Who is this workflow for? This workflow demonstrates how to utilize the itemMatching(itemIndex: Number) function within the Code node of n8n. It enables the retrieval of linked items from earlier stages in the workflow, facilitating seamless data manipulation and integration across various platforms..

What does this workflow do?

  • Webhook Trigger:The workflow begins by activating a webhook that listens for incoming data or events, such as a new customer query or an order placement.

  • Retrieve Customer Data:The Customer Datastore integration fetches relevant customer information based on the incoming webhook data.

  • Code Node Execution:Within the Code node, the itemMatching(itemIndex: Number) function is employed to access specific linked items from previous nodes, allowing for precise data manipulation and retrieval.

  • Data Merge:The Merge node combines data from multiple sources, ensuring that all necessary information is consolidated for subsequent actions.

  • Send WhatsApp Message:Utilizing the WhatsApp integration, the workflow sends a tailored message to the customer, providing confirmation or additional information as required.

  • GitHub Integration:The workflow logs the interaction details to GitHub, maintaining a record of communications and actions taken.
