REST Web Services API on Obs endpoint

Web-services REST API

version 2.24.0

Currently this REST API allows you to do a get request on Obs table by passing concept together with patient uuid parameters, however how can i query the obs table with only concept and value parameters while using this API. And if not possible , what are the reasons for this restrictions.

Can you explain, with some bit of details, about the use case that you are trying to address?

Am trying to count the number of observations with a certain concept and a particular value without considering the patient. For example to get observations with concept = 48AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA and valueCoded = 1065AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA, my urlbe would be From the documentation about the obs endpoint, this is not possible. It only recommends that you use the concept in combination with the patient . e.g patient = patientUuid& concept=conceptUuid&valueCoded=codeUuuid. So my question is on how else to get observations with concept uuid and value parameters as it is in the first url.
