You can create a scheduled user message to send at a later time by passing ScheduledUserMessageCreateParams as an argument to the createScheduledUserMessage() method.
// Creates a scheduled user message after 5 minutes. val params = ScheduledUserMessageCreateParams( scheduledAt = System.currentTimeMillis() + TimeUnit.MINUTES.toMillis(5) ).apply { message = "Text message" translationTargetLanguages = listOf("en", "ko") data = null customType = null mentionType = MentionType.USERS mentionedUserIds = listOf(MENTIONED_USER_ID) metaArrays = null appleCriticalAlertOptions = null pushNotificationDeliveryOption = null } // The returned message is a pending message instance for the scheduled message. // It can be used in the same way as pending message from channel.sendUserMessage(). val pendingScheduledUserMessage = groupChannel.createScheduledUserMessage(params) { scheduledUserMessage, e -> if (e != null) { // Handle error. } // A user message has been successfully scheduled. // scheduledUserMessage.scheduledInfo will contain scheduled information. // scheduledUserMessage.sendingStatus will be SendingStatus.SCHEDULED. } You can also create a scheduled file message to send at a later time by passing ScheduledFileMessageCreateParams as an argument to the createScheduledFileMessage() method.
// Create a scheduled file message. val params = ScheduledFileMessageCreateParams( scheduledAt = System.currentTimeMillis() + TimeUnit.MINUTES.toMillis(5) ).apply { // Set `fileUrl` or `file` exclusively. fileUrl = FILE_URL file = FILE fileName = "Name of the file" mimeType = MIME_TYPE fileSize = FILE_SIZE thumbnailSizes = listOf(ThumbnailSize(THUMBNAIL_WIDTH, THUMBNAIL_HEIGHT)) data = null customType = null mentionType = MentionType.USERS mentionedUserIds = listOf(MENTIONED_USER_ID) metaArrays = null appleCriticalAlertOptions = null pushNotificationDeliveryOption = null } // The returned message is a pending message instance for the scheduled message. // It can be used in the same way as pending message from channel.sendFileMessage(). val pendingScheduledFileMessage = groupChannel.createScheduledFileMessage(params) { scheduledFileMessage, e -> if (e != null) { // Handle error. } // A file message has been successfully scheduled. // scheduledUserMessage.scheduledInfo will contain scheduled information. // scheduledUserMessage.sendingStatus will be SendingStatus.SCHEDULED. }
