ADK Agent to ADK Agent

[Rajavelu]

Hi,

I created two multi agents in two different gcp project.
Now i want to create a orchestrator agent in one gcp project and call both agents .

Kindly guide me the best approach/steps for this.

@Rajavelu There are some samples for ADK agent to agent communication in the following sample repos:

https://github.com/google/adk-samples
https://github.com/a2aproject/a2a-samples

[Rajavelu]

@ericdong  can i create single agent like root agent and keep other agents as sub agents or A2A ? which one is advisable?

[ericdong]

@Rajavelu yes you can. Using ADK multi-agent will give you more flexibility as posed to using A2A in your case.

Hi @Rajavelu,

Welcome to the Google Cloud Community!

In addition to @ericdong, you can set up an Orchestrator Agent that uses a webhook hosted on Cloud Function or Cloud Run to invoke Child Agents via the Dialogflow API. This lets you programmatically handle cross-project communication by forwarding user input, managing authentication, preserving session state, and delegating intents to the appropriate agent.

You may want to check the following documentation for more information.
