What counts as one "file" against my daily limit?

Each job you submit (one ECU file processed) counts as one file against your daily limit, regardless of how many solutions you apply to it.

What happens if I hit my daily API limit?

Further submissions that day return a clear message asking you to upgrade or wait until the next day. Nothing is charged for blocked requests. You can upgrade anytime for a higher limit.

Which API plan should a busy workshop pick?

If you process a steady flow, Business (500 files/day) fits most resellers. High-volume operations with many sub-clients should take Enterprise (unlimited).

How many websites can I use per API subscription?

Each plan includes a set number of registered websites — Starter 1, Business 3, Enterprise 10. You add and remove them yourself in your profile API settings, up to your plan limit. The API only delivers to your registered sites and webhooks must be on one of them.

Do I need a separate account to use the API?

No — it uses your existing DaVinci Deluxe · Cloud Edition account. The API plan is just a separate subscription on top.

What happens if I stop paying for the API?

Access is automatically revoked when the subscription ends and all API keys stop working. You can resubscribe anytime.

Which ECUs and brands does the Cloud Tuning API support?

Coverage is ECU-specific. See the full list on the developer docs; if a service is not available for a file, the job is rejected with a clear reason and never charged.

Is the Cloud Tuning API asynchronous?

Yes. Poll the status endpoint, or set a webhook URL and we POST a signed callback the moment the file is ready.

Can you build the whole API integration for me?

Yes. The 1000€ Integration service connects the API into your existing website. For 1500€ we build you a complete website with the Cloud Tuning service fully integrated and automated end-to-end. Both include 6 months of support and updates (API subscription billed separately).

Is annual API billing cheaper?

Yes — annual plans give you 2 months free versus paying monthly.

Do you offer refunds on the API?

No. All API subscriptions and one-time services are billed in advance and are non-refundable, including partial periods, unused daily file capacity, and any time left after you cancel. Cancelling stops future renewals only.
