Hi @User_XSUGG ,

The invalid_request response usually means one of the request inputs does not match what the AI Agent Team REST endpoint expects.A few things to validate:

1. Use the real v2 endpoint, not the placeholder version:

POST https://<fusion-host>/api/fusion-ai/orchestrator/agent/v2/<AgentTeamCode>/invokeAsync

1. Make sure <AgentTeamCode> is the Agent Team Code from AI Agent Studio, and that the version and status match the published agent team.
2. Send Content-Type: application/json and pass the OAuth bearer token generated with the Fusion AI scope:

Authorization: Bearer <access_token>
Content-Type: application/json

1. Use a valid JSON payload. For passing parameters, put them inside the parameters object:

{
"message": "Run the agent for this request",
"conversational": true,
"version": 6,
"status": "PUBLISHED",
"parameters": {
"employeeNumber": "12345",
"fromDate": "2026-05-01",
"toDate": "2026-05-31"
}
}

Also check that the calling user/application has access to the agent team. In AI Agent Studio, the role must be added under the Agent Team Security tab, then the agent team must be updated and published.

Arindam.
