Replicate Multiple MailerLite Accounts via the CData Sync CLI

CData Sync for MailerLite is a stand-alone application that provides solutions for a variety of replication scenarios such as replicating sandbox and production instances into your database. Both Sync for Windows and Sync for Java include a command-line interface (CLI) that makes it easy to manage multiple MailerLite connections. In this article we show how to use the CLI to replicate multiple MailerLite accounts.

Configure MailerLite Connections

You can save connection and email notification settings in an XML configuration file. To replicate multiple MailerLite accounts, use multiple configuration files. Below is an example configuration to replicate MailerLite to SQLite:

Windows

<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync>
  <DatabaseType>SQLite</DatabaseType>
  <DatabaseProvider>System.Data.SQLite</DatabaseProvider>
  <ConnectionString>Profile=C:\profiles\MailerLite.apip;ProfileSettings='APIKey=your_api_key';</ConnectionString>
  <ReplicateAll>False</ReplicateAll>
  <NotificationUserName></NotificationUserName>
  <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
  <TaskSchedulerStartTime>09:51</TaskSchedulerStartTime>
  <TaskSchedulerInterval>Never</TaskSchedulerInterval>
</CDataSync>

Java

<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync>
<DatabaseType>SQLite</DatabaseType>
  <DatabaseProvider>org.sqlite.JDBC</DatabaseProvider>
  <ConnectionString>Profile=C:\profiles\MailerLite.apip;ProfileSettings='APIKey=your_api_key';</ConnectionString>
  <ReplicateAll>False</ReplicateAll>
  <NotificationUserName></NotificationUserName>
  <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
</CDataSync>

Set the ProfileSettings connection property to the connection string for MailerLite (see below).

MailerLite API Profile Settings

Obtain your API Key from the Integrations page in your MailerLite account dashboard.

Configure Queries for Each MailerLite Instance

Sync enables you to control replication with standard SQL. The REPLICATE statement is a high-level command that caches and maintains a table in your database. You can define any SELECT query supported by the MailerLite API. The statement below caches and incrementally updates a table of MailerLite data:

REPLICATE Account;

You can specify a file containing the replication queries you want to use to update a particular database. Separate replication statements with semicolons. The following options are useful if you are replicating multiple MailerLite accounts into the same database:

You can use a different table prefix in the REPLICATE SELECT statement:

REPLICATE PROD_Account SELECT * FROM Account 

Alternatively, you can use a different schema:

REPLICATE PROD.Account SELECT * FROM Account

Run Sync

After you have configured the connection strings and replication queries, you can run Sync with the following command-line options:

Windows

APISync.exe -g MyProductionAPIConfig.xml -f MyProductionAPISync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar APISync.jar -g MyProductionAPIConfig.xml -f MyProductionAPISync.sql
