This page contains the following information:
- Timestamps: a 10 or 13 digit record of the time of the occurrence of certain action in a Sendbird application.
- Page tokens: opaque strings which are used to point a specific index in a data set for pagination.
- Languages supported for translation: the language code tables that Sendbird's message auto-translation and on-demand translation features currently support.
- Deprecated block modes: the block modes that are deprecated but still supported for customers who have been using since before.
Chat Platform API uses region-independent timestamps to record the time of when certain actions are performed in a Sendbird application. The timestamps take the form of Unix Time, mainly in milliseconds, which is a 13-digits number (for example, 1484012373521). A few resources, especially channels, contain timestamps in the form of seconds, which are 10-digits long. The length of the timestamp is specified in the parameter description in the API guide.
Note: Unix time may be checked on most Unix systems by typing
date +%son the command line.
When querying a set of data, the Chat API uses page tokens to return results in small and continuous chunks. A page token is simply an encoded location within a list, and can be passed as an argument to a parameter to begin a query from that location.
Like the following, calling a List query with the parameters returns 20 or less items starting from the location encoded in token=YXYWRFBTQlArEUBXWFNeF2p2FEFdUA~~.
A List query typically returns a next field in the response body. This field contains the next page token, which can be used to load the next chunk of results. If this field is blank, the query has reached the end of its results.
Note: If a page token is not specified, the query is started from the beginning of the data set.
Sendbird’s message auto-translation and on-demand features are powered by Google Cloud Translation API recognition engine. The following table shows the languages and codes that Google Cloud engine supports.
Note: Message translation through the Microsoft Translator engine is no longer available. All Sendbird applications that used the engine have been migrated and are now supported by Google Cloud Translation engine.

The following tables describe how the deprecated block modes work. They are only supported for customers who have been using it since before.
| Group channel | Messages | Push notification | Channel list |
|---|---|---|---|
1-on-1 | New messages from the blocked user will not be delivered to the channel, and an error for sending the message returned to a user. The blocked user is aware of their blocked status. | A user will not be notified that the blocked user sent a message. | A user's channel list will not be updated and rearranged from the blocked user's messages. |
1-on-N (group chat) | All the messages from blocked users are delivered to the channel. You can choose whether or not a user can view which users they have blocked in the UI of the channel. | Messages sent from blocked users will be notified to a user. | A user's channel list will be updated and rearranged from a blocked user's messages. |
| Group channel | Messages | Push notification | Channel list |
|---|---|---|---|
1-on-1 | New messages sent from the blocked user will not be delivered to the channel, but are saved and displayed to the blocked user's channel view. A blocked user is not aware of their blocked status. | A user will not be notified that the blocked user sent a message. | A user's channel list will not be updated and rearranged from the blocked user's messages. |
1-on-N (group chat) | All the messages sent from blocked users are delivered to the channel. A user can't see all messages that blocked users have sent so far. | Messages sent from blocked users will not be notified to a user. | A user's channel list will not be updated and rearranged from a blocked user's messages. |
