ChatGPT Codex + Zapier SDK turns one prompt into auto-published social posts

On October 6, @TawohAwa shared a five-step demo showing how to combine Codex mode in the ChatGPT desktop app with the newly released Zapier SDK, turning ChatGPT into a social media agent that posts automatically — a single-prompt workflow from topic selection to publishing.

Confirmed

Prerequisites: download the new ChatGPT desktop app, select Codex in the top-left corner, and sign up for a Zapier account first.
Step 1: Simply tell Codex in ChatGPT to "Install the Zapier SDK for me," and the agent can then operate 9000+ apps.
Step 2: Connect the apps the agent needs in Zapier. The author linked Google Sheets, a Facebook page, and Google Drive for posting and storing content.
Step 3: One prompt drives the whole workflow — example: "Give me 5 trending AI content topics, save them to Google Sheets, and write copy for one of them." Codex (the agent the author named Astra) then generates the content and stores it in Google Sheets.
Final step: The agent uses Zapier's connected actions to auto-publish the finished content to the Facebook page, then grabs the live post link and writes it back to Google Sheets.
Key feature: The Zapier SDK lets the agent connect directly to 9000+ apps without OAuth.

Why it matters

This workflow shows how a general-purpose agent, with ecosystem tools like the Zapier SDK, can reach real-world apps: it doesn't just generate content but also stores, publishes, and writes back results, forming a closed loop.
For content creators, it means topic ideation, writing, and publishing can be compressed into a single instruction, dramatically cutting social media operations costs.
