# Messaging Service Versions

# Messaging Service Versions

Every change to a messaging service entity creates a new version. Use these endpoints to view the version history and retrieve specific versions.

## List Versions

<ParamField path="id" type="string" required>
  UUID of the messaging service.
</ParamField>

## Get Specific Version

Use `GET /v1/services/messagingServices/{id}/versions/{version}` to retrieve a specific version.

<ParamField path="id" type="string" required>
  UUID of the messaging service.
</ParamField>

<ParamField path="version" type="string" required>
  Version number to retrieve (e.g., `0.2`).
</ParamField>
