The Detail Level field is used to set which level of details will returned in Search Hotels response.
The different detail levels are :

👍

NOTE:

• Using the first three Detail Levels: Default, Low, or Minimal:
  Gets all data in the search results, and by using these options, there is no option to call GetPackages.
  Doing this is unrecommended as it is very resource consuming and bandwidth-heavy, as all the packages show up in the search results.
• Feel free to try the different detail levels and see what works best for your specific situation and users.
  However, if you just want to get started, we recommend using:
  1. MetaExtended - as it is lightweight and returns all of the commonly needed fields. (Without Hotel data)
  2. MetaAdvanced - In case you need the Hotel data in the Search response.

⭐

IMOPRTANT NOTE !

To obtain the starred (⭐) parameters - Suppliers must provide room information during the Search step.

For suppliers who return room information in a separate call, the filtering options will not be available because this information is missing from the search step.
