How do I integrate Microsoft Outlook API with my application?

Apideck provides a unified CRM API that makes Microsoft Outlook integration simple. Sign up for free, enable Microsoft Outlook in your dashboard, and use our Vault component to let your users connect their Microsoft Outlook accounts. We handle OAuth authentication, token refresh, and data normalization automatically.

What Microsoft Outlook data can I access through Apideck?

Our Microsoft Outlook integration supports 2+ data models including users, and contacts. You can perform read and write operations through our unified API, working with the same code structure across all crm platforms.

How does Microsoft Outlook authentication work with Apideck?

Apideck's Vault handles Microsoft Outlook authentication completely. Your users connect their Microsoft Outlook accounts through our secure, white-label UI. We manage OAuth tokens, automatic refresh, and credential storage, so you never have to implement Microsoft Outlook's auth flow yourself.

How do I keep my app in sync with Microsoft Outlook?

While Microsoft Outlook has limited native webhook support, Apideck provides polling-based sync and virtual webhooks to keep your data current. Configure your sync frequency in the dashboard, and we'll handle fetching updates from Microsoft Outlook.

Why use Apideck instead of Microsoft Outlook's direct API?

Using Apideck's unified API instead of Microsoft Outlook's direct API saves significant development time. You get normalized data models, automatic auth handling, and the same integration code works with 200+ other apps. When Microsoft Outlook updates their API, we handle the changes so your integration keeps working.
