n8n

n8n is the self-hosted counterpart to Zapier in Saturation’s automation catalog: the same Saturation API surface, reached from a workflow tool your team runs on its own infrastructure. Where Zapier fans out to a hosted directory, n8n points at an npm package you install into your own instance.

How it works

Saturation ships a community node package, n8n-nodes-saturation, that you install into your n8n instance from the community nodes dialog. It provides a Saturation node and a Saturation Trigger, generated against the same API contract as the Zapier app, so the trigger and action vocabulary mirrors it.

Popular recipes

• Cost log to your warehouse: the Saturation Trigger fires on New Transaction and the workflow appends every posted cost to Postgres, BigQuery, or a sheet.
• PO approval routing: the trigger fires on Purchase Order Status Changed and notifies the approver in Slack, Teams, or email as status moves.
• Receipt intake: the Saturation node’s Drop Document (And Assign) operation pulls receipts off an inbox or drive and attaches them to the cost.
• Nightly budget snapshot: Get Budget Summary runs on a schedule and writes topsheet totals somewhere your finance team already looks.

Who it is for

Teams that want automation without a hosted middleman: everything runs on infrastructure you control, against the same events and operations the hosted Zapier integration uses.
