Integrate the Microsoft Teams API.Caddi writes and runs the integration for you.
Microsoft Teams has a REST API through Microsoft Graph. Self-serve for developers with a Microsoft 365 tenant that includes Teams, via Entra app registration; application permissions need admin consent.

The connection is a project before it does anything.
Before the first record moves: an app registration, credentials, token refresh, and somewhere to host and monitor the code. Per-endpoint throttling across per-app, per-app-per-tenant, per-resource and per-user dimensions (e.g., GET /teams/{id} is 1,500 rps per app, 30 rps per app per tenant, 4 rps per team).
Register an app, store Microsoft Teams credentials, refresh tokens and code around the rate limits.
Connect your Microsoft Teams account once. Caddi holds the connection.
The job doesn't stop at Microsoft Teams.
An intake, a filing or a client update also runs through email, documents and the other systems your team works in. The Microsoft Teams API only reaches Microsoft Teams.
Each extra system is another API, another set of credentials, another integration to own.
One automation runs across every tool the job touches, each through its API.
Someone has to own the code.
API versions change, fields get added and your process moves. Posting chat/channel messages with application (app-only) permissions is supported only for migration.
A developer patches and redeploys the integration each time.
The person who does the work updates it by showing or describing the change. Every automation is reviewed before it runs in production, and every run is logged.

When to build the Microsoft Teams integration in-house
When you have engineers and the integration is your product, or you need one narrow sync between two systems and someone to own it. When the goal is getting Microsoft Teams work off someone's desk, the build is the slow part, and Caddi does it for you.
What teams usually want the Microsoft Teams API for
Approval flow
Caddi posts an approval request in the right Teams channel, captures the response, and writes the decision back to the source system.
Meeting follow-up
When a Teams meeting ends, Caddi writes notes to the CRM and posts the action items back to the channel.
Critical-event notify
When a high-priority event lands in email or the CRM, Caddi posts to the relevant Teams channel with full context.

Microsoft Teams API questions
Does Microsoft Teams have an API?
Yes. Microsoft Teams has a REST API through Microsoft Graph, authenticated with OAuth 2.0 via Microsoft Entra ID (delegated or application permissions). The official documentation is at https://learn.microsoft.com/en-us/graph/teams-concept-overview.
How do I get access to the Microsoft Teams API?
Self-serve for developers with a Microsoft 365 tenant that includes Teams, via Entra app registration; application permissions need admin consent.
Does the Microsoft Teams API have rate limits?
Per-endpoint throttling across per-app, per-app-per-tenant, per-resource and per-user dimensions (e.g., GET /teams/{id} is 1,500 rps per app, 30 rps per app per tenant, 4 rps per team).
Can I connect Microsoft Teams to my other tools without writing code against its API?
Yes. With Caddi you show the Microsoft Teams task once, the way you'd train a new hire, and Caddi builds it as verified code that runs across Microsoft Teams and the other tools the job touches. Steps that need a person's judgment are handed to Copilot or Claude, and Caddi monitors those too.
Do I need a developer to automate Microsoft Teams with Caddi?
No. There is no integration code for you to write or maintain. Every automation Caddi builds for Microsoft Teams is reviewed before it runs in production, and every run is logged.
