How to Expose ServiceNow AI Agent Studio Agent as A2A Server for External Platform Integration?

[maryammousa]

Hello ServiceNow Community,

I have built an AI agent using ServiceNow AI Agent Studio (on Yokohama release with Now Assist). I now want to expose this ServiceNow agent as an A2A (Agent2Agent) compliant server so that external platforms (like Google ADK agents, Salesforce Agentforce, or custom Python agents) can discover and communicate with my ServiceNow agent via the A2A protocol.

What I'm trying to achieve:

• Register/expose my ServiceNow AI Agent Studio agent as an A2A server
• Make it discoverable with an AgentCard at /.well-known/agent.json
• Allow external agents to send messages to my ServiceNow agent via A2A protocol endpoints

Questions:

1. Does ServiceNow AI Agent Studio automatically expose agents as A2A servers, or do I need additional configuration?
2. What is the URL/endpoint structure for accessing my ServiceNow agent via A2A?
3. Are there any prerequisites or properties I need to enable?

Any guidance, documentation links, or examples would be greatly appreciated!

Hi Warren , 

We tried the payload provided but we are getting a 400 bad request error , Also we are not able to switch the default asynchronous execution for A2A to synchronous in setting page in AI Agent studio

Latest Update on A2A :

With A2A protocol support, your Now Assist AI Agents can share data, context, and action to collaborate on objectives. Now Assist AI Agents can act as either the primary (orchestrating) agent that calls upon external agents; or it can act as a secondary (invoked) agent to an external AI Agent.

Quick APIs Details for Agent Discovery and execution

• Also note that ServiceNow A2A has separate endpoints for Agent Card discovery and Agent Execution. Additionally, as of December 2025, there is a V2 version for each endpoint:
  • (GET) Agent Card V1: /api/sn_aia/a2a/id/{agent_id}/well_known/agent_json
  • (GET) Agent Card V2: /api/sn_aia/a2a/v2/agent_card/id/{agent_id}
  • (POST) Agent Execution V1: /api/sn_aia/a2a/v1/agent/id/{agent_id}
  • (POST) Agent Execution V2: /api/sn_aia/a2a/v2/agent/id/{agent_id}

Please help to make the agent execution synchronous or fix the asynchronous payload ,what should be the callback url if we are testing locally ?
