## Best Practices

* **Keep users informed:** Explain when external data is being fetched and why
* **Ensure compliance:** Always get user consent for sensitive data (tax, company, ID)
* **Combine smartly:** For example, CVR Lookup + ESKAT + PDF Signature = full B2B application flow
* **Close strong:** End flows with clear next steps (download, book a meeting, continue elsewhere)

***

## Example Recipes

**B2B Onboarding**\
Message → CVR Lookup → ESKAT Data → PDF Generation → PDF Signature → Action (Create account)

**Support Request**\
Message → GitHub Issue → Slack Trigger (Notify support team) → Chat End
