# Get Disposition Version

> Retrieve one published disposition version.

### Overview

<Note>
  Dispositions are enabled per organization. If your organization does not have access, these endpoints return `404`.
</Note>

Returns one immutable version created by [Publish Disposition](/api-v2/post/agents-id-dispositions-disposition-id-publish), including the exact definition that version executes. Find version ids with [List Disposition Versions](/api-v2/get/agents-id-dispositions-disposition-id-versions) or from `publishedVersionId` on [Get Disposition](/api-v2/get/agents-id-dispositions-disposition-id).

### Headers

<ParamField header="authorization" type="string" required>
  Your API key for authentication.
</ParamField>

### Path Parameters

<ParamField path="agent_id" type="string" required>
  The agent's unique identifier. Must be a UUID; otherwise returns `400` with the message `agentId must be a valid UUID`. Returns `404 Agent not found` if the agent is not in your organization.
</ParamField>

<ParamField path="disposition_id" type="string" required>
  The disposition's unique identifier. Must be a UUID; otherwise returns `400` with the message `dispositionId must be a valid UUID`. Returns `404 Disposition not found` if it does not belong to this agent.
</ParamField>

<ParamField path="version_id" type="string" required>
  The version's unique identifier. Must be a UUID; otherwise returns `400` with the message `versionId must be a valid UUID`. Returns `404 Disposition version not found` if it does not belong to this disposition.
</ParamField>
