Why sync Medusa to PostgreSQL?
Ready for analysis.

Centralizing your Medusa data in PostgreSQL lets you join it with other data sources for cross-platform analytics and deeper insights.

Build reliable dashboards and reports by querying Medusa data directly in PostgreSQL using SQL or your preferred BI tool.

  • Revenue and order analytics

    Track orders, products, and customer behavior from Medusa in PostgreSQL. Build cohort analyses, LTV models, and inventory forecasting.

  • Centralized data warehouse

    Bring Medusa data into PostgreSQL alongside other sources to create a single source of truth for your organization.

  • Automated reporting

    Replace manual exports and spreadsheet-based reporting with automated pipelines from Medusa to PostgreSQL. Connect BI tools like Looker, Metabase, or Power BI.

Data

What data can you sync?
From Medusa to PostgreSQL.

Weld syncs the objects the Medusa connector exposes into PostgreSQL, and you choose which tables and fields to include. The connector's docs list what is available.

    Weld MCP server

    Ask your agent.
    It queries PostgreSQL for you.

    Connect Claude, Cursor, ChatGPT or your own agent to Weld over MCP. It reads the Medusa context, finds the tables it needs and runs the query in PostgreSQL.

    Under the hood

    Technical considerations.
    What to expect.

    Incremental syncing
    Weld uses incremental syncing where supported by the Medusa API, loading only new and updated records to minimize data transfer and warehouse costs.
    Schema handling
    Weld automatically manages schema changes. If Medusa adds new fields, they're detected and added to the corresponding PostgreSQL tables.
    Data freshness
    Sync frequency depends on your Weld plan. Most connectors support schedules from every 5 minutes up to daily intervals.
    Security
    All data is encrypted in transit (TLS) and at rest. Weld is SOC 2 Type II compliant and supports IP whitelisting for database connections.
