Hi @john john Pter,
Thank you for posting in this community.
I tested your first Rest API. I was able to get the items correctly. I checked your Rest API without problems.
I suggest clearing the cache and retesting.
Or I suggest you test your request directly through Internet Explorer, although the return value of the page is hard to read. However, we can read the return value through the Xml parser. This is the most direct way to check if your Rest API is correct. (Since I can't use post man, this is how I tested it.)
Attached is the Rest API I used.
https://{site url}/_api/web/lists/getbytitle('ListName')/items?$filter=(DestinationItemID2 eq 'b!B_cp4O1z3UWJZwD0nLlCD30PN0T59jBInsAjZKgerapT_CbZ-9oRS7oTEHC0zg-T.01DZCLQ3ZMKDHIM6B27ZHK2POEGQXSSXGX') and (ListName eq 'Zoho') and (ReadCount eq 2)
Here is my test result:
