> [!NOTE]
> This page:
> * Gives an example on working with the `metapolicy_struct` field.
> * Covers code samples in Node.js and Python.
> * Uses the <b>Retrieve hotel dump</b> call:
>   * [B2B](/docs/b2b-api/static-content/retrieve-hotel-dump/).
>   * [Affiliate](/docs/affiliate-api/static-content/retrieve-hotel-dump/).



> [!TIP]
> * Change the `unspecified` values to something that will work for you.
> * Change other values to a readable format.
> * Make sure you process nullable or empty objects.
