Linking Blogger as a source
This source is currently in alpha. The interface and available tables may change.
The Blogger connector syncs your publicly visible Blogger content – posts, pages, and comments – into the PostHog Data warehouse, so you can analyze your published content alongside your product data.
Prerequisites
You need a Google account with a project in the Google Cloud console where you can create an API key and enable the Blogger API v3. The API key reads publicly visible content only. Drafts and admin-only data require OAuth, which isn't supported yet.
Adding a data source
- In PostHog, go to the Sources tab of the data pipeline section.
- Click + New source and click Link next to this source.
- Enter your credentials (see Configuration below) and click Next.
- Select the tables you want to sync, choose a sync method and frequency, then click Import.
Once the syncs are complete, you can start querying this data in PostHog.
When linking Blogger, you'll need:
- API key – create one in the Google Cloud console and enable the Blogger API v3 for the project.
- Blog ID – shown in the Blogger dashboard URL (
blogger.com/blog/posts/<blogId>).
Sync modes
Each table can be synced in one of several modes, depending on what the source supports:
- Webhook (when available) – the source pushes changes to PostHog in real time. Fastest freshness, lowest ongoing cost, and the only mode that reliably captures updates and deletes.
- Incremental – only new or updated rows are synced on each run, using a cursor field (such as an
updated_attimestamp). Cheaper than a full refresh, but deletes aren't captured. - Append only – new rows are appended using a cursor field; existing rows are never updated. Ideal for immutable, append-only tables like event logs.
- Full refresh – the whole table is reloaded on every sync. Use it when a table has no reliable cursor or when you need deletions reflected.
See sync methods for a full explanation of how each mode works and how to choose between them.
Configuration
| Option | Type | Required |
|---|---|---|
API key | password | Yes |
Blog ID | text | Yes |
Supported tables
| Table | Description | Sync method | Incremental field | Primary key |
|---|---|---|---|---|
blogs | The Blogger blog being synced, with its metadata and aggregate post/page counts. | Full refresh | — | id |
posts | Posts published to the blog. Synced incrementally on the immutable | Incremental, Full refresh | published | id |
pages | Static pages on the blog. Full refresh only — the API exposes no date filter for pages. | Full refresh | — | id |
comments | Comments across all of the blog's posts. Synced incrementally on the immutable | Incremental, Full refresh | published | id |
Troubleshooting
- If you see an authentication error, your API key is invalid or has been revoked. Create a new key in the Google Cloud console with the Blogger API enabled, then reconnect.
- If you see a permissions error, the key cannot access this blog. Enable the Blogger API for your Google Cloud project and confirm the blog is publicly visible, then reconnect.
If your sync is failing or data looks wrong, see the Data warehouse troubleshooting guide. If that doesn't help, contact support – we're happy to help.
