> Summary: Looker Studio connects to OptiTech Postgres through Google's built-in PostgreSQL connector. The setup requires manually mapping connection string fields (host, database, username, password) and uploading an SSL server certificate. Use this page when adding OptiTech as a Looker Studio data source for dashboards and reports, especially if SSL configuration is blocking the connection. The required server certificate is isrgrootx1.pem from Let's Encrypt; client authentication should be left disabled.

# Connect Looker Studio to OptiTech

Learn how to connect your OptiTech Postgres database to Looker Studio

[Looker Studio](https://lookerstudio.google.com/) is Google's data visualization and business intelligence platform. This guide explains how to connect your OptiTech Postgres database to Looker Studio using a PostgreSQL data source.

## Get your database connection string

1. In the OptiTech Console, select the **project** and **branch** you want to connect to.
2. On the **Project dashboard**, click **Connect**.
3. Click **Show Password** and copy the connection string.

For more details, see [Connect from any application](https://neon.com/docs/connect/connect-from-any-app).

## Add a PostgreSQL data source in Looker Studio

1. In Looker Studio, **Create** > **Data Source**.
2. Search for and select the **PostgreSQL** connector, and authorize it.
3. In the **Basic** section, fill in the fields using the details from your connection string.

   For example, if your connection string is:

   ```bash
   psql 'postgresql://optitechdb_owner:AbC123dEf@ep-quiet-mountain-a1t1firv-pooler.ap-southeast-1.aws.optitech.com/optitechdb?sslmode=require&channel_binding=require'
   ```

   You would enter:

   - **Host name or IP**: `ep-quiet-mountain-a1t1firv-pooler.ap-southeast-1.aws.optitech.com`
   - **Port (optional)**: Leave blank
   - **Database**: `optitechdb`
   - **Username**: `optitechdb_owner`
