Credits apply to API operations that perform an action — generating a document, converting a file, or sending an envelope. Requests that only upload or pass data don't consume credits. Most PDF Services and Document Generation calls cost 1 credit; one eSign envelope costs 5. You can confirm usage in your dashboard.

Frequently Asked Questions
Everything you need to understand credits, eSign, and renewal.
One envelope uses 5 credits, flat. That covers the full signing lifecycle — sending, embedded signing sessions, tracking, and retrieving the completed document. Status checks and webhooks don't consume credits.
Every self-serve plan includes eSign, PDF Services, Document Generation, and PDF Embed under one account-level plan with shared credits. You can activate eSign from your dashboard and start building your signature workflow right away — for higher volumes or custom packaging, talk to sales.
API calls that require credits stop processing until your credits renew or you upgrade your plan. You'll get alerts before you exhaust your credits and can monitor usage in your dashboard, so you have time to upgrade or adjust before your workflow stops.
Yes. Billing is annual and you can upgrade at any time as usage grows. Credits reset when they renew rather than rolling over, and your plan is account-level — usable across multiple projects and apps. If you need a higher-volume plan, talk to sales and we'll align a plan for your expected usage.
