Synchronizing business systems is a common practice for organizations managing large volumes of customer and operational data. HubSpot and PostgreSQL are two platforms often used together to support this effort.
HubSpot is used for managing customer interactions, including marketing, sales, and support activities. PostgreSQL is used to store structured data in a format that supports complex querying and reporting.
Bringing data from HubSpot into PostgreSQL allows teams to work with customer data in a structured environment. This process supports internal reporting, data validation, analytics, and integration with other systems.
Two-way synchronization, also called bidirectional sync, is a method where data flows in both directions between systems. When information changes in either system, the update is reflected in the other system automatically.
Unlike one-way sync (which only moves data from a source to a destination), two-way sync creates a continuous data loop between platforms. This ensures both systems contain the same information at all times.
For example, in a HubSpot to PostgreSQL two-way sync:
When a sales rep updates a contact in HubSpot, the information appears in PostgreSQL
When an analyst modifies customer data in PostgreSQL, the changes appear in HubSpot
This bidirectional flow eliminates data silos and keeps information consistent across business systems.
HubSpot is a cloud-based CRM platform used to track and manage customer relationships. PostgreSQL is an open-source relational database that stores large volumes of structured data.
These systems complement each other because HubSpot excels at user-friendly data collection, while PostgreSQL provides powerful data analysis capabilities. When connected through proper synchronization, they create a more complete data ecosystem.
The benefits of HubSpot database integration with PostgreSQL include:
Centralized analytics: Combine marketing data with information from other business systems
Enhanced reporting: Create custom reports beyond what HubSpot offers natively
Technical accessibility: Make CRM data available to database administrators and analysts
This PostgreSQL CRM sync works particularly well in organizations where multiple departments need access to the same customer information.
There are three primary approaches to creating a two-way sync between HubSpot and PostgreSQL. Each method offers different levels of automation, technical complexity, and maintenance requirements.
ETL (Extract, Transform, Load) and ELT (Extract, Load, Transform) tools are specialized software designed to move data between systems. These tools handle the technical aspects of connecting to APIs, mapping fields, and scheduling updates.
Popular options include:
Tool | Real-time Capability | Setup Complexity | Bidirectional? | Cost Range |
|---|---|---|---|---|
Fivetran | Yes | Medium | No | $$ |
Stitch | No | Low | No | $ |
Stacksync | Yes | Low | Yes | $$$ |
Talend | No | High | Yes | $$ |
ETL tools work by extracting data from the source system (HubSpot), transforming it to match the destination format, and loading it into the target system (PostgreSQL). For true two-way sync, the process runs in both directions, with conflict resolution rules to handle simultaneous updates.
This basic approach involves manually exporting data from one system and importing it into the other. While simple, it requires significant human intervention and doesn't support real-time updates.
The process works like this:
Export contacts, companies, or deals from HubSpot as CSV files
Use PostgreSQL's COPY command to import the data:
COPY customers(email, first_name, last_name)
FROM '/path/to/contacts.csv'
DELIMITER ','
CSV HEADER;
To complete the two-way sync, export from PostgreSQL and import back to HubSpot
This method is time-consuming and error-prone. It's suitable only for occasional updates or very small datasets.
Developers can create custom scripts that connect directly to HubSpot's API and PostgreSQL. This approach offers the most flexibility but requires programming knowledge and ongoing maintenance.
A basic Python example might look like:
import requests
import psycopg2
# Get data from HubSpot
response = requests.get(
'https://api.hubapi.com/crm/v3/objects/contacts',
headers={'Authorization': 'Bearer YOUR_API_KEY'}
)
# Connect to PostgreSQL and insert data
conn = psycopg2.connect("dbname=database user=username")
cursor = conn.cursor()
# Insert logic here
Custom integrations can support real-time, two-way synchronization by using webhooks or regular polling to detect changes in either system.
Creating a dependable bidirectional synchronization between HubSpot and PostgreSQL involves several key steps. This process ensures data flows correctly in both directions without errors or conflicts.
The first step is mapping the data structure between systems. This involves identifying which HubSpot objects (contacts, companies, deals) correspond to which PostgreSQL tables.
For example:
HubSpot Object | PostgreSQL Table | Key Fields |
|---|---|---|
Contacts | customers | email, first_name, last_name |
Companies | accounts | company_name, domain, industry |
This HubSpot PostgreSQL schema design creates a blueprint for how data will flow between systems. It's important to account for data types, field lengths, and required fields to prevent errors during synchronization.
Both HubSpot and PostgreSQL require proper authentication for secure access. For HubSpot, this means creating a private app in the developer portal to generate an API key or OAuth token.
PostgreSQL requires database connection credentials, including:
Host address
Port number
Database name
Username
Password
These credentials should be stored securely and never hardcoded directly in scripts or configuration files.
For efficient two-way synchronization, the system needs to identify which records have changed since the last sync. There are several approaches to change detection:
Timestamp tracking: Use "last modified" dates to find recently updated records
Version numbers: Increment a counter each time a record changes
Checksums: Calculate a hash value based on record contents to detect changes
This change data capture process is essential for real-time HubSpot PostgreSQL sync because it prevents unnecessary data transfers and reduces API usage.
When data can change in both systems, conflicts inevitably occur. A conflict happens when the same record is modified in both HubSpot and PostgreSQL before synchronization occurs.
Conflict resolution strategies include:
Last-writer-wins: The most recent change takes precedence
Source priority: One system is designated as authoritative for certain fields
Manual resolution: Conflicts are flagged for human review
For example, a sales team might decide that contact information updated in HubSpot always overrides changes in PostgreSQL, while financial data from PostgreSQL takes priority over HubSpot.
Proper conflict handling is essential for bidirectional HubSpot PostgreSQL sync to maintain data integrity and prevent information loss.
As data volumes grow, synchronization performance becomes increasingly important. Several techniques can improve the efficiency of two-way sync between HubSpot and PostgreSQL.
Instead of synchronizing all data during each cycle, incremental updates focus only on records that have changed since the last sync. This approach significantly reduces processing time and API usage.
A simple SQL query to find recently modified records might look like:
SELECT * FROM customers WHERE updated_at > '2023-06-01 00:00:00';
By synchronizing only changed records, the system can handle larger datasets without performance degradation.
Grouping records into batches improves efficiency when working with HubSpot's API. Instead of making individual API calls for each record, batch processing allows multiple records to be updated in a single request.
This technique reduces the number of network connections and helps stay within API rate limits. Most ETL tools automatically implement batching to optimize HubSpot PostgreSQL integration.
Regular monitoring helps identify and resolve synchronization issues before they impact business operations. Key metrics to track include:
Sync completion time
Number of records processed
Error rate
API quota utilization
When problems occur, detailed logs make it easier to troubleshoot HubSpot PostgreSQL sync issues. Common problems include network timeouts, schema mismatches, and authentication failures.
Organizations implement bidirectional synchronization between HubSpot and PostgreSQL for various business purposes. These real-world applications demonstrate the practical value of two-way sync.
Marketing analytics: Marketing teams use HubSpot to track campaign performance, while data analysts use PostgreSQL to combine this information with data from other channels. Two-way sync ensures both teams work with the same information.
Customer service: When support representatives update customer information in HubSpot, the changes automatically appear in operational databases. This ensures that all customer-facing teams have access to current information.
Product development: Usage data stored in PostgreSQL can be synchronized with HubSpot to help sales and marketing teams identify upsell opportunities and target specific customer segments.
These automated HubSpot PostgreSQL data sync implementations eliminate manual data entry and reduce the risk of inconsistent information across systems.
Two-way synchronization between HubSpot and PostgreSQL creates a seamless data flow that benefits multiple departments within an organization. By keeping customer information consistent across systems, teams can make better decisions based on accurate, up-to-date data.
The key to successful bidirectional sync is choosing the right implementation approach based on technical resources, data volume, and business requirements. Whether using ETL tools, custom API integration, or a hybrid approach, proper planning prevents synchronization problems.
As data becomes increasingly central to business operations, effective two-way sync between systems like HubSpot and PostgreSQL will remain an essential component of a modern data infrastructure.
One-way synchronization transfers data in a single direction from a source to a destination. Two-way synchronization transfers data in both directions, keeping both systems updated with changes from either side.
The optimal frequency depends on business needs. Real-time or near-real-time sync (every few minutes) works best for operational data, while daily synchronization is sufficient for analytical purposes.
Yes, custom objects can be synchronized using HubSpot's Custom Objects API. This requires creating corresponding tables in PostgreSQL with matching fields for each custom property.
Most synchronization systems use soft deletes (flagging records as inactive) or track deletion events to ensure that when a record is deleted in one system, it's also removed from the other system.
Secure two-way sync implementations use encrypted connections (SSL/TLS), API authentication, database access controls, and audit logging to protect data during transfer and storage.
