Retrieve a message

You can retrieve a specific message in an open or group channel by creating and passing the MessageRetrievalParams object as an argument into the getMessage(params:completionHandler:) method.

Swift

// Create a MessageRetrievalParams object.
let params = MessageRetrievalParams()
params.messageId = MESSAGE_ID
params.channelType = CHANNEL_TYPE
params.channelURL = CHANNEL_URL

// Pass the params to the parameter of the `getMessage(params:completionHandler:)` method.
BaseMessage.getMessage(params: params) { (message, error) in
    guard error == nil else {
        // Handle error.
        return 
    }

    // The specified message is successfully retrieved.
}
