    }
]

This is what i am trying but getting an error:

const jsonData = pm.response.json();

pm.test('Has data', function() {
  pm.expect(jsonData).to.have.property('id');
});

I want to verify - id, givenName, logo, createdAt, UpdatedAt, tags and all are present and want to make a global function so in other tests I can just call it once

To fix your error, try to loop through your array of object i.e jsonData like below. By the way I didn't play with postman global function creation. Hope this link will help you on how to make/use it as global How to Write Global Functions in Postman

pm.test('Has data', () => {
  jsonData.forEach(row => {
    pm.expect(row).to.have.property('id');
    pm.expect(row).to.have.property('givenName');
    pm.expect(row).to.have.property('logo');
    pm.expect(row).to.have.property('createdAt');
    pm.expect(row).to.have.property('updatedAt');
    pm.expect(row).to.have.property('tags');
  })    
});

For checking all parameters in response you should consider using built-in tv4.validate, which stands for Tiny Validator (for v4 JSON Schema) - it validates simple values and complex objects against provided schema.

In your particular case you would do something like this:

const jsonData = pm.response.json(); 

const schema = {
  items: {
    type: "object",
    properties: {
        id: {type: "string"},
        givenName: {type: "string"},
        logo: {type: "string"},    
        createdAt: {type: "string"},
        updatedAt: {type: "string"},
        tags: {type: "array"}
    },
    required:["id","givenName","logo", "createdAt", "updatedAt", "tags"]
  }
};

pm.test('Schema is valid', () => pm.expect(tv4.validate(jsonData, schema)).to.be.true);

More examples of how to use tv4 can be found in its repo.
