This template processes webhooks received from amoCRM in a URL-encoded format and transforms the data into a structured array that n8n can easily interpret. By default, n8n does not automatically parse URL-encoded webhook payloads into usable JSON. This template bridges that gap, enabling seamless data manipulation and integration with subsequent processing nodes.

Key Features:

  • Input Handling: Processes URL-encoded data received from amoCRM webhooks.
  • Data Transformation: Converts complex, nested keys into a structured JSON array.
  • Ease of Use: Simplifies access to specific fields for further workflow automation.

Setup Guide:

  • Webhook Trigger Node: Configure the Webhook Trigger node to receive data from amoCRM.
  • URL-Encoding Parsing: Use the provided nodes to transform the input URL-encoded data into a structured array.
  • Access Transformed Data: Use the resulting JSON structure for subsequent nodes in your workflow, such as filtering, updating records, or triggering external systems.

Example Data Transformation:

  • Sample Input (URL-Encoded): The following input format is typically received from amoCRM: $json.body['leads[update][0][custom_fields][0][id]']

  • Output (Structured JSON): After processing, the data is transformed into an easily accessible JSON array format: {{ $json.leads.update[‘0’].id }}

This output allows you to work with clean, structured JSON, simplifying field extraction and workflow continuation.

Code Explanation: This workflow parses URL-encoded key-value pairs using n8n nodes to restructure the data into a nested JSON object. By doing so, the template improves transparency, ensures data integrity, and makes further automation tasks straightforward.

Convert URL-Encoded Webhook Data to Structured Array

This n8n workflow listens for incoming webhook data that is URL-encoded, decodes it, and then transforms it into a structured array of objects, making it easier to process in subsequent workflow steps.

What it does

  1. Receives Webhook Data: The workflow starts by exposing a webhook URL. It listens for incoming HTTP POST requests.
  2. Decodes URL-Encoded Data: It takes the raw, URL-encoded string from the webhook body and decodes it into a plain text string.
  3. Extracts Key-Value Pairs: The decoded string is then parsed to extract individual key-value pairs, treating each pair as a separate item.
  4. Structures as Array: Each key-value pair is converted into a structured JSON object, and all these objects are collected into a single array, ready for further processing.

Prerequisites/Requirements

  • An n8n instance (cloud or self-hosted) to run this workflow.
  • A service that sends URL-encoded data to the webhook URL. (e.g., amoCRM or any other system sending application/x-www-form-urlencoded data).

Setup/Usage

  1. Import the Workflow:
    • In your n8n instance, go to "Workflows".
    • Click "New" or "Import from JSON".
    • Paste the provided JSON into the import dialog.
  2. Activate the Webhook:
    • The "Webhook" node will automatically generate a unique URL when the workflow is activated.
    • Copy this URL.
  3. Configure Sending Service:
    • In your external service (e.g., amoCRM), configure it to send data to the copied webhook URL using an application/x-www-form-urlencoded content type.
  4. Test the Workflow:
    • Send a test request from your external service to the webhook URL.
    • Execute the workflow manually or wait for a trigger to see the data being processed.
    • Inspect the output of the "Split Out" node to verify the structured array.

This workflow is particularly useful for integrating with systems that send webhook payloads in a URL-encoded format, allowing n8n to easily consume and process this data.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
