Authentication

IMAP uses API keys for authentication. When you connect your IMAP account, Pipedream securely stores the keys so you can easily authenticate to IMAP APIs in both code and no-code steps.

Below are the required fields to connect your IMAP account to Pipedream:

  • host: Enter the host Pipedream should connect to. Refer to your email provider's IMAP instructions if you aren't sure what to enter.
  • email: Enter the email address you use to sign in to the account you'd like to connect.
  • password: This is the password you use to sign in to your email account. Note: in order to connect a Gmail account, you must use an App Password.
  • port: Specify the port number, either 143 (default) or 993. Refer to your email provider's IMAP instructions if you aren't sure which to use.

For Gmail accounts, refer to these instructions.
