  • Arguments

    Required arguments

    Authentication token bearing required scopes. Tokens should be passed as an HTTP Authorization header or alternatively, as a POST parameter.

    Example
    xxxx-xxxxxxxxx-xxxx

    Conversation ID to fetch thread from.

    Example
    C1234567890

    Unique identifier of either a thread’s parent message or a message in the thread. ts must be the timestamp of an existing message with 0 or more replies. If there are no replies then just the single message referenced by ts will return - it is just an ordinary, unthreaded message.

    Example
    1234567890.123456
    Optional arguments

    Paginate through collections of data by setting the cursor parameter to a next_cursor attribute returned by a previous request's response_metadata. Default value fetches the first "page" of the collection. See pagination for more detail.

    Example
    dXNlcjpVMDYxTkZUVDI=

    Return all metadata associated with this message.

    Default
    0
    Example
    true

    Include messages with oldest or latest timestamps in results. Ignored unless either timestamp is specified.

    Default
    0
    Example
    true

    Only messages before this Unix timestamp will be included in results.

    Default
    now
    Example
    1234567890.123456

    The maximum number of items to return. Fewer than the requested number of items may be returned, even if the end of the users list hasn't been reached.

    Default
    1000
    Example
    20

    Only messages after this Unix timestamp will be included in results.

    Default
    0
    Example
    1234567890.123456

    Usage info

    This Conversations API method returns a cursor-paginated thread of messages posted to a conversation.

    The scopes and token types required to use this method vary by conversation type.

    Bot user tokens may use this method for direct message and multi-party direct message conversations but lack sufficient permissions to use this method on public and private channels.

    To use conversations.replies with public or private channel threads, use a user token with channels:history or groups:history scopes.

    The channel and ts arguments are always required. ts must be the timestamp of an existing message with 0 or more replies. If there are no replies then just the single message referenced by ts will return - it is just an ordinary message.

    Pagination

    This method uses cursor-based pagination to make it easier to incrementally collect information. To begin pagination, specify a limit value under 1000. We recommend no more than 200 results at a time.

    Responses will include a top-level response_metadata attribute containing a next_cursor value. 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.

    See pagination for more information.

    Pagination by time

    This form of pagination can be used in conjunction with cursors.

    The messages array contains up to 1000 messages between the oldest and latest timestamps. The earliest messages in the time range are returned first.

    If there were more than 1000 messages between oldest and latest, then has_more will be true in the response. In an additional call, set the ts value of the final message as latest to get the next page of messages.

    If a message has the same timestamp as oldest or latest it will not be included in the list. This functionality allows you to use the timestamps of specific messages as boundaries for the results. You can, however, have both timestamps be included in the time range by setting inclusive to true. The inclusive parameter is ignored when oldest or latest is not specified.
