsoft Teams uses different approaches for retrieving recordings after a meeting and accessing media during the call.

For recordings and transcripts: Microsoft Graph lets your app retrieve meeting artifacts once they're processed. It can also notify your app when a recording or transcript is ready.

Depending on your access model, you may need permissions such as OnlineMeetingRecording.Read.All and OnlineMeetingTranscript.Read.All, along with the relevant administrator configuration. Microsoft documents the notification flow in its Graph integration guide.

For live audio and video: Microsoft's Real-time Media Platform gives application-hosted bots access to raw meeting media. That means building and running a Teams bot, handling concurrent calls, and keeping media sessions running throughout each meeting. It's a different architecture from downloading completed files through Graph.

What to know before building: Your customer's Microsoft 365 settings control what your app can access. Having the right Graph permissions doesn't override a tenant setting that disables transcript API access. Meeting recordings usually live in the organizer's OneDrive, while channel meeting recordings live in SharePoint. The organization's access and retention policies apply to those files.

Recording meetings with Google Meet

Google Meet also separates access to meeting artifacts from access to live media.

For recordings and transcripts: The Meet REST API exposes conference records, recordings, transcripts, transcript entries, and participant information. Recording files live in Google Drive, while structured transcript entries can be retrieved through the Meet API.

For live audio and video: Google provides a separate Meet Media API, but it's currently in Developer Preview. Your Cloud project, OAuth principal, and every meeting participant must be enrolled. That makes it impractical for a broadly available product, since you can't expect everyone in your users' meetings to be part of the preview.

What to know before building: Recording and transcription availability depends on the customer's Workspace edition, administrator settings, and meeting configuration. If a meeting never generates a recording or transcript, your app has nothing to retrieve.

Your app also needs the appropriate OAuth scopes. Depending on those scopes and how you distribute the app, additional verification may be required.

When recording meetings with native APIs make sense

Native APIs can be a good fit when the platform already provides the data your product needs.

For example, you might be building an internal tool that summarizes existing Teams transcripts. Or your product might simply need a list of participants from a Google Meet meeting.

In those cases, working directly with the platform can give you:

• Officially documented integration points.
• Access to the platform's recordings, transcripts, or meeting metadata.
• A workflow that fits the customer's existing meeting tools.
• Less need to build your own capture system when suitable recordings already exist.

However, your user base likely will need to record meetings on more than just on platform, even if they primarily record internal meetings. To be able to record meetings on other platforms, you'll need a separate native API integration for each provider. For example, a Teams integration won't give your app access to a customer's Zoom meeting or a partner's Google Meet call.

Where the extra work comes in

The challenge grows when your app needs to work across different meeting platforms and customer environments.

Each platform has its own authentication flow, permissions, data formats, and rules for accessing meetings. If you choose to use native APIs, you'll need to handle those differences in your code and help customers configure their accounts.

A few requirements deserve particular attention:

• Live access: Retrieving a transcript after a meeting is a different workflow from receiving audio during the call.
• Speaker information: Check whether you get participant names, speaker labels, mixed audio, or individual audio streams.
• External meetings: Test meetings organized outside the user's account or organization.
• Missing recordings: Decide what your app should do when recording wasn't enabled or an expected file never arrives.
• Customer setup: Make it clear which settings users can change themselves and which need an administrator.

Not accounting for these requirements will result in missing recordings, incorrectly attributed comments, or live features that only work after the meeting ends.

Building your own bot with browser automation

Another option is to build your own bot. Your bot opens the meeting link, joins as a participant, captures audio and video, and reads information such as captions or participant state from the page.

If you do decide to build your own bot, keep in mind that while a prototype can come together quickly, keeping it working takes more effort.

The browser interface will become an essential part of your integration. When Zoom, Google Meet, or Microsoft Teams change a button, introduce a different sign-in flow, or update a waiting room, the recording process of your bot is interrupted.

Your bot also needs to handle ordinary meeting events:

• Waiting for someone to admit it.
• Being denied entry or removed.
• Losing its connection.
• Recognizing when the meeting has ended.
• Recovering when the browser or capture process fails.

As usage grows, you'll also need infrastructure to run those browsers, monitor recordings, retry failed sessions, and roll out updates. Though building your own bot gives you control over the implementation, it also makes your team responsible for keeping the whole recording service running.

Comparing the approaches

Here's how native APIs, a self-built browser bot, and a desktop recording SDK compare.

For desktop recording, check the exact platform and browser combinations supported by the SDK. Support for a meeting platform doesn't necessarily mean every browser and operating system combination behaves the same way.

Using a desktop recording SDK

A desktop recording SDK lets you build recording into your app without creating the capture system from scratch.

A desktop recording SDK supports meeting capture across supported Windows and macOS environments. It provides live meeting data as well as recordings and transcripts after the call. Users can record through your desktop app without adding a recording bot to the meeting.

The value goes beyond accessing audio and video. A production recorder also needs to detect meetings, respond to mute changes, handle audio quality, and identify who is speaking, and a desktop recording SDK can handle all of this for you.

A desktop recording SDK will include:

• Automatic meeting detection: Your app can respond when a supported meeting starts.
• Mute-state detection: Microphone capture follows the user's meeting mute state.
• Echo cancellation: Helps prevent speaker audio from being captured again through the microphone.
• Audio synchronization: Keeps microphone and meeting audio aligned.
• Speaker names: Labels supported meeting transcripts with participant names.

Those are features your team would otherwise need to build, test, and maintain. With local desktop capture, you don't depend on each meeting platform's native recording API being enabled.

Choosing an approach

Start with the meeting experience you want to build.

Native meeting APIs can work well when you only need data from a specific platform and can operate within its permissions and access requirements. Building your own bot gives you more control, but also makes your team responsible for maintaining browser automation, capture infrastructure, and platform-specific behavior.

If you're building a cross-platform desktop recorder, a recording SDK reduces the work involved in supporting multiple meeting platforms and handling capture problems. Instead of maintaining separate integrations and rebuilding capabilities like meeting detection, mute handling, audio synchronization, and speaker identification, you can use one recording layer across the meeting platforms your customers already use.

If that matches what you're building, try an existing desktop recording SDK's sample app with the meeting platforms your users rely on. It gives you a concrete starting point for building your own recording workflow.
