Live 1Courier rates at checkout.

Install the official 1Courier app and your Shopify store instantly gains carrier-calculated rates for every GTA address. Same-day and next-day options appear at checkout with the exact all-in CAD price. When a customer picks one, the order books with us automatically. Tracking links and photo POD push back into Shopify so your customers see them in their account.

First-party — built and maintained by 1Courier, not a third-party connector. Updates ship through the Shopify App Store automatically; install once and you're covered. No extra subscription fee, no middleman to babysit.

Public API · v1 (stable)

Public API for ecommerce.

REST + JSON over HTTPS. Idempotency keys on every write, HMAC-signed webhooks for every status change. Sandbox is free forever — same surface as production with dummy drivers and synthetic ETAs. No credit card required to get a key.

POST https://api.1courier.com/v1/quote
Authorization: Bearer sk_live_XXX
Idempotency-Key: qt_8xK2A

{
  "pickup":   { "address": "100 King St W, Toronto" },
  "dropoff":  { "address": "7025 Markham Rd, Markham" },
  "weight_lbs": 3,
