JSON Codeless Data Integration and Synchronization

Data provided by JSON-based web services and apps can be kept in sync code-free across 150+ typically used IT systems, on-premises or in the cloud, with the help of the Layer2 Cloud Connector Enterprise Edition. Microsoft Office 365, SharePoint, SQL, Dynamics, Exchange, or Azure is supported as well as SQL/ERP/CRM systems of many vendors. You will find supported systems and applications here.


Benefits of JSON Data Integration and Synchronization

Data integration and synchronization of JSON-based web services can provide the following features and benefits with the help of the Layer2 Cloud Connector.

Your JSON data available everywhere, at any time, on any device, or app

Connect it code-free and keep your pre-selected local or cloud-based JSON service data in sync with 150+ IT systems. Make use of all features of the certain target system, such as search, forms, and workflows (SharePoint).

Fast implementation and low risk in project

No programming is required. Just install the connector on a Windows server in your network, in your own cloud, or even on your laptop, and adapt predefined sample connection templates. Just in case you will need any help with the installation, you can make use of our Free Quick Start Service.

Direct secure connections with full control

The data synchronization runs as Windows service locally in your network, or in your own cloud. No 3rd party, vendor, or cloud service are involved. You don't even have to make changes in the connected systems or in your network.

Keep your JSON data in sync, one-way or even two-way

In general, this connector allows the write-back of data changes made in the connected system to your local or cloud-based JSON service in the case if it's required, authorized, and technically supported by the service. The connector works great if you want to add cross-system business processes to your JSON services, such as Microsoft SharePoint workflows or actions in PowerApps, Flow, or Azure Logic Apps.

Flexible data synchronization features for your business

Advanced features can make the difference: Flexible field mapping, Dynamic Columns to apply data cleanup, calculations, data transformation, and data translation between the connected systems to implement custom business logic in C# are possible. 

No hidden costs with licensing and maintenance

There are no additional costs per connected system, connection, number of transferred items, or data volume.

All Layer2 Cloud Connector are licensed per installation. While the Personal Edition has a one-time fee licensing, the List and Table Edition and Enterprise Edition are based on an annual subscription.

  • Data aggregation: Multiple connections can combine several different JSON data queries into one list.
  • Flexible logging and alerts: You can log to files, databases, and Windows Event Log via NLOG.
  • Free Edition: You can test the Free Edition as long as you want or you can use in production with limited features. You can upgrade the Free Edition to a licensed version at any time without new installation.

How it works

See the screens below to get the idea how it works. Note, that connecting a JSON Web Service to Office 365 and SharePoint is just an example. You can connect JSON-based data sources to any supported system.



JSON Specific Configuration Settings

Please note the following about JSON-specific settings.


  • Please select the JSON Provider in the list.
  • Best to start with a free JSON test site:

  • Please start with the following:

  • Please set the primary key.
  • Bi-directional sync is generally supported by the Layer2 Cloud Connector and also by the JSON data provider. Please make sure that a primary key is defined for this.

Examples of JSON Data Integration Scenarios implemented via Layer2 Cloud Connector


You will find typical use cases here:


  • Connect your JSON-based service with any SQL database for better reporting.
  • Use SharePoint Online as a front-end to your JSON service.
  • Connect and sync JSON with OData-based services.
  • Push JSON data, such as contacts, to Microsoft Exchange for mobile and offline access on any device (BYOD).
  • Connect JSON data to SharePoint Online lists to make it available on any device via Microsoft apps for Windows, iOS, and Android.
  • Create Microsoft PowerApps based on JSON-connected SharePoint lists or SQL tables.
  • Keep your Microsoft Teams or Office Groups users notified about pre-selected JSON data changes directly in Teams channels. Provide JSON data as a connected list in Microsoft Teams.
  • Start workflows in Microsoft Flow or Azure Logic Apps on JSON data changes.

JSON Data Integration - Known Issues and Workarounds


  • For more complex JSON content note the "JSON Path" parameter in the connection string.
  • Bi-directional synchronization is generally supported. Your JSON service must allow writing for this. You also need to have write access rights for two-way sync.
  • Blobs, binary fields such as used to store images or documents in database tables are not supported by the data provider.
  • Complex SharePoint fields like lookups, user or group picker etc. are generally supported. You have to make sure providing values that fit into the fields. You can use the Dynamic Columns feature of the Layer2 Cloud Connector to translate values across systems.

Frequently Asked Questions (FAQ)

Please find answers to frequently asked questions about JSON data integration below.

What about authentication to the JSON service?

While you can generally use authentication as usual with the Layer2 Cloud Connector (e.g. Windows, Basic, or integrated), typically API-keys and/or Application-keys are provided in the url or connection string to grant access to the service.

Where to define my insert, update, and delete statements

You don't have to define any insert, update or delete statements to keep the connected systems in sync. The data providers will generate it automatically during runtime based on your JSON data and your primary key(s).
