Use REST API to sync data between multiple databases

[!INCLUDEappliesto-sqldb]

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

For an overview of SQL Data Sync, see Sync data across multiple cloud and on-premises databases with SQL Data Sync in Azure.

Important

SQL Data Sync does not support Azure SQL Managed Instance at this time.

Create sync group

Use the following template to create a sync group: https://docs.microsoft.com/rest/api/sql/syncgroups/createorupdate When creating a sync group, do not pass in the sync schema (table\column) and do not pass in masterSyncMemberName, because at this time sync group does not have table\column information yet.

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

{
  "properties": {
    "interval": -1,
    "lastSyncTime": "0001-01-01T08:00:00Z",
    "conflictResolutionPolicy": "HubWin",
    "syncDatabaseId": "/subscriptions/00000000-1111-2222-3333-444444444444/resourceGroups/syncgroupcrud-3521/providers/Microsoft.Sql/servers/syncgroupcrud-8475/databases/syncgroupcrud-4328",
    "hubDatabaseUserName": "hubUser"
  }
}

Sample response for creating a sync group:

Status code: 200

Refresh schema

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

Refresh schema for hub: https://docs.microsoft.com/rest/api/sql/syncgroups/refreshhubschema

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:

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