REST API + eCardWidget questions
Where do I get an API key?

Yes. Every account has a sandbox mode that mirrors production endpoints and simulates deliveries without charging or sending real eCards.
What's the rate limit?
10,000 requests per hour per API key on the free tier, higher on paid plans. Rate-limit headers are returned on every response.
