Resolving the issue:

For the custom REST API that is accessible to all user types (Guest, Generic and Registered)

(a)    Go to the folder Rest/WebContent/WEB-INF/config/com.ibm.commerce.rest-ext

(b)   Create a new file wc-rest-security.xml under this folder.

(c)    Place the below entry into the file

<security>

<partialAuthentication enabled="true" resource=<REST URL> method="GET"/>

</security>

For e.g, if your custom REST API is as below

   http://<hostname>/wcs/resources/store/{storeId}/get_tax?taxid=1000

<security>

<partialAuthentication enabled="true" resource=”store/{storeId}/get_tax” method="GET"/>
