The Nylas Email API gives you a secure, reliable connection to your user’s inboxes that enables you to sync historic and live email data into your application in real-time and perform bi-directional email sync with full CRUD (create, read, update, delete) capabilities for Gmail, Microsoft Exchange, Outlook.com, Yahoo! Mail, AOL, IMAP, and the rest with just a few lines of code.
The Nylas Email API provides a REST interface that includes functionality to
- Read data from email messages and threads, such as email content, sender and recipient information, subject lines, dates, and more.
- Organize email inboxes with labels and folders.
- Update the unread and starred status of email messages.
- Manage and download file attachments.
- Create drafts and send emails.
- Search email inboxes for specific content.
This section covers all of the endpoints the Nylas Email API provides to enable you to integrate full email functionality into your app.
Messages are the fundamental object of the Nylas platform, and the core building block for most email applications. They contain several pieces of information, such as when a message was sent, the sender's address, to whom it was sent, and the message body. They can also contain file attachments, calendar event invitations, and more.
Threads are multiple messages that are grouped together into a single, first class object. Nylas threads messages together using a variety of heuristics; on Gmail and Microsoft Exchange accounts, messages are threaded together as close as possible to the representation in those environments. For all other providers (including generic IMAP), messages are threaded using a custom JWZ-inspired algorithm.
Folders are the primary component for organizing email inboxes from most providers and they behave like normal IMAP or filesystem folders. A message can only be contained within a single folder, but a thread with many messages might span multiple folders.
Gmail uses labels to organize email inboxes rather than folders, and messages may have more than one label. Nylas makes it easy to detect when accounts use this method of organization so you can ensure your end users have an experience that matches their provider of choice.
Files are any data attached to messages. Nylas allows you to download existing attachments from messages and threads and upload new files to be sent.
Drafts are special kind of message that has not been sent, and therefore its body contents and recipients are still mutable. The drafts endpoints let you read and modify existing drafts, create new drafts, send drafts, and delete drafts.
The Nylas Communications Platform provides other functionality that makes it easy for you to build your email integration.
Search functionality that is proxied to the account's provider for full-text search. Results are matched with objects that have been synced, and are then returned.
Filtering allow you to narrow requests based on specific parameters like subject line, senders and recipients, thread ids, and unread and starred status. Filters help you reduce the size of your API requests, resulting in faster performance.
Pagination makes it possible to control the number of results that are returned.
Webhooks allow your application to receive notifications when certain events occur such as emails being received or sent, or other changes to an email inbox.
Deltas enable you to process new data quickly without fetching an index of the user's email inbox or performing a large number of API calls.
Views allow you to customize the response for any endpoint to return only specific information that you want.
