# Third-party agent

> Call an AI agent that runs on another platform, such as Databricks, Google Vertex, Microsoft Azure AI Foundry, Salesforce Agentforce, or Snowflake Cortex.

**Third-party agent** lets a workflow call an AI agent that runs on another platform. The workflow sends the agent a task, and continues with its answer.

## Add a third-party agent

1. Select **+** on the handle of the node it follows, then select **Agent > Third-party agent**.
2. Pick the agent's action. The list is grouped by platform, and [Actions](#actions) lists every action.
3. In the properties panel, select a connection to that platform, or create one. [Create a connection](create-a-connection.md) describes how to create one.

Each action has its own fields, which appear in the properties panel after you select a connection.

## Actions

| Platform | Action | What it does |
|---|---|---|
| Databricks Agent | **Query a Serving Endpoint** | Send a request to a serving endpoint, with an input schema that's generated for you. |
| Databricks Agent | **Query a Serving Endpoint (Manual)** | Send a request to a serving endpoint, with JSON input that you enter yourself. |
| Google Vertex | **Execute Google Vertex Agent** | Run a Google Vertex AI reasoning engine agent. |
| Microsoft Azure AI Foundry | **Execute the Thread** | Run a thread with an Azure AI Foundry agent. |
| Microsoft Azure AI Foundry | **Invoke Agent** | Send a message to an Azure AI Foundry agent and get its response. |
| Salesforce Agentforce & Flows | **Execute Salesforce Agent** | Run a Salesforce agent. |
| Snowflake Cortex | **Interact Agent** | Send a query to a Cortex Agent object and get its response as a stream of events. |
| Snowflake Cortex | **Run Agent Without an Agent Object** | Run a Cortex agent without creating an agent object first. |

## Next steps

- [Autonomous agent](node-agent.md): build an agent on the canvas instead.
- [Coded agent](node-coded-agent.md): call an agent that a developer wrote in code.
- [Community](community.md): ask questions and share workflows with other builders on the UiPath Forum.
