# MsgSetCollectionApprovals

**Disclaimer:**\
This message is a streamlined alternative to [MsgUpdateCollection](/token-standard/messages/msg-update-collection.md). If you need to update many fields at once, we recommend using MsgUpdateCollection instead.

## MsgSetCollectionApprovals

Sets the collection approvals and update permissions for a collection. This is a convenience message that focuses specifically on collection approvals management.

### Overview

This message allows you to:

* Set collection approvals for the collection
* Configure permissions to update the collection approvals in the future

### Authorization & Permissions

Updates can only be performed by the **current manager** of the collection. The manager must have permission to update collection approvals according to the collection's current permission settings.

### Proto Definition

```protobuf
message MsgSetCollectionApprovals {
  option (cosmos.msg.v1.signer) = "creator";
  option (amino.name) = "tokenization/SetCollectionApprovals";

  // Address of the creator.
  string creator = 1;

  // ID of the collection.
  string collectionId = 2 [(gogoproto.customtype) = "Uint", (gogoproto.nullable) = false];

  // New collection approvals to set.
  repeated CollectionApproval collectionApprovals = 3;

  // Permission to update collection approvals
  repeated CollectionApprovalPermission canUpdateCollectionApprovals = 4;
}

message MsgSetCollectionApprovalsResponse {
  // ID of the collection.
  string collectionId = 1 [(gogoproto.customtype) = "Uint", (gogoproto.nullable) = false];
  // Details of each approval that was created, edited, or deleted.
  repeated ApprovalChange approvalChanges = 2;
  // Advisory review items about the transaction.
  repeated string reviewItems = 3;
}
```

### Response

The response includes:

* **`collectionId`**: The ID of the updated collection
* **`approvalChanges`**: A list of `ApprovalChange` entries describing each approval that was created, edited, or deleted (see [Approval Change Events](https://github.com/trevormil/bitbadges-docs/blob/master/x-tokenization/concepts/approval-change-events.md))
* **`reviewItems`**: Advisory strings about the transaction (see [Review Items](https://github.com/trevormil/bitbadges-docs/blob/master/x-tokenization/concepts/approval-change-events.md#review-items))

### Usage Example

```bash
# CLI command
bitbadgeschaind tx tokenization set-collection-approvals '[tx-json]' --from manager-key
```
