Frequently asked questions
Which systems can you connect?
Common projects include CRM, payments, messaging, ecommerce, and calendars. Custom APIs are supported when documentation is available.
Do you prefer webhooks or polling?
We prefer event-driven webhooks when available, with verification and retries. Polling is used when an API requires it.
How do you keep integrations secure?
Secrets stay in environment configuration, tokens follow least privilege, and access is limited to required scopes. Logging is added when needed.
What happens when an external API is down?
We design retries, idempotency where possible, and operator alerts so work is not silently lost.
