Create an open channel

An open channel is ideal for use cases that require a small and static number of channels. To create an open channel on Sendbird Dashboard, follow the below steps:

1. In your dashboard, go to Chat > Open channels, and then click Create channel at the top-right corner.
2. In the dialog box that appears, specify the name, unique URL, cover image, and custom type of a channel.

You can also create a channel on demand or dynamically through the Chat SDK or the Chat API.

SBDOpenChannel::CreateChannel(NAME, CHANNEL_URL, COVER_URL, DATA, OPERATOR_USER_IDS, CUSTOM_TYPE, [](SBDOpenChannel* openChannel, SBDError* error) {
    if (error != nullptr) {
        // Handle error.
        return;
    }
});

Otherwise, you can create an open channel by passing a configured SBDOpenChannelParams object as an argument to the parameter in the CreateChannel() method like the following.

std::vector<std::wstring> operator_user_ids;
operator_user_ids.push_back(L"Tyler");

SBDOpenChannel::CreateChannel(SBDOpenChannelParams().SetOperatorUserIds(operator_user_ids), [](SBDOpenChannel* openChannel, SBDError* error) {
    if (error != nullptr) {
        // Handle error.
        return;
    }
});

Using the cover_url property and UpdateChannel() method, you can get and update the cover image URL of a channel.
