Freezing Channels

Freezing a channel prevents users from sending new messages and adding or deleting reactions.

Sending a message to a frozen channel returns an error message. Attempting to add or delete reactions returns a 403 Not Allowed error.

User roles with the UseFrozenChannel permission can still use frozen channels normally. By default, no user role has this permission.

Freeze a Channel

val channelClient = client.channel("messaging", "general")

channelClient.updatePartial(set = mapOf("frozen" to true)).enqueue { result ->
  if (result is Result.Success) {
    val channel = result.value
  } else {
    // Handle Result.Failure
  }
}

Unfreeze a Channel

val channelClient = client.channel("messaging", "general")

channelClient.updatePartial(set = mapOf("frozen" to false)).enqueue { result ->
  if (result is Result.Success) {
    val channel = result.value
  } else {
    // Handle Result.Failure
  }
}

Granting the Frozen Channel Permission

Permissions are typically managed in the Stream Dashboard under your app's Roles & Permissions settings. This is the recommended approach for most use cases.

To grant permissions programmatically, update the channel type using a server-side API call. See user permissions for more details.

// Backend SDK
var resp = chat.getChannelType("messaging").execute().getData();
var currentGrants = resp.getGrants();

List<String> adminGrants = new ArrayList<>(currentGrants.get("admin"));
adminGrants.add("use-frozen-channel");
currentGrants.put("admin", adminGrants);

chat.updateChannelType("messaging", UpdateChannelTypeRequest.builder()
    .grants(currentGrants)
    .automod(resp.getAutomod())
    .automodBehavior(resp.getAutomodBehavior())
    .maxMessageLength(resp.getMaxMessageLength())
    .build()).execute();
