## title: Environments

Rendr provides two fully isolated API environments. Use UAT for development and testing, and Production for live traffic.

<CardGroup cols={2}>
  <Card title="UAT" icon="duotone flask" href="#uat-user-acceptance-testing">
    Safe, isolated environment for integration development, testing, and validation.
  </Card>

  <Card title="Production" icon="duotone rocket" href="#production">
    Live environment for real carrier bookings, dispatch, and financial settlement.

## Base URLs

  <Card title="Production" icon="duotone rocket">

<Note>
  All API paths are identical across environments. Only the base URL changes.

## Environment Isolation

Environments are completely separated — nothing is shared between them.

## UAT (User Acceptance Testing)

UAT is intended for integration development and pre-production validation.

**Use UAT for:**

<CardGroup cols={3}>
  <Card title="Integration Development" icon="duotone code">
    Build and iterate against a safe, non-live environment.
  </Card>

  <Card title="End-to-End Testing" icon="duotone list-check">
    Validate full delivery flows without real-world impact.
  </Card>

  <Card title="Status Lifecycle Testing" icon="duotone arrows-spin">
    Walk through status transitions in a controlled environment.
  </Card>

  <Card title="Store Configuration" icon="duotone store">
    Set up and test store rules before going live.
  </Card>
</CardGroup>

**Characteristics:**

* Safe for repeated testing
* Test deliveries do not trigger real financial settlement
* Carrier integrations operate in sandbox or controlled test mode
* Rate limits may differ from Production

<Tip>
  Always validate your integration in UAT before promoting changes to Production.
</Tip>

## Production

Production processes live deliveries with real carriers and real customers.

**Characteristics:**

* Real carrier bookings
* Real dispatch and tracking
* Financial settlement may apply
* Operational monitoring enabled

<Warning>
  Only Production API keys can access the Production environment.
