Grab a $0 sandbox key and place a real, idempotent order against the live API — then watch it ship on real signed webhooks. Pick your stack below. Every framework guide is plain REST, no SDK required.
The whole loop runs on a test key, for $0, before you ever touch a production order.
Create a free account and copy a ps_test_ key. Sandbox orders cost $0 and never charge a card.
One authenticated POST to /order — validated, priced, and routed. Send an Idempotency-Key so retries never double-charge.
The sandbox runs the full lifecycle on a compressed clock, firing real HMAC-signed webhooks at every status change.
Each guide places a $0 sandbox order and verifies a signed webhook in your framework of choice. Prefer another language? Any HTTP client works against the REST API.
App Router with server actions. Keep your API key server-side and stream order status into React.
Get startedA minimal Node server that forwards orders and verifies signed webhooks with a thin fetch helper.
Get startedOrder management with the requests library. Works the same with Django or FastAPI.
Get startedA service class, controller, and routes with HMAC webhook verification built in.
Get startedA lightweight HTTP client and handlers for high-throughput order processing.
Get startedThe same first order — a sandbox key, a real SKU, a tracking link that delivers — in curl, TypeScript, Python or PHP. TypeScript runs on fetch and Python on the standard library, with nothing to install; PHP needs only its curl extension, nothing from Composer.
