Steps
Authenticate by sending your API key in the X-API-KEY header on every request over HTTPS/TLS 1.3.
Create an order via the orders endpoint (see dashboard.gelato.com/docs/orders/v3/create/), batching up to 100 items in a single order submission.
Retrieve product catalog and pricing data before order creation to confirm SKUs, sizing, and print options are valid for the target product line.
Subscribe to webhooks for real-time order, production, and shipment status changes rather than only polling the orders endpoint.
Respect the documented rate limit of up to 100 requests/second per API key, with retry/backoff logic for bursts.
Known gotchas
Tracking numbers and carrier info are only populated once an order actually ships -- don't expect them immediately after creation.
Large multi-item orders (up to 100 items) still count as a single API call for rate-limit purposes, so batch where possible instead of looping single-item calls.
