Linking Resend as a source

The Resend connector pulls your Resend data – audiences, broadcasts, contacts, domains, and emails – into the PostHog data warehouse.

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 Resend.
Next, you need an API key from Resend. In your Resend API keys settings, create an API key. Grant the key full access (or a read-enabled access token) so that audiences, broadcasts, contacts, domains, and emails can be read. Copy the key value (it starts with re_).
Back in PostHog, enter the key in the API key field and click Next.
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 Resend data in PostHog.
