Integrate Yahoo Calendar and Contacts Into Your App in Minutes

The Nylas API syncs Yahoo emails to your platform and automatically creates contacts and calendar events from email messages.

Add Yahoo Contacts and Calendars in a Fraction of the Time

To integrate IMAP providers like Yahoo yourself would take around 3,280 hours. With Nylas, it takes just a few hours for one engineer.

One Integration, Every Provider

The Nylas API allows you expand your integration beyond Yahoo calendar, contacts, and email data. Nylas connects your to every email service provider and syncs data in real-time.

Hosted and Native Authentication

Freedom to choose between a secure login experience hosted by Nylas or one where users can log in directly in-app without ever needing to redirect to Nylas.

Leverage Email Data Extraction

Nylas uses email data extraction to create calendar events and contacts from Yahoo emails.

Slash the Costs of Your Yahoo Calendar and Contacts Integration

As your platform scales and your user base grows, so do costs for directly maintaining the Yahoo integration. Nylas handles these for you, including costs for:

  • Operating servers
  • Building Yahoo security features, infrastructure, and support
  • Troubleshooting bugs

The Nylas APIs abstracts away the ongoing maintenance tasks for you. Our API comes with out-of-the-box security certifications, and we power even more granular scopes than most providers to enhance security for your end-users.
