| `credential_id` | Pin one specific login (UUID), and therefore one specific Microsoft 365 display identity, for this bot. |
| `fallback` | What to do when no login slot is available: `fail` (default) fails bot creation with `TEAMS_LOGIN_UNAVAILABLE`; `anonymous` silently falls back to an anonymous join. |

Leave `teams_config` `null` for anonymous Teams joins, Zoom, or Google Meet.

## Key concepts

### Visible name and profile

Microsoft controls a signed-in participant's identity. Once `teams_config` resolves a login, Teams uses that Microsoft 365 account's display name and profile picture and ignores `bot_name`.

For multiple brands or customer-specific notetaker names:

1. Create one Microsoft 365 account per desired visible identity and set its display name and profile picture in Microsoft 365.
2. [Register each account as a teams login](/docs/api-v2/reference/teams-logins/createTeamsLogin). The login's `name` field is only an internal Meeting BaaS label.
3. Pass that login's `credential_id` when you [create the bot](/docs/api-v2/reference/bots/createBot).

Use `email_group` only when any account in that pool is acceptable. If every account in a pool has the same public display name, pooling preserves the brand while distributing load.

### Getting past the lobby

Signing in is what gets the bot admitted. When the account belongs to the **organizer's organization** (or the meeting's lobby policy admits people in the org), the authenticated bot is let in automatically instead of waiting in the lobby as an anonymous guest. For meetings restricted to signed-in users, an authenticated bot is the only way in — an anonymous bot fails with `TEAMS_LOGIN_REQUIRED`.

Each login supports up to **20 concurrent sessions**. When you dispatch bots with an `email_group`, the assigner picks the least-loaded active login and skips any login at capacity. If every login in a pool is saturated, bot creation fails with `TEAMS_LOGIN_UNAVAILABLE` (or falls back to anonymous, per your `fallback` setting). Create more logins to raise the ceiling, and configure a [utilization alert](/docs/api-v2/alerts) to stay ahead of saturation (the [utilization endpoint](/docs/api-v2/authenticated-bots/teams/sending-authenticated-bots#monitoring-pool-utilization) gives an on-demand view).

Microsoft Teams can merge participants that use the same Microsoft 365 account into one attendee when they join the same meeting. Use a distinct account for each bot that must appear separately in one call.

## Round-robin pool (recommended)

Assign the bot to the least-loaded active login in a pool by passing `email_group`. This spreads load across all logins sharing that group and is the right default for unattended recording at scale.

## Control the visible identity per bot

Use one Microsoft 365 account per desired display identity, [register each account as a teams login](/docs/api-v2/reference/teams-logins/createTeamsLogin), then pin the intended login with `credential_id`:

The `name` stored on a teams login is an internal Meeting BaaS label. It does not change what participants see. Change the account's display name and profile picture in Microsoft 365.

Use separate `email_group` values for separate brands, and place only interchangeable identities in each pool. Pool selection is load-based, so a pool containing different public identities cannot guarantee which one appears in a given meeting.

Microsoft Teams can merge multiple participants using the same Microsoft 365 account into one attendee in the same meeting. Give simultaneous bots distinct accounts when each must appear separately.

## Fallback behavior
