FAQ

This is a general purpose FAQ. If you have more questions, please see the documentation for each product.

Authorization

How do I use an access_token with an account once it's been connected to the Nylas platform?

You can read more about how to use the access_token with the Nylas API here.

How can I re-authenticate an account?

On occasion, you will need to re-authenticate an account to bring it back into a synced state on the Nylas platform. To do this, please follow this guide.

Can we use the hosted Auth flow, but have it white-labeled as though it were embedded in our application?

Yes, you can white-label the authentication flow so that your end users do not see anything that is Nylas-specific while authenticating their accounts. This can be done in a limited way with our Hosted Oauth Flow, and without limitation via our Native Authentication Flow. To see the differences between the two, please reference this guide.

Billing

How is an account billed by Nylas?

Nylas will bill each email account that is actively syncing and set to a paid state within a billing period (i.e. per month). To learn more about how Nylas manages account billing, please see this guide.

Documentation

Do you have code samples for Authentication, Webhooks, or Syncing an account?

Yes, you can view code samples using our Node.js, Ruby, and Python SDK's here.

Spam Link

What is nyl.as?
