Why use mocked APIs before live integrations?

Fixtures prove success, failure, timeout, retry, duplicate webhook, and outage behavior before vendor quotas, credentials, or customer records are exposed.

How do you prevent duplicate writes?

Use idempotency keys, payload hashes, provider ids, attempt logs, dedupe windows, and state-machine processing for external writes and webhooks.

Can Closeaim integrate HubSpot and analytics safely?

Yes. HubSpot receives contact and routing detail server-side, while GA4/GTM receive only safe event names, categories, source fields, and counts.

What happens when a provider is down?

Retry policy, circuit breakers, fallback queues, operator alerts, and manual reconciliation views should be defined before launch.
