Questions

What if a service has no API?

We look at other options: exports, webhooks or direct exchange with the database. If there is no legal and reliable way, we say so right away.

Who pays for external services?

Plans and limits of external services are usually paid by you and stay on your accounts.

What happens when an external service changes its API?

We set up failure alerts. Updates can be included in support.
