How do I integrate Gmail API with my application?

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

How does Gmail authentication work with Apideck?

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

How do I keep my app in sync with Gmail?

While Gmail 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 Gmail.

Why use Apideck instead of Gmail's direct API?

Using Apideck's unified API instead of Gmail'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 Gmail updates their API, we handle the changes so your integration keeps working.

How quickly can I build a Gmail integration?

Most developers ship a working Gmail integration within a day using Apideck. Sign up for a free trial (no credit card required), enable Gmail, and make your first API call within minutes. Our SDKs for Node.js, Python, and other languages make implementation straightforward.
