# Blog and page triggers, step by step

Shopify sends no notification at all when a blog, a blog post or a page changes. These three triggers find changes by checking on a schedule, so expect a short delay rather than an instant event.

**On this page:** [Blog Post Update](#blog-post-update), [Page Update](#page-update), [Blog Update](#blog-update)

> [!TIP]
> **New to Shopify Flow?**
> Every example follows the same five moves: pick the trigger, add a condition, add an action, turn the workflow on, check Event History. [Your first workflow, step by step](https://docs.workflow-trigger-extensions.app/first-workflow-tutorial.md) shows each of them with screenshots.

*Where you find them: in Shopify Flow choose Select a trigger, open Workflow Trigger Extensions and search for "Blog".*

## Blog Post Update

Fires when a blog post is changed: title, body, summary, tags, author, or whether it is published.

| | |
| --- | --- |
| **Fires from** | Checked on a schedule, because Shopify sends no webhook for it |
| **Permission** | **Blog, Blog Post & Page Data Access** |
| **Switched on** | Turning on a Flow workflow that uses it switches it on. Its own switch is on the app's **Triggers** page |

**Use it for**

- Announce newly published posts in a team channel or to a newsletter tool.
- Send edited posts to translation.

### What Blog Post Update sends to your workflow

| Variable in Flow | Type | What it holds |
| --- | --- | --- |
| `article` | Object | The blog post (article) that was updated |
| `article.id` | ID |  |
| `article.title` | Text |  |

| `eventId` | Text | The id of this event. Search for it in the app's Event History to see exactly what was sent. |

### Example: Announce a published post

1. Pick **Blog Post Update** as the trigger.
2. Add a **Condition**: `article.isPublished` **Equal to** `true`.
3. Add **Send HTTP request** to Slack: `{{article.title}} by {{article.author.name}} was updated`.
4. Turn the workflow on.

> [!NOTE]
> **Good to know**
> The event carries the post as it is now, without old values. To act only on the first publication, write a tag or metafield in the workflow and check for it in the condition.

## Page Update

Fires when an online store page is changed: title, content, template, or whether it is published.

**Use it for**

- Have legal re-check policy-like pages after an edit.
- Tell support that the FAQ or the shipping page changed.
