How it runs
Trigger: On a schedule (every day).
- Get Pending (Google Sheets): uses Google Sheets
- If: checks a condition and branches into true / false
- Generate Description for Instagram (OpenAI): uses OpenAI
- Basic LLM Chain: sends a prompt to an LLM, with model: OpenAI Chat Model; output parser: Item List Output Parser
- Loop Over Items (Loop Over Items (Split in Batches)): loops over the items in batches
- IG images ID (HTTP Request): calls an HTTP API
- OpenAI - Generate Image (HTTP Request): calls an HTTP API
- Images ID Array (Code): runs custom JavaScript code
- Separate Image Outputs (Split Out): splits a list into separate items
- IG Media Carousel (HTTP Request): calls an HTTP API
…plus 11 more steps. See the full node list below.
