"content": "## Trigger - Two Options\nTo use this workflow, you have two trigger options.\n\nThe default trigger is **\"When clicking 'Test workflow'\"**, allowing you to manually test the scenario.\n\nIf you want to use this workflow in production, you can choose one of the following triggers. You'll need to **select the one you prefer and enable it**.:\n\n### Schedule Trigger \nThis trigger checks at regular intervals (e.g., every 5 minutes) if a new post has been published on your WordPress blog and triggers the workflow accordingly. \n\n\u2705 **Easy to set up** \n\u2705 **Automates AI summaries without manual intervention** \n\n\u26a0\ufe0f If you run the workflow manually once, the AI-generated summaries will be added to Google Sheets and processed in later steps to prevent duplication. \n\n\ud83d\udca1 **Recommended follow-up nodes:** If you choose this trigger, the following nodes are suggested in the template: \n- **`Date & Time - Subtract`**: Subtracts the scheduled interval from the current execution timestamp. For example, if the workflow runs every 5 minutes, it subtracts 5 minutes from the execution time. \n- **`WordPress - Get Posts`**: Uses the output of the `Date & Time - Subtract` node as a filter to retrieve only posts published after the last execution. \n\n### Webhook Trigger \nIf you're familiar with webhooks, you can set up a webhook that triggers when a new post is published. \n\n\u2705 **Faster than scheduled triggers** \n\u2705 **More event-driven** \n\nYou can implement this using either: \n- A **Webhook plugin** on WordPress (not recommended due to plugin dependency). \n- A **PHP function** that triggers the webhook with authentication for security. \n\n\u26a0\ufe0f **Be cautious** with how the webhook is triggered\u2014you may not want it to fire on every post edit. \n\n\ud83d\udca1 **Recommended follow-up nodes for this option:** \n- **`Set Fields - From Webhook Input`**: Configures the fields based on the data sent to the webhook. \n- **`WordPress - Get Post`**: Retrieves the post using the `post_id` received from the webhook, ensuring higher accuracy than the schedule trigger approach. \n"

This makes it easier to fix any issues. \n- You can **add filters** (category, tag, date, etc.) to target only the posts for which you want an AI Summary. \n- You can enable the **\"Get All Posts\"** option in the node if you want summaries for all posts\u2014**but make sure this is intentional**. \n- The **more posts** you process, the **higher the cost** in OpenAI API usage. \n"

Depending on your **publication frequency** and the **schedule interval** you've chosen, multiple posts could be retrieved in a single execution. This ensures each post is processed sequentially. \n\n### \ud83d\udd39 In Production - Using the \"Webhook Trigger\" \nWith a **Webhook Trigger**, the workflow typically runs for **one post at a time**, meaning the **\"Loop Over Items\"** node is not strictly necessary. \n\n- **You can remove it** for a slightly more efficient workflow. \n- **However, keeping it won\u2019t cause any issues**\u2014it will simply loop over one item instead of multiple. \n"

The workflow **skips processing** and moves to the `\"Loop Over Items\"` node. \n- \u274c **If no row exists for the `post_id`** \u2192 The post **does not have an AI Summary**, so the workflow continues along the execution path that leads to AI Summary generation. \n"

More details about this step are provided in the next sticky note. \n\n### \ud83d\udd39 WordPress - Get Post \n- The **`context=edit`** option is enabled to retrieve the **raw** post data. \n- This is necessary because the post content will be **updated later in the workflow**. \n\n### \ud83d\udd39 HTML to Markdown \n- Converts the retrieved HTML content into **Markdown** format. \n- This makes the text **easier to process** for the LLM (Large Language Model) in the next step. \n- Markdown ensures that the AI better understands the structure and formatting of the content. \n"

}How to Use an n8n Template
1
Create a New Workflow
Click "New Workflow" in your n8n dashboard to get started.
2
Copy & Paste Template
First, copy this template:
Click here to copy the JSON
.
Then, in n8n, click the three dots (···) → "Import from file" and paste the JSON code.
3
Customize the Nodes
Go through each node in the workflow to update inputs like spreadsheet IDs, email addresses, or message content. Adjust field mappings to match your data.
4
Grant Access
For nodes that connect to external apps (like Google Sheets or Slack), you'll need to grant access. Connect your accounts using OAuth or an API key and save the credentials in the node.
5
Test It
Run the workflow by clicking "Execute Node" for each step or "Run Once" for the whole thing. Check the right sidebar to inspect data and debug any errors (they'll show up in red).
6
Activate Workflow
Once everything works as expected, click the "Activate" toggle to turn your workflow on. You're all set!
