The Nylas Sync Engine provides a RESTful API on top of a powerful email sync platform, making it easy to build apps on top of email. See the full API documentation for more details.

Installation and Setup
git clone https://github.com/nylas/sync-engine.git
Feel free to check out the
Vagrantfilewhile this starts up. It creates a host-only network for the VM at
And voilà! Auth an account via the commandline to start syncing:
bin/inbox-auth [email protected]
inbox-auth command will walk you through the process of obtaining an authorization token from Google or another service for syncing your mail. In the open-source version of the sync engine, your credentials are stored to the local MySQL database for simplicity. The open-source Nylas Sync Engine does not support Exchange, but the hosted version does.
The sync engine will automatically begin syncing your account with the underlying provider. The
inbox-sync command allows you to manually stop or restart the sync by running
inbox-sync stop [YOUR_ACCOUNT]@example.com or
inbox-sync start [YOUR_ACCOUNT]@example.com. Note that an initial sync can take quite a while depending on how much mail you have.
Nylas API Service
The Nylas API service provides a REST API for interacting with your data. To start it in your development environment, run command below from the
/vagrant folder within your VM:
This will start the API Server on port 5555. At this point You're now ready to make requests! If you're using VirtualBox or VMWare fusion with Vagrant, port 5555 has already been forwarded to your host machine, so you can hit the API from your regular web browser.
You can get a list of all connected accounts by requesting
http://localhost:5555/accounts. This endpoint requires no authentication.
For subsequent requests to retreive mail, contacts, and calendar data, your app should pass the
account_id value from the previous step as the "username" parameter in HTTP Basic auth. For example:
curl --user 'ACCOUNT_ID_VALUE_HERE:' http://localhost:5555/threads
If you are using a web browser and would like to clear your cached HTTP Basic Auth values, simply visit http://localhost:5555/logout and click "Cancel".
Now you can start writing your own application on top of the Nylas API! For more information about the internals of the Nylas Sync Engine, see the Nylas API Documentation.
We provide a fully managed and supported version of the Nylas sync engine for production apps. Read more at https://nylas.com

We require all authors sign our Contributor License Agreement when submitting pull requests. (It's similar to other projects, like NodeJS or Meteor.)
For the sake of simplicity and setup speed, the development VM does not include any authentication or permission. For developing with sensitive data, we encourage developers to add their own protection, such as only running Nylas on a local machine or behind a controlled firewall. Note that passwords and OAuth tokens are stored unencrypted in the local MySQL data store on disk. This is intentional, for the same reason as above.
