Salesforce Integration – External Data Sources

Connecting external System by Clicks


Salesforce offers a variety of mechanisms inbuilt for connecting external systems in real time. SOAP, REST and a variety of integration adapters are available out of the box to push/pull data to/from external systems. Salesforce introduces External Data Sources which enables systems to integrate.

Salesforce provides a variety of adapters to connect with external systems. The available adapters are

  1. Salesforce Connect: OData 2.0

  2. Salesforce Connect: OData 4.0

  3. Federated Search: OpenSearch

  4. Outgoing Email

  5. Recommendation

  6. Salesforce Connect: Cross-Org

  7. Simple URL

For current demo, Integration will be performed to connect between salesforce Orgs using Salesforce Connect: Cross-Org option.


  1. Salesforce sandboxes

Integration Overview:

In current example, Integration will be performed by connecting Salesforce sandbox orgs to push/pull a custom object records. Custom object data will be pulled from Source system. Once integrated, data can be updated any of the system and changes will be reflected in other system. (???????)

Salesforce also uses the adapters below to connect and integrate tables (?????????) from SAP NetWeaver Gateway, Microsoft Dynamics NAV, and many other data sources in real time

  • OData 2.0 adapter or OData 4.0 adapter: connects to data exposed by any OData 2.0 or 4.0 producer on the Internet. OData (Open Data Protocol) is a modern, REST-based protocol for integrating data. Vendors such as SAP and Microsoft have already implemented OData support, so products such as NetWeaver and SharePoint are directly accessible. Integration products from Salesforce partners extend the reach of Salesforce Connect to a much wider range of back-office systems.
  • Cross-org adapter: Connects to data that’s stored in another Salesforce org. The Cross-org adapter uses the standard REST API. It directly connects to the other org without the need of an intermediary web service, as is the case with OData.
  • Custom adapter created via Apex: if the OData and cross-org adapters aren’t suitable for your needs, develop your own adapter with the Apex Connector Framework.
