FAQ

What information do I need to provide?

Please provide the target app name (already provided), specific requirements (e.g., transaction details, real-time quotes, payment channels), and whether you have backend credentials or a test environment.

What is the typical delivery timeline?

Depends on the complexity of the interfaces; typically 5–12 business days for the first API and documentation delivery; real-time quotes or multi‑exchange integrations may take longer.
