Safety & migration

Phase 4 utilities — secret masking, required-field validation, and a one-click upgrade path from legacy v1 connections into the universal v2 connector.

Secrets are masked

When the connector wizard reads a saved connection, all known secret keys (passwords, client_secret, tokens, HMAC secrets, API keys) are returned as••••last4. The raw value stays on the server and is only used at request-time.

Migrate v1 connections to v2

Copies base URL + best-effort auth detection into the universal connector. The v1 record stays in place — nothing is deleted.

Mapping validation

Static checks before you run a job: required fields, target table, post mode, aggregation prerequisites.
