All messages have both a type and a sortable ts, but the other fields depend on the type. Messages of type "message" are user-entered text messages sent to the channel, while other types are events that happened within the channel. You can easily generate a URL for any specific message using chat.get. To retrieve a message from a thread, check out conversation.replies. GET /api/conversations.history?channel=C2EB2QT8A&latest=1476909142.000007&inclusive=true&limit=1Īuthorization: Bearer TOKEN_WITH_CHANNELS_HISTORY_SCOPE If it exists, you'll receive the queried message in return.įinally, use inclusive=true because otherwise we'll never retrieve the message we're actually after, just the ones that come after it. Provide another message's ts value as the latest parameter. If you know the ts of the message that is before or after of the specific message you're looking for set inclusive to false and use the oldest or latest value respectively. If you know the ts of a specific message: You'll need a message's ts value, uniquely identifying it within a conversation. Retrieving a single messageĬonversations.history can also be used to pluck a single message from the archive. The inclusive parameter is ignored when oldest or latest is not specified. You can, however, have both timestamps be included in the time range by setting inclusive to true. This functionality allows you to use the timestamps of specific messages as boundaries for the results. If a message has the same timestamp as oldest or latest it will not be included in the list. In an additional call, set the ts value of the final message as latest to get the next page of messages. If there were more than 100 messages between oldest and latest, then has_more will be true in the response. The most recent messages in the time range are returned first. The messages array contains up to 100 messages between the oldest and latest timestamps. This form of pagination can be used in conjunction with cursors.

By using this value as a cursor parameter in a subsequent request, along with limit, you may navigate through the collection page by virtual page. Responses will include a top-level response_metadata attribute containing a next_cursor value. We recommend no more than 200 results at a time. To begin pagination, specify a limit value under 1000. This method uses cursor-based pagination to make it easier to incrementally collect information.

The calling app must also have the relevant *:history scope for the conversation type.
