Linking Amplitude as a source

The Amplitude connector syncs your raw events, cohorts, and annotations into PostHog. It authenticates against Amplitude's Export API, Cohorts API, and Annotations API using your project's API key and secret key.

Adding a data source

1. Go to the sources tab of the data pipeline section in PostHog.
2. Click + New source and then click Link next to Amplitude.
3. You need an API key and secret key from Amplitude. In Amplitude, go to Settings → Organization settings → Projects and open the project you want to sync. Copy the project's API key and secret key. Then choose your Region — US (amplitude.com) or EU (analytics.eu.amplitude.com) — to match where your Amplitude project is hosted.
4. Back in PostHog, enter the API key, Secret key, and Region, then click Next.
5. Select the tables you want to sync, set the sync method and frequency, then click Import.

Once the syncs are complete, you can start using Amplitude data in PostHog.

Available tables

Incremental tables sync only new or updated records on each run. Full refresh tables reload all data on each sync.

Sync limitations

The events stream uses Amplitude's Export API, which enforces a roughly 2-hour data latency — events uploaded to Amplitude within the last couple of hours may not yet be available to sync. The initial sync only pulls the last 30 days of events; subsequent incremental syncs fetch newer data using server upload time as the cursor.
