# AWS (RDS)
## Step 1: Find your database
Navigate to the AWS RDS dashboard. In the left panel you should see "Databases":
Databases page
In this list, select your database:
Database list in RDS
## Step 2: Construct the connection URI
On the main database page, you should have the "Connectivity & security" tab selected. Note the endpoint and port number:
RDS endpoint and port number
Next under the "Configuration" tab, look up the username. You can also create a different user for Whalesync to connect, but for simplicity we'll use the master username:
RDS configuration with the username
The password was set when the database was originally created. Please ask whoever set up the database for the connection password.
Finally, construct the connection URI like this and replace `YOUR_PASSWORD` with the password:
{% code overflow="wrap" %}
```
postgresql://postgres:YOUR_PASSWORD@postgres-connector-test.000000000000.us-east-1.rds.amazonaws.com:5432/postgres
```
{% endcode %}
This is the string you will paste into the Whalesync Postgres connection dialog:
Enter your Postgres connection URI into Whalesync
## Caveats
Note that Whalesync does not yet support:
* Whitelisted IP addresses
* Custom SSL/TLS certificates
If you need these to connect to your instance, please [reach out and let us know](/resources/support.md).
