Linking Svix as a source

Let AI connect your sources for you

Skip the manual setup — run this in your project and the wizard auto-detects your databases and APIs and connects them to PostHog.

The Svix connector syncs your webhook infrastructure data — applications and event types — into PostHog.

Adding a data source

Go to the sources tab of the data pipeline section in PostHog.
Click + New source and then click Link next to Svix.
You need an API key from Svix. In your Svix dashboard, go to Settings > API Access and create or copy an API key (starts with sk_...).
Back in PostHog, enter your API key and click Next.
Select the tables you want to sync, set the sync frequency, then click Import.

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