How to Update Contacts — Hubspot Connector for C#

Introduction

In this article we will delve deeper into Hubspot and C# integration, and will learn how to update contacts. We are continuing from where we left off. By this time, you must have created ODBC Data Source and connected to Hubspot. So, let's not waste time and begin.

Use Query Builder to generate SQL query

The first thing you have to do is open Query Builder:

ZappySys API Driver - Hubspot

Hubspot Connector can be used to integrate Hubspot and your data source, e.g. Microsoft SQL Server, Oracle, Excel, Power BI, etc. Get, write, delete Hubspot data in a few clicks!

HubspotDSN
Then simply select the Contacts table and Update operation.
Continue by configuring the Required parameters. You can also set optional parameters too.
Move on by hitting Preview Data button to preview the results.

If you see the results you need, simply copy the generated query:

Contacts

Update

This Endpoint has no parameters.

UPDATE Contacts
SET firstname = 'Brian'
   ,lastname = 'Halligan (Sample Contact)'
   --,custom_number=12.12
   --,custom_date='2023-01-01'
   --,custom_string='My Test<<FUN_NOW>>'
   --,custom_richtext='<p><span style="color: #b5b5b5;">##-Please reply-##</span></p>'
   --,custom_multi_select='Blue;Yellow;Black'
   --,custom_pickuser=45581955
   --,custom_dropdown='BB'
   --,custom_checkbox='true'   
WHERE Id = 51

That's it! You can use this query in C#.

Let's not stop here and explore SQL query examples, including how to use them in Stored Procedures and Views (virtual tables) in the next steps.

SQL query examples

Use these SQL queries in your C# data source:

Updates contacts in your account

UPDATE Contacts
SET firstname = 'Brian'
   ,lastname = 'Halligan (Sample Contact)'
   --,custom_number=12.12
   --,custom_date='2023-01-01'
   --,custom_string='My Test<<FUN_NOW>>'
   --,custom_richtext='<p><span style="color: #b5b5b5;">##-Please reply-##</span></p>'
   --,custom_multi_select='Blue;Yellow;Black'
   --,custom_pickuser=45581955
   --,custom_dropdown='BB'
   --,custom_checkbox='true'   
WHERE Id = 51

How to Update multiple records - (BULK read / write from external source)

This examples shows how to perform bulk update using SOURCE clause. It reads data from external system (in this example MS SQL Server) and sends data to Hubspot using Bulk API

UPDATE Contacts 
SOURCE(
  'MSSQL' --ODBC or OLEDB
  ,'Data Source=localhost;Initial Catalog=Test;Integrated Security=true'
  ,'select 104811 as Id, ''new-email1@abc.com'' as email
    UNION 
    select 104812 as Id, ''new-email2@abc.com'' as email
)

update_contacts endpoint belongs to Contacts table(s), and can therefore be used via those table(s).

Stored Procedures and Views

Create Custom Stored Procedure

You can create procedures to encapsulate custom logic and then only pass handful parameters rather than long SQL to execute your API call.

Steps to create Custom Stored Procedure in ZappySys Driver. You can insert Placeholders anywhere inside Procedure Body. Read more about placeholders here

Go to Custom Objects Tab and Click on Add button and Select Add Procedure:
Enter the desired Procedure name and click on OK:
Select the created Stored Procedure and write the your desired stored procedure and Save it and it will create the custom stored procedure in the ZappySys Driver:
Here is an example stored procedure for ZappySys Driver. You can insert Placeholders anywhere inside Procedure Body. Read more about placeholders here
```
CREATE PROCEDURE [usp_get_orders]
    @fromdate = '<<yyyy-MM-dd,FUN_TODAY>>'
 AS
    SELECT * FROM Orders where OrderDate >= '<@fromdate>';
```
That's it now go to Preview Tab and Execute your Stored Procedure using Exec Command. In this example it will extract the orders from the date 1996-01-01:
```
Exec usp_get_orders '1996-01-01';
```
Let's generate the SQL Server Query Code to make the API call using stored procedure. Go to Code Generator Tab, select language as SQL Server and click on Generate button the generate the code.
As we already created the linked server for this Data Source, in that you just need to copy the Select Query and need to use the linked server name which we have apply on the place of [MY_API_SERVICE] placeholder.
```
SELECT * FROM OPENQUERY([LS_TO_HUBSPOT_IN_GATEWAY], 'EXEC usp_get_orders @fromdate=''1996-07-30''')
```
Now go to SQL served and execute that query and it will make the API call using stored procedure and provide you the response.

Create Custom Virtual Table

ZappySys API Drivers support flexible Query language so you can override Default Properties you configured on Data Source such as URL, Body. This way you don't have to create multiple Data Sources if you like to read data from multiple EndPoints. However not every application support supplying custom SQL to driver so you can only select Table from list returned from driver.

If you're dealing with Microsoft Access and need to import data from an SQL query, it's important to note that Access doesn't allow direct import of SQL queries. Instead, you can create custom objects (Virtual Tables) to handle the import process.

Many applications like MS Access, Informatica Designer wont give you option to specify custom SQL when you import Objects. In such case Virtual Table is very useful. You can create many Virtual Tables on the same Data Source (e.g. If you have 50 URLs with slight variations you can create virtual tables with just URL as Parameter setting.

Go to Custom Objects Tab and Click on Add button and Select Add Table:
Enter the desired Table name and click on OK:
And it will open the New Query Window Click on Cancel to close that window and go to Custom Objects Tab.
Select the created table, Select Text Type AS SQL and write the your desired SQL Query and Save it and it will create the custom table in the ZappySys Driver:
Here is an example SQL query for ZappySys Driver. You can insert Placeholders also. Read more about placeholders here
```
SELECT
  "ShipCountry",
  "OrderID",
  "CustomerID",
  "EmployeeID",
  "OrderDate",
  "RequiredDate",
  "ShippedDate",
  "ShipVia",
  "Freight",
  "ShipName",
  "ShipAddress",
  "ShipCity",
  "ShipRegion",
  "ShipPostalCode"
FROM "Orders"
Where "ShipCountry"='USA'
```
That's it now go to Preview Tab and Execute your custom virtual table query. In this example it will extract the orders for the USA Shipping Country only:
```
SELECT * FROM "vt__usa_orders_only"
```
Let's generate the SQL Server Query Code to make the API call using stored procedure. Go to Code Generator Tab, select language as SQL Server and click on Generate button the generate the code.
As we already created the linked server for this Data Source, in that you just need to copy the Select Query and need to use the linked server name which we have apply on the place of [MY_API_SERVICE] placeholder.
```
SELECT * FROM OPENQUERY([LS_TO_HUBSPOT_IN_GATEWAY], 'EXEC [usp_get_orders] ''1996-01-01''')
```
Now go to SQL served and execute that query and it will make the API call using stored procedure and provide you the response.

Update Contacts in C#

We are at the point where we can reiterate on how to use the SQL query, Stored Procedures or Views in C#:

Create a new Console project and use this code to read the data:

"HubspotDSN";
Press F5 to run the code and read the data:

Here is the code in text format:

using System;
using System.Data.Odbc;

namespace ConsoleApp {
    class Program {
        static void Main() {
            var dsn = "HubspotDSN";
            using (var conn = new OdbcConnection(String.Format("DSN={0}", dsn)))
            {
                conn.Open();
                var cmd = new OdbcCommand("SELECT * FROM Products", conn);
                
                //Increase the timeout duration from the default 30 seconds, which may be insufficient in certain scenarios
                cmd.CommandTimeout=600; // 600-Seconds
                
                var rdr = cmd.ExecuteReader();
                while (rdr.Read())
                {
                    for (int i = 0; i < rdr.FieldCount; i++)
                    {
                            Console.Write("{0}\t", rdr[i]);
                    }
                    Console.WriteLine();
                }
            }
            Console.ReadKey();
        }
    }
}
