# Cloud Interconnect API, gRPC: TrunkConnectionService.Update

Updates a TrunkConnection resource using the data specified in the request.
Method starts an asynchronous operation that can be cancelled while it is in progress.

## gRPC request

**rpc Update ([UpdateTrunkConnectionRequest](#yandex.cloud.cic.v1.UpdateTrunkConnectionRequest)) returns ([operation.Operation](#yandex.cloud.operation.Operation))**

## UpdateTrunkConnectionRequest {#yandex.cloud.cic.v1.UpdateTrunkConnectionRequest}

{
  "trunk_connection_id": "string",
  "update_mask": "google.protobuf.FieldMask",
  "name": "string",
  "description": "string",
  "labels": "map<string, string>",
  "deletion_protection": "bool"
}
```

#|
||Field | Description ||
|| trunk_connection_id | **string**

ID of the TrunkConnection resource to return.

The maximum string length in characters is 50. ||
|| update_mask | **[google.protobuf.FieldMask](https://developers.google.com/protocol-buffers/docs/reference/csharp/class/google/protobuf/well-known-types/field-mask)**

Field mask that specifies which fields of the TrunkConnection resource are going to be updated. ||
|| name | **string**

Name of the trunkConnection.
The name must be unique within the folder.
Value must match the regular expression ```\|[a-zA-Z]([-_a-zA-Z0-9]{0,61}[a-zA-Z0-9])?```.

The string length in characters for each key must be 1-63.
Each key must match the regular expression `[a-z][-_0-9a-z]*`.

The maximum string length in characters for each value is 63. The string length in characters for each key must be 1-63. Each key must match the regular expression ` [a-z][-_0-9a-z]* `. Each value must match the regular expression ` [-_0-9a-z]* `. No more than 64 per resource. ||

  "created_by": "string",
  "modified_at": "google.protobuf.Timestamp",

```

An Operation resource. For more information, see [Operation](../../../../api-design-guide/concepts/operation.md).

#|
||Field | Description ||
|| id | **string**

ID of the operation. ||
|| description | **string**

Description of the operation. 0-256 characters long. ||
|| created_at | **[google.protobuf.Timestamp](https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#timestamp)**

Creation timestamp. ||
|| created_by | **string**

ID of the user or service account who initiated the operation. ||
|| modified_at | **[google.protobuf.Timestamp](https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#timestamp)**

The time when the Operation resource was last modified. ||
|| done | **bool**

If the value is `false`, it means the operation is still in progress.
If `true`, the operation is completed, and either `error` or `response` is available. ||
|| metadata | **[google.protobuf.Any](https://developers.google.com/protocol-buffers/docs/proto3#any)**

Service-specific metadata associated with the operation.
It typically contains the ID of the target resource that the operation is performed on.
Any method that returns a long-running operation should document the metadata type, if any. ||
|| error | **[google.rpc.Status](https://cloud.google.com/tasks/docs/reference/rpc/google.rpc#status)**

The error result of the operation in case of failure or cancellation.

Includes only one of the fields `error`, `response`.

The operation result.
If `done == false` and there was no failure detected, neither `error` nor `response` is set.
If `done == false` and there was a failure detected, `error` is set.
If `done == true`, exactly one of `error` or `response` is set. ||
|| response | **[google.protobuf.Any](https://developers.google.com/protocol-buffers/docs/proto3#any)**

The normal response of the operation in case of success.
If the original method returns no data on success, such as Delete,
the response is [google.protobuf.Empty](https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#google.protobuf.Empty).
If the original method is the standard Create/Update,
the response should be the target resource of the operation.
Any method that returns a long-running operation should document the response type, if any.

Includes only one of the fields `error`, `response`.

The operation result.
If `done == false` and there was no failure detected, neither `error` nor `response` is set.
If `done == false` and there was a failure detected, `error` is set.
If `done == true`, exactly one of `error` or `response` is set. ||
