What this workflow does

This workflow has 7 nodes and runs when an HTTP POST request hits its webhook URL. It uses only n8n's built-in nodes.

How it runs

Trigger: When an HTTP POST request hits its webhook URL.

1. Check if all params are provided (If): checks a condition and branches into true / false
2. Retrieve All Slide Elements (HTTP Request): calls an HTTP API
3. Error Missing Fields (Respond to Webhook): sends the response back to the webhook caller
4. Retrieve matching Images ObjectIds (Code): runs custom JavaScript code
5. Replace Images (HTTP Request): calls an HTTP API (POST)
6. Respond to Webhook: sends the response back to the webhook caller

Before you upgrade to n8n 3.0
