Graph Connector Agent

This lightweight app is the platform that takes care of orchestration capabilities and coordinates between Microsoft 365 admin center and customer's connector code. More on the software: Graph Connector Agent | Microsoft Docs.

Get Started

1. Install GCA and follow the instructions to register the agent Graph Connector Agent | Microsoft Docs.

2. Download the protocol buffer files with gRPC contracts.

3. Protobuf compiler downloaded and extracted from here (Not needed if using Visual Studio).

   • Environment path updated with bin folder in extracted root.
   • Compile contracts to create server-side stubs in the language of your choice. More info here.

4. Create a project in your IDE and place all the proto files in a folder named "Contracts". Sample project structure here:

   

5. Implement methods in the stubs generated by the compiler.

6. Create a server, run the application and generate the executable/output binaries.

7. Edit the CustomConnectorPortMap JSON file in the GCA installation folder (Program files > Graph connector agent) with connector id (same as provider id) and TCP port information (port on which you are running the server).

   • You may need to open notepad/VS in admin mode to edit the JSON.

8. Test the connector code via TestApp.

9. Create a custom connector connection on Microsoft Admin Center.
