Unenrols from every proposition, and deletes the site and assets in accordance with data retention policies. Use when the user is leaving entirely — for example, they've moved house, or your support team is removing them. Payments can no longer be accessed afterwards. If the user is only opting out of one proposition (e.g. toggling Flex Lite off in your app), use `unenrol` instead — it preserves the site and any other propositions they're enrolled in. ## OpenAPI ````yaml POST /entities/site/{site_id}/offboard-site-and-assets openapi: 3.1.0 info: title: Axle API Docs description: >- For full documentation please see our official docs at docs.axle.energy version: 1.4.6 servers: - url: https://api-sandbox.axle.energy security: [] tags: - name: 1.
