1

Get your API key

Grab an API key and organization ID from the Nash portal, and build against the sandbox environment until you’re ready.
2

Create an order

One request with a pickup and a dropoff. Nash validates the addresses and returns quotes from eligible providers.
3

Dispatch it

Select a quote yourself, or autodispatch and let your dispatch strategy decide.

Listen for what happens next

Subscribe to webhooks and every status change — assignment, pickup, dropoff — comes to you.
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 '{

    "pickupAddress": "210 King St, San Francisco, CA 94107",

  }'

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

Quote at checkout, confirm at payment, dispatch on fulfillment — the integration most teams ship first.

Route optimization

Turn a pile of orders into sequenced, capacity-aware routes — then dispatch them as one.

Production testing

Simulate provider behavior end-to-end before a single real courier is dispatched.
