Response Example : 
Main":{"Error":{"Code":110,"Message":"MissingArrivalDateElement"},"DebugError":{"Incident":0,"TimeStamp":"2025-09-19 17:50:57","Message":"Missing 'ArrivalDate' Element under 'Root/Main'"

What it means : 

Your Search request does not include the ArrivalDate element, which is mandatory to perform a hotel search.

Common reasons

• <ArrivalDate> tag is completely missing from the XML.

• Typo in the tag name (e.g., <ArriveDate> or any other incorrect word instead of <ArrivalDate>).

  Resolution / How to fix : 

• Add <ArrivalDate> with a valid date in YYYY-MM-DD format.

  • Example: <ArrivalDate>2025-11-19</ArrivalDate>

• Make sure the tag name is spelled exactly as <ArrivalDate> and is placed inside <Root><Main>.
