How do I connect an IMAP account with a non-email username?

Although Nylas's Hosted authentication does not accommodate non-email usernames for IMAP accounts, you have the option to utilize the Custom authentication endpoint to establish connections with these types of accounts.

If you wish to connect an IMAP account that uses a non-email username, follow these steps:

1. Begin by using the Custom authentication endpoint.
2. In the settings section of your API payload, make sure to include the following parameters:
   • imap_username: This should be set to the non-email username you intend to use (for example, "abc12343ab").
   • email: Input the complete email address associated with the mailbox here.
   • Additionally, include other standard IMAP connection parameters such as host, port, and password.

By following this method, you will be able to authenticate IMAP accounts where the login username is different from the actual email address.
