Hey :waving_hand: @kevin.sile !

You can only edit the Path in the Webhook UI.

You need to edit your .env file or docker compose file and add :

WEBHOOK_URL=https://n8n.example.com

Have fun n8n-ing :slight_smile: !

Hi Kevin.sile

I’ve worked on several advanced automation workflows using n8n, and I’ve seen this kind of issue before. If you’re looking to edit or modify the data coming from your Webhook before execution, here’s the best approach :backhand_index_pointing_down:

:wrench: Recommended Workflow Setup

  1. Open the Webhook Node

    • Copy the Webhook URL if you need to use or customize it externally (it cannot be edited directly inside n8n).

  2. Process Data Before Execution
    Add one of the following nodes right after the Webhook node:

    • Set Node – for simple replacements or adding values

    • Function/Code Node – for more advanced manipulation
      Example (Function Node):

    return [
  {
    json: {
      ...items[0].json,       // Keep original data
      updatedField: "New value",
      originalField: undefined // Replace or remove data
    }
  }
];

  3. Optional – Dynamic Routing
    If you’re working in multiple environments (test vs live), you can:

    • Use an IF / Switch node

    • Or manage different Webhook URLs with variables

      Expert Tip

      If your goal is to transform or validate the webhook data before triggering downstream logic (API calls, CRM updates, etc.), it’s more reliable to use the Webhook only for reception and handle all changes in subsequent nodes. This gives you full flexibility.

      If you need help setting this up or customizing the function logic, feel free to tag me here—I’d be happy to support you further or even review the workflow structure if needed.

      Good luck with the build.
