Nash docs

Build on deliveries in motion

One API to orchestrate last-mile delivery across 80+ providers and your own fleet — and an agent that makes every delivery smarter than the last.

How Nash works Create your first order Authentication What's new
Platform Documentation Model your operation — orders, jobs, dispatch strategies, zones, and webhooks — and let Nash pick the right provider for every delivery.
Copilot Nash Agent An operations copilot that investigates, acts with your sign-off, and analyzes — scoped to your organization and your permissions.
Reference API Reference Every endpoint, request, and response — orders, jobs, quotes, routes, zones, and the rest. With an OpenAPI spec you can hand to an LLM.

Start building

Plan your integration →
Grab an API key and organization ID from the [Nash portal](/reference/generating-api-key-and-org-id), and build against the [sandbox environment](/reference/environments) until you're ready. One request with a pickup and a dropoff. Nash validates the addresses and returns quotes from eligible providers. [Select a quote](/api-reference/order/select-quote) yourself, or [autodispatch](/api-reference/order/autodispatch-order) and let your [dispatch strategy](/reference/dispatch-strategies) decide. Subscribe to [webhooks](/reference/webhooks) and every status change — assignment, pickup, dropoff — comes to you.
```bash curl theme={"dark"} curl -X POST https://api.sandbox.usenash.com/v1/order \ -H "Authorization: Bearer $NASH_API_KEY" \ -H "Nash-Org-Id: $NASH_ORG_ID" \ -H "Content-Type: application/json" \ -d '{ "externalId": "order-4f2a", "pickupAddress": "210 King St, San Francisco, CA 94107", "dropoffAddress": "1 Ferry Building, San Francisco, CA 94111" }' ``` ```javascript Node theme={"dark"} const res = await fetch("https://api.sandbox.usenash.com/v1/order", { method: "POST", headers: { Authorization: `Bearer ${process.env.NASH_API_KEY}`, "Nash-Org-Id": process.env.NASH_ORG_ID, "Content-Type": "application/json", }, body: JSON.stringify({ externalId: "order-4f2a", pickupAddress: "210 King St, San Francisco, CA 94107", dropoffAddress: "1 Ferry Building, San Francisco, CA 94111", }), }); const order = await res.json(); // order.quotes — priced quotes from eligible providers ``` ```python Python theme={"dark"} import os import requests res = requests.post( "https://api.sandbox.usenash.com/v1/order", headers={ "Authorization": f"Bearer {os.environ['NASH_API_KEY']}", "Nash-Org-Id": os.environ["NASH_ORG_ID"], }, json={ "externalId": "order-4f2a", "pickupAddress": "210 King St, San Francisco, CA 94107", "dropoffAddress": "1 Ferry Building, San Francisco, CA 94111", }, ) order = res.json() # order["quotes"] — priced quotes from eligible providers ```

The Nash-Org-Id header is required when your API key has access to more than one organization. Get your org ID →
