FAQ

Developer FAQs

Where to start, how docs relate to APIs, and deploying with us.

Where should I start if I'm new?

Open Getting Started, make a health-check request with a sandbox key, then pick an API from the marketplace that matches your use case.

Is documentation separate from the marketplace?

Marketplace product pages cover overview and pricing. Each API also has docs for endpoints. The Documentation hub covers broader guides and platform topics.

Can I deploy my app with LesterTechLabs?

Yes — Lester PaaS is our developer cloud for Git-based deploys, managed databases, and SSL close to your users.
