Building a custom Gemini Enterprise connector for Salesforce

Google Cloud Build with AI Agents
1

My usecase is building a custom salesforce connector that can be used by Gemini Enterprise users. For iDP we used Google workspace based authentication / native Google Identity Platform

I am reading this documentation link about building a custom connector. What is not clear is the authentication and authorization part. From what i understand both the GE app end user and the custom connector needs to get authenticated and authorized.

The heading “ACLs and Identity mapping” in the above link mentions 2 methods to setup Authn and Authz. Is PureACLs the way to go for my use case since I am using google workspace account as an iDP?

Also link does not mention the deployment options for the custom connector. I know GCP marketplace is the ideal solution but we want to release it as a private connector. Do i need to package the connector code as a Cloud Run service?

Note:- The custom connector would be ingestion based not federated so any recommendations here

I believe this is based on how the integration works for the Salesforce, are they using specific user_id on the resources or email addresses!

Now the problem is what kind of connector are you building? is it based on the official salesforce api? What kind of export official salesforce api supports? Because custom data stores works in a way of storing documents with metadata, i’m sure custom connector is more like federated way.

Are you using any MCP for this integration? I’m also really interested in implementing something internally, but couldn’t find a cool way. it’s really painful to integrate salesforce afaik!

Have you checked it out this one → Connect Salesforce  |  Gemini Enterprise  |  Google Cloud Documentation

Btw, V2 explicitly requires a Salesforce Enterprise or Developer plan; trial orgs are not supported.
