Passing multiple query parameters to Rest API

Summary:

Hi All, I am trying to pass multiple query parameters to Worker Rest API. I have tested the same in postman and it is working as expected. But I get 400 error when I map it through OIC.

Content (required):

Working Postman Get ALL Call - https://fusionurl/hcmRestApi/resources/11.13.18.05/workers?q=externalIdentifiers.ExternalIdentifierNumber=400090 &q=externalIdentifiers.ExternalIdentifierType=PERSONID

When I try to include '&' in RestAPI mapper, it returns as '&'. I tried passing 'and' but it failed to return any data.

Below is the screenshot of query parameters written in mapper of Rest API.

Please let me know the correct way to pass multiple query parameters.
