What this workflow does
This workflow has 14 nodes and runs when an HTTP POST request hits its webhook URL. Along the way it connects Airtable, Slack and Uploadtourl (community).

Trigger: When an HTTP POST request hits its webhook URL.
- Code: runs custom JavaScript code
- HTTP Fetch Photo Binary (HTTP Request): calls an HTTP API
- Upload To Url: uses Upload To Url

- Code: runs custom JavaScript code
- IG Create Carousel Container (HTTP Request): calls an HTTP API (POST)
- Wait: waits 8 seconds
