1. Install MySQL Server: If you haven’t already, install MySQL on your server or local machine. You can download it from the official MySQL website.
2. Create a Database: Log into your MySQL server and create a new database where you will store the HubSpot data:
   ‍CREATE DATABASE hubspot_data;‍
3. Create Tables: Define the structure of the tables that will hold the data you want to import from HubSpot. Ensure that the schema matches the data you’ll be extracting.
   USE hubspot_data;
CREATE TABLE contacts (
   id INT PRIMARY KEY,
   firstname VARCHAR(255),
   lastname VARCHAR(255),
   email VARCHAR(255),
   -- Add other fields as necessary
);

1. Get HubSpot API Key: Log into your HubSpot account, navigate to the API key section, and generate an API key if you haven’t done so already.
2. Plan Your API Calls: Determine which endpoints you’ll need to use to extract the necessary data. For example, you might use the Contacts API to get contact information.
3. Write a Script to Call the HubSpot API: You can use a programming language like Python to write a script that makes requests to the HubSpot API. Here’s a sample Python script using the requests library:
import requests
import json

HUBSPOT_API_KEY = 'your_api_key'
ENDPOINT = 'https://api.hubapi.com/contacts/v1/lists/all/contacts/all'
PARAMS = {
   'hapikey': HUBSPOT_API_KEY
}

response = requests.get(ENDPOINT, params=PARAMS)
data = response.json()
contacts = data['contacts']

# Extract the relevant data from the contacts
# You might need to handle pagination if there are many contacts‍
4. Handle Pagination: HubSpot’s API might paginate the data, so ensure your script handles this by looping through all pages of data.
5. Extract and Format Data: Convert the extracted data into a format suitable for insertion into your MySQL database, such as a list of dictionaries or a CSV file.

1. Connect to MySQL: Use a MySQL client library in your chosen programming language to connect to your MySQL database. For Python, you can use mysql-connector-python or PyMySQL.
   import mysql.connector
cnx = mysql.connector.connect(
   user='your_username',
   password='your_password',
   host='127.0.0.1',
   database='hubspot_data'
)
cursor = cnx.cursor()
2. Prepare Insert Statements: Write a function or a script to insert the formatted data into your MySQL tables. Be cautious about SQL injection and use parameterized queries.
   add_contact = ("INSERT INTO contacts "
              "(id, firstname, lastname, email) "
              "VALUES (%s, %s, %s, %s)")

for contact in contacts:
   contact_data = (contact['id'], contact['firstname'], contact['lastname'], contact['email'])
   cursor.execute(add_contact, contact_data)

cnx.commit()
3. Handle Data Types and Encoding: Ensure that the data types from the API match the corresponding MySQL column data types. Also, handle any character encoding issues.
4. Error Handling: Implement error handling in your script to manage any issues that arise during the data transfer process, such as connection problems or data inconsistencies.
5. Close Connections: After the data has been successfully inserted, close the cursor and the connection to the MySQL database.cursor.close()
cnx.close()

1. Test the Script: Run your script in a controlled environment first to ensure it works as expected. Test with a small subset of data if possible.
2. Validate the Data: After running the script, check the MySQL database to confirm that the data has been correctly inserted and that there are no discrepancies.
3. Optimize Performance: Depending on the volume of data, you might need to optimize your script and MySQL queries for better performance.

If you need to keep the MySQL database in sync with HubSpot data regularly, you can schedule the script to run at specific intervals using cron jobs (on Linux) or Task Scheduler (on Windows).
