Replicate Multiple eBay Accounts

Replicate multiple eBay accounts to one or many databases.

CData Sync for eBay 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 eBay connections. In this article we show how to use the CLI to replicate multiple eBay accounts.

Configure eBay Connections

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

Windows

<?xml version="1.0" encoding="UTF-8" ?> <CDataSync> <DatabaseType>SQLite</DatabaseType> <DatabaseProvider>System.Data.SQLite</DatabaseProvider> <ConnectionString>AppId=MyAppId;CertId=MyCertId;DevId=MyDevId;SiteId=MySiteId;RuName=MyRuName;CallbackURL=http://localhost:33333;</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>AppId=MyAppId;CertId=MyCertId;DevId=MyDevId;SiteId=MySiteId;RuName=MyRuName;CallbackURL=http://localhost:33333;</ConnectionString> <ReplicateAll>False</ReplicateAll> <NotificationUserName></NotificationUserName> <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString> </CDataSync>

If you will be accessing your own account, you can generate an OAuthAccessToken from your developer account dashboard. You can also allow other users to securely access their own accounts.

Both of these methods require you to create an application key set to obtain values for the following connection properties: AppId, CertId, DevId, and SiteId.

The user consent flow additionally requires the RuName and CallbackURL.

See the "Getting Started" chapter in the help documentation for a guide to using OAuth.

Configure Queries for Each eBay 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 eBay API. The statement below caches and incrementally updates a table of eBay data:

REPLICATE ItemListing;

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 eBay accounts into the same database:

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

REPLICATE PROD_ItemListing SELECT * FROM ItemListing

Alternatively, you can use a different schema:

REPLICATE PROD.ItemListing SELECT * FROM ItemListing

Run Sync

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

Windows

EbaySync.exe -g MyProductionEbayConfig.xml -f MyProductionEbaySync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar EbaySync.jar -g MyProductionEbayConfig.xml -f MyProductionEbaySync.sql
