Workflow Examples

Vendor Onboarding Pipeline

Validate a new vendor's address, tax ID, bank account, and screen against sanctions lists — all in one workflow.

Manual Trigger → QubitOn (Address Validate) → QubitOn (Tax Validate) → QubitOn (Bank Validate) → QubitOn (Sanctions Screening) → IF (any failed?) → Slack Alert

Daily Sanctions Re-screening

Run nightly sanctions re-screening on all active vendors from your database.

Cron (daily) → Postgres (get vendors) → SplitInBatches → QubitOn (Sanctions Screening, requestType=Re-check) → IF (matches found?) → Email Alert

Healthcare Provider Compliance

Validate NPI, check exclusion lists, and run sanctions screening for healthcare providers.

Spreadsheet → QubitOn (NPI Validation) → QubitOn (Healthcare Exclusion Check) → QubitOn (Sanctions Screening) → Google Sheets (results)

Error Handling

The node surfaces API errors as n8n execution errors. Enable Retry On Fail in node settings for transient errors:

| HTTP Status | Cause | Resolution | |-------------|-------|------------| | 400 | Missing required fields | Check that all required input fields are mapped | | 401 | Invalid API key | Update your QubitOn API credential | | 429 | Rate limit exceeded | Enable retry with 1-second wait between tries | | 500 | Server error | Enable retry with exponential backoff |

For batch processing, use the SplitInBatches node to process items in groups and avoid rate limits.
