# Set up Agent-to-Agent (A2A)

<Badge icon="arrow-left" color="gray">[Back to protocols channel](/agent-platform/channels#protocols)</Badge>

Supports the Google A2A protocol for inter-agent communication with task lifecycle management.

To configure an Agent-to-Agent (A2A) channel, go to **Deployments** > **Channels** > **Agent-to-Agent (A2A)** > **+ New** and complete the following steps in order.

<Steps>
  <Step title="Set Up the Connection">
    On the **New Agent-to-Agent (A2A) Connection** page, provide the following fields.

    | Field                              | Description                                                                                                                                                                                                                                                                |
    | ---------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
    | **Display Name**                   | A label for the connection. Up to 255 characters.                                                                                                                                                                                                                          |
    | **Agent Endpoint Name**            | A system name for the A2A endpoint, for example `booking-agent-a2a`. Up to 255 characters.                                                                                                                                                                                 |
    | **Environment**                    | The deployment the connection binds to. Select an environment to follow its active deployment automatically, or leave the default to use the working copy.                                                                                                                 |
    | **Provider Verification Strength** | Controls how strictly the platform trusts the provider's identity assertions for session continuity and linking. **Weak** is the default. Choose **Strong** only for channels/providers whose identity assertions you trust for stronger continuity and linking decisions. |
    | **Initial Status**                 | **Active** connections can be used immediately. **Inactive** connections stay saved but disabled until you activate them.                                                                                                                                                  |

    Click **Create**.
