Listen on New Emails on an IMAP Mailbox

This n8n workflow listens for new emails on an IMAP mailbox, processes their content, and prepares it for further use, potentially for an API call or data transformation. It's designed to automate the initial steps of handling incoming email data.

What it does

This workflow performs the following steps:

1. Listens for New Emails: It acts as a trigger, constantly monitoring a specified IMAP mailbox for new incoming emails.
2. Processes Email Content: It takes the raw email data and converts any binary attachments into a usable format.
3. Parses XML Content (if present): If the email body or an attachment contains XML data, it parses this content into a structured JSON object.
4. Edits Fields: It allows for the modification or creation of fields within the processed email data, preparing it for subsequent actions.
5. Performs an HTTP Request: It can then use the processed and transformed email data to make an HTTP request to an external API or service.

Prerequisites/Requirements

To use this workflow, you will need:

• IMAP Mailbox Access: Credentials for an IMAP email account that n8n can connect to.
• n8n Instance: A running instance of n8n to import and execute the workflow.
• Target API/Service: If you intend to use the HTTP Request node, you'll need the endpoint and any necessary authentication for the service you wish to interact with.

Setup/Usage

1. Import the Workflow: Download the provided JSON and import it into your n8n instance.
2. Configure IMAP Credentials:
   • Click on the "Email Trigger (IMAP)" node.
   • Under "Credentials", select an existing IMAP credential or create a new one. You will need your IMAP server address, port, username, and password.
3. Configure "Convert to/from binary data" Node: This node is set up to handle binary data from the email. Review its settings to ensure it correctly processes any attachments or specific parts of the email you are interested in.
4. Configure "XML" Node: If your emails contain XML data that needs parsing, ensure this node is correctly configured to target the appropriate field containing the XML.
5. Configure "Edit Fields (Set)" Node: Customize this node to add, remove, or modify any fields from the email data as needed for your subsequent steps.
6. Configure "HTTP Request" Node:
   • Specify the HTTP Method (e.g., POST, GET).
   • Enter the URL of the API endpoint you want to send the data to.
   • Configure any necessary Headers (e.g., Content-Type, Authorization).
   • Map the data from the previous nodes to the Body of your request as required by your API.
7. Activate the Workflow: Once configured, activate the workflow to start listening for new emails.
