API Playground

Every endpoint below sends a real request from your own browser — nothing is proxied through us. Paste your API key once and it's reused across every panel.

Sandbox pre-fills the free test GSTIN and turns on test_mode for e-way bill / e-invoice calls, so nothing is charged or actually filed.
