# GetConnectorDefinitionVersion


Retrieves information about a connector definition version, including the connectors that the version contains. Connectors are prebuilt modules that interact with local infrastructure, device protocols, AWS, and other cloud services.

URI: `GET /greengrass/definition/connectors/ConnectorDefinitionId/versions/ConnectorDefinitionVersionId`

Produces: application/json

## CLI:


```
aws greengrass get-connector-definition-version \
  --connector-definition-id <value> \
  --connector-definition-version-id <value> \
  [--next-token <value>]  \
  [--cli-input-json <value>] \
  [--generate-cli-skeleton]
```

cli-input-json format:

```
{
"ConnectorDefinitionId": "string",
"ConnectorDefinitionVersionId": "string",
"NextToken": "string"
}
```

## Parameters:


[**ConnectorDefinitionId**](parameters-connectordefinitionidparam.md)  
The ID of the connector definition.  
where used: path; required: true  
type: string

[**ConnectorDefinitionVersionId**](parameters-connectordefinitionversionidparam.md)  
The ID of the connector definition version. This value maps to the `Version` property of the corresponding `VersionInformation` object, which is returned by `ListConnectorDefinitionVersions` requests. If the version is the last one that was associated with a connector definition, the value also maps to the `LatestVersion` property of the corresponding `DefinitionInformation` object.   
where used: path; required: true  
type: string

[**NextToken**](parameters-nexttokenparam.md)  
The token for the next set of results, or `null` if there are no more results.  
where used: query; required: false  
type: string
