Use REST API to sync data between multiple databases

Applies to: Azure SQL Database

Important

SQL Data Sync will be retired on 30 September 2027. Consider migrating to alternative data replication/synchronization solutions.

This REST API example configures SQL Data Sync to sync data between multiple databases.

For an overview of SQL Data Sync, see What is SQL Data Sync for Azure?

SQL Data Sync does not support Azure SQL Managed Instance or Azure Synapse Analytics.

Create sync group

Use the create or update template to create a sync group.

When creating a sync group, do not pass in the sync schema (table\column) and do not pass in masterSyncMemberName, because sync group does not have table\column information.

Sync group names cannot contain special characters, but can contain letters, numbers, underscore (_), dash (-).

The minimum interval time for group synchronization is five seconds. If the interval time is smaller, five seconds will be used.

Sample request for creating a sync group:

PUT https://management.azure.com/subscriptions/00000000-1111-2222-3333-444444444444/resourceGroups/syncgroupcrud-65440/providers/Microsoft.Sql/servers/syncgroupcrud-8475/databases/syncgroupcrud-4328/syncGroups/syncgroupcrud-3187?api-version=2015-05-01-preview

    "interval": -1,

    "hubDatabaseUserName": "hubUser"
  }
}

Create sync member

Use the create or update template to create a sync member.

Refresh schema

Once your sync group is created successfully, refresh schema using the following templates.

Use the refresh hub schema template to refresh the schema for the hub database.

Sample request for refreshing a hub database schema:

POST https://management.azure.com/subscriptions/00000000-1111-2222-3333-444444444444/resourceGroups/syncgroupcrud-65440/providers/Microsoft.Sql/servers/syncgroupcrud-8475/databases/syncgroupcrud-4328/syncGroups/syncgroupcrud-3187/refreshHubSchema?api-version=2015-05-01-preview

Sample response for refreshing a hub database schema:

Status code: 200

Status code: 202

Use the list hub schemas template to list the hub database schema.

Use the refresh member schema template to refresh the member database schema.

Use the list member schema template to list member database schema.

Only proceed to the next step once your schema refreshes successfully.

Update sync group

Use the create or update template to update your sync group.

Update sync group by specifying the sync schema. Include your schema and masterSyncMemberName, which is the name that holds the schema you want to use.
