Can any referencing entity attribute be updated using "/api/data/v9.0"?

Question

I want to update _parentcustomerid_value in the Contact entity (and some other) but I face such a problem - The property provided was of type System.Object, when the expected was of type System.Guid I used this link to update entity attributes. Can anyone suggest me what to do? Maybe I'm doing something wrong or it's not possible to update ids.

For lookup attribute, you have to use single valued navigation property and not the lookup property.

entity["[email protected]"] = "/contacts(DFE54660-37CD-E511-80DE-6C3BE5A831DC)" 

Reference

The full code will look like this:

// define the data to update a record
var data =
    {
        "[email protected]": "/contacts(DFE54660-37CD-E511-80DE-6C3BE5A831DC)"
    }
// update the record
Xrm.WebApi.updateRecord("contact", "61a0e5b9-88df-e311-b8e5-6c3be5a8b200", data).then(
    function success(result) {
        console.log("Contact updated");
        // perform operations on record update
    },
    function (error) {
        console.log(error.message);
        // handle error conditions
    }
);
