Linking Slash 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.
This source is currently in alpha. The interface and available tables may change.
The Slash connector syncs your corporate banking data – accounts, transactions, cards, invoices, invoice series, expense reports, and contacts – into PostHog.
Slash labels API access as beta. You may need to request access from Slash support at support@joinslash.com before connecting.
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 Slash.
- Get an API key from your Slash dashboard. Create a read-only key for your legal entity.
- Enter your API key in PostHog. If you're using a user-scoped key (rather than an organization key), also enter your Legal entity ID.
- 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 Slash data in PostHog.
