There may be times where you'd like to assign ownership of a record using the likes of zip code/postal code. Often in situations like these there are hundreds if not thousands of values. The code snippets below show how you can solve for this using Operations Hub Professional.

assignOwnerUsingZipOption1.js

/*
 * This code snippet first gets a reference to the contacts postal code. Then it checks a series of arrays for the value. Each
 * array represents a reps territory or region. When a match is found we assign the HubSpot Owner ID value to a variable and
 * pass this back to the workflow using the callback object. You are then able to copy this value into the "HubSpot Owner"
 * property.
 /
exports.main = async (event, callback) => {

    // Store contact postal code in variable
    const zip = event.inputFields['zip'];
    let owner; // will store the user ID of the owner

    // Create arrays for each rep to hold assigned postal codes
    const rep1 = ["1", "2", "3", "4"];
    const rep2 = ["5", "6", "7", "8"];
    const rep3 = ["9", "10", "11", "12"];

    // Check which rep the postal code is assigned to 
    if (rep1.includes(zip)) { // Rep 1
        console.log("Assign rep 1");
        owner = "246804692";
    } else if (rep2.includes(zip)) { // Rep 2
        console.log("Assign rep 2");
        owner = "321450460";
    } else if (rep3.includes(zip)) { // Rep 3
        console.log("Assign rep 3");
        owner = "321450461";
    } else { // If no match assign Rep 4
        console.log("Assign rep 4");
        owner = "321450462"
    }

    // Pass the data back to the workflow so we can copy to owner property
    callback({
        outputFields: {
            "owner": owner
        }
    })
}

assignOwnerUsingZipOption2.js

/*
 * This code snippet is similar to the above but instead rather than using the callback object we use the CRM API to update
 * the "HubSpot Owner" property. This code snippet first gets a reference to the contacts postal code. Then it checks a series of
 * arrays for the value. Each array represents a reps territory or region. When a match is found we store the HubSpot Owner ID value
 * to a variable and call the HubSpot Contact CRM API to update the "hubspot_owner_id" property.
