It works end to end, but you may still hit rough edges.

Unstructured is a document ETL platform that turns raw files (PDFs, Office documents, emails, and more) into RAG-ready structured data. ## Prerequisites - An [Unstructured platform](https://platform.unstructuredapp.io) account (a free tier is available). - An Unstructured API key. The key has account-wide read access, so no extra scopes are required. ## Adding a data source 1. In PostHog, go to the [Sources tab](https://app.posthog.com/data-management/sources) of the data pipeline section. 2. Click **\+ New source** and click **Link** next to this source. 3. Enter your credentials (see [Configuration](#configuration) below) and click **Next**. 4. 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 Unstructured, you'll need: - **API key** – sign in to the [Unstructured platform dashboard](https://platform.unstructuredapp.io), open **API Keys**, and generate a new key. Copy the key and paste it into the **API key** field in PostHog. Leave **API host** blank unless Unstructured provisioned your account with a custom API URL, in which case enter that origin (for example `https://platform.unstructuredapp.io`). ## 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_at` timestamp). 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](https://posthog.com/docs/data-pipelines/sources.md#sync-methods) for a full explanation of how each mode works and how to choose between them. The `notifications` table supports incremental sync on `created_at`. Every other table syncs as a full refresh: workflows and connectors are mutable configuration objects, and jobs have no server-side time filter. These are low-volume inventory tables, so a full refresh each sync always reflects the current state. The `job_details` and `job_failed_files` tables make one request for each job on every sync. `job_failed_files` skips jobs that report no failed files. `job_details` is off by default, so turn it on only when you need per-node processing counts. ## Configuration | Option | Type | Required | | --- | --- | --- | | `API key` | password | Yes | | `API host` | text | No | ## Supported tables | Table | Description | Sync method | Incremental field | Primary key | | --- | --- | --- | --- | --- | | `workflows` | Workflows that define how Unstructured ingests, processes, and routes documents from sources to destinations. | Full refresh | — | — | | `jobs` | Individual runs of a workflow at a point in time, including status and runtime. | Full refresh | — | — | | `sources` | Source connectors that ingest files or data into Unstructured from an external location. | Full refresh | — | — | | `destinations` | Destination connectors that send Unstructured's processed data to an external location. | Full refresh | — | — | | `job_details` | Processing details of each job: per-node document counts, overall outcome, and progress. | Full refresh | — | — | | `job_failed_files` | Files that failed to process in a job, with the workflow node that failed each one and the error. | Full refresh | — | — | | `notifications` | Platform notification events, such as a job that started, completed, or failed. | Incremental, Full refresh | created\_at | — | ## Troubleshooting - **Invalid API key** – regenerate the key in the Unstructured platform dashboard and reconnect. The key is account-wide, so a valid key can read every table. - **Custom API host** – if your account uses a custom API URL, make sure the **API host** field matches the origin Unstructured gave you. The scheme is forced to HTTPS. If your sync is failing or data looks wrong, see the [Data warehouse troubleshooting guide](https://posthog.com/docs/data-warehouse/troubleshooting.md).
