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"
