# Markets & locales

> How the app-market and app-locale headers shape every Airzone Control API response.

Two headers control regionalization across the **entire** API:

* **`app-market`** — selects the regional catalog and availability rules.
* **`app-locale`** — selects the language of the response content.

Send both on every request.

## Markets

Use the `app-market` value that matches your client's region.

| Code | Market                  |
| ---- | ----------------------- |
| `eu` | Europe                  |
| `ib` | Spain                   |
| `ff` | France                  |
| `it` | Italy                   |
| `na` | North America           |
| `de` | Deutschland             |
| `pt` | Portugal                |
| `an` | Australia – New Zealand |
| `as` | Asia                    |
| `gb` | Great Britain           |
| `ie` | Ireland                 |
| `me` | Middle East             |
| `af` | Africa General          |
| `la` | Latin America           |
| `en` | Europe Non TAU          |
| `nf` | North Africa            |
| `aa` | Rest of the World       |

<Warning>
  Heads up on `en`: as an **`app-market`** value it means *Europe Non TAU*, but as an **`app-locale`** value it means *English*. They are different headers — don't confuse them.
</Warning>

## Locales

Use the `app-locale` value for the response language.

| Code | Language   |
| ---- | ---------- |
| `en` | English    |
| `es` | Spanish    |
| `fr` | French     |
| `de` | German     |
| `it` | Italian    |
| `pt` | Portuguese |

## Finding the right codes

If you are unsure which market or locale code to use for a given country, the region picker maps each country and language to the corresponding values:

<Steps>
  <Step title="Open the region picker">
    Go to [airzonecontrol.com/aa/en/region-picker](https://www.airzonecontrol.com/aa/en/region-picker).
  </Step>

  <Step title="Select a country and a language">
    Pick the country and language, then select **Continue**.
  </Step>

  <Step title="Read the codes from the URL">
    You are redirected to `https://www.airzonecontrol.com/{market}/{locale}/`. Use those `{market}` and `{locale}` values as your `app-market` and `app-locale` headers.
  </Step>
</Steps>

<Tip>
  Example: a redirect to `https://www.airzonecontrol.com/eu/en/` means `app-market: eu` and `app-locale: en`.
