This template starts when a webhook posts a topic, asks ChatGPT for platform captions, generates a still image, emails you the drafts, then publishes to your Facebook Page, Instagram, and X.
Connect Gmail, Facebook Pages, Instagram for Business, and X. ChatGPT and image generation are Latenode AI steps. Paste the webhook URL into the form or app that sends the topic.
Latenode bills workflow runtime in CPU seconds. The first 10,000 CPU seconds are free each month, then usage follows pay-as-you-go CPU-second pricing. Plug-and-Play (PnP) AI nodes are billed separately—each PnP token is $1 USD, charged pay-as-you-go at vendor cost plus a small processing fee, with no API keys required.

The scenario starts when a webhook POSTs a topic for ChatGPT to write from.
ChatGPT returns captions for Facebook, Instagram, and X. Image generation creates a still to go with the posts. This step does not render video.
Gmail sends you the captions and image so you have a copy of what will publish.
Facebook Pages, Instagram, and X publish the caption and still to the accounts you connect.
Add a webhook trigger and copy the URL. Have your form or app POST a topic in JSON to that URL.
Add those four connections. Pick the Gmail inbox for drafts, the Facebook Page, the Instagram professional account, and the X account that should publish.
Ask ChatGPT for captions from the topic. Generate the still with image generation. You do not paste an OpenAI API key for those Latenode AI steps.
Send the drafts with Gmail. Create a photo post on the Facebook Page, create a photo post on Instagram, and upload media then create the post on X. Send a test topic and confirm the email plus the three posts.

This template keeps a light Instagram engagement loop. A schedule asks ChatGPT for hashtags. PhantomBuster fetches recent posts for those tags. JavaScript skips URLs already stored in SharePoint, then PhantomBuster likes one remaining post. SharePoint saves that URL so the next run does not repeat it. Connect SharePoint and PhantomBuster. Put the PhantomBuster API key on the PhantomBuster connection.
This template starts when you add a prospect URL to Google Sheets. Apify scrapes public contact details. JavaScript cleans name, company, and phone. ChatGPT writes a short outreach script. WhatsApp Business Cloud sends an approved template to that number, then Google Sheets logs the send. Connect Google Sheets, Apify, and WhatsApp Business Cloud. Put the Apify API key on the Apify connection. ChatGPT is a Latenode AI step.
This template receives TikTok Lead Generation form submits on a Latenode webhook, maps name, email, phone, and custom answers in JavaScript, and appends a row in Google Sheets. If the webhook only includes a lead id, the same JavaScript node loads the full lead from the TikTok Marketing API with your token stored in that node. Connect Google Sheets, then point the TikTok form webhook at the Latenode URL. Add a new worksheet when you want each campaign on its own tab.
