Azure firewall setup

By default, Azure protects your SQL Server from any external IP address from connecting to your SQL Server. Follow these steps to add Hightouch's IP addresses to the firewall:

  1. Log into your Azure Console Dashboard.
  2. Click on SQL databases under Services.
  3. Select the SQL database you want to update.
  4. Select Set server firewall .
    Azure Console Dashboard with settings
  5. Under Public network access, select Selected networks.
    Azure Console Dashboard with settings
  6. Scroll to Firewall rules and click Add a firewall rule.
    Azure Console Dashboard with settings
  7. Allowlist the Hightouch IP addresses for your region.
  8. Click the Save button on the bottom left.

Required permissions

Both setup options require:

  • Server name (IP address or Azure hostname)
  • Port number (1433 by default)
  • Database name
  • SQL Server Username
  • SQL Server Password

Your credentials must be able to:

  • Add/update/delete rows in your sync's table.
  • View these tables: (*These are used for gathering metadata to set up the sync.)

To ensure your credentials are correct, click Test connection. This will confirm if Hightouch is able to properly connect to your database by running a simple SELECT query.

Password form

Connection string

Connection string must be in this format: Server=server;Database=database;User Id=username;Password=password;Encrypt=boolean


Hightouch supports Upsert mode with the option to delete removed rows.

Select the schema and table you want to sync to. A common schema to use is the database's default, dbo.

Record matching

Records can be matched from your source to your database table using any primary key or unique column. Hightouch only shows columns that are of the PRIMARY KEY or UNIQUE type in the dropdown.

Note: We do not display IDENTITY columns as those can't be edited or set when inserting.

Field mapping

Select the fields from your source that you want to sync to SQL Server.

Make sure you account for column types and columns that are non-nullable. If you upsert any row with the wrong column type or set a null value for a non-nullable column, the entire batch with that row (up to 1k rows) will fail.

Tips and troubleshooting

Common errors

If you encounter an error or question not listed below and need assistance, don't hesitate to . We're here to help.

Cannot open server 'hightouch-test' request by login

If you see the following error message, you need to update your firewall settings in your Azure Console.

Cannot open server 'hightouch-test' request by login. Client with IP address '' is not allowed to access the server. To enable access, use the Windows Azure Management Portal or run sp_set_firewall_rule on the master database to create a firewall rule for this IP address or address range. It may up take up to five minutes for this change to take effect.
