conversations.replies

Retrieve a thread of messages posted to a conversation

This Conversations API method's required scopes depend on the type of channel-like object you're working with. To use the method, you'll need at least one of the channels:, groups:, im: or mpim: scopes corresponding to the conversation type you're working with.

This Conversations API method returns an entire thread (a message plus all the messages in reply to it), while conversations.history method returns only parent messages.

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.

Arguments

tokenRequired

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

Examplexxxx-xxxxxxxxx-xxxx

channelRequired

Conversation ID to fetch thread from.

ExampleC1234567890

tsRequired

Unique identifier of a thread's parent message. 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.

Example1234567890.123456

cursorOptional

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.

ExampledXNlcjpVMDYxTkZUVDI=

inclusiveOptional

Include messages with latest or oldest timestamp in results only when either timestamp is specified.

Default: 0

Exampletrue

latestOptional

End of time range of messages to include in results.

Default: now

Example1234567890.123456

limitOptional

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: 10

Example20

oldestOptional

Start of time range of messages to include in results.

Default: 0

Example1234567890.123456

Present arguments as parameters in application/x-www-form-urlencoded querystring or POST body. This method does not currently accept application/json.

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

You can also get messages of certain time range by specifying either or combination of both latest and oldest.

If a message has the same timestamp as latest or oldest it will not be included in the list. This allows a client to fetch all messages in a hole in channel history, by calling conversations.replies with latest set to the oldest message they have after the hole, and oldest to the latest message they have before the hole. However, you can cover the hole and include the exact moment of the specified timestamp, set inclusive to true. The inclusive is ignored when latest or oldest is not specified.

Errors

This table lists the expected errors that this method could return. However, other errors can be returned in the case where the service is down or other unexpected factors affect processing. Callers should always check the value of the ok params in the response.

`invalid_arg_name`	The method was passed an argument whose name falls outside the bounds of accepted or expected values. This includes very long names and names with non-alphanumeric characters other than `_`. If you get this error, it is typically an indication that you have made a very malformed API call.
`invalid_array_arg`	The method was passed an array as an argument. Please only input valid strings.
`invalid_charset`	The method was called via a `POST` request, but the `charset` specified in the `Content-Type` header was invalid. Valid charset names are: `utf-8` `iso-8859-1`.
`invalid_form_data`	The method was called via a `POST` request with `Content-Type` `application/x-www-form-urlencoded` or `multipart/form-data`, but the form data was either missing or syntactically invalid.

`internal_error`	The server could not complete your operation(s) without encountering an error, likely due to a transient issue on our end. It's possible some aspect of the operation succeeded before the error was raised.

Warnings

This table lists the expected warnings that this method will return. However, other warnings can be returned in the case where the service is experiencing unexpected trouble.

Warning	Description
`missing_charset`	The method was called via a `POST` request, and recommended practice for the specified `Content-Type` is to include a `charset` parameter. However, no `charset` was present. Specifically, non-form-data content types (e.g. `text/plain`) are the ones for which `charset` is recommended.
`superfluous_charset`	The method was called via a `POST` request, and the specified `Content-Type` is not defined to understand the `charset` parameter. However, `charset` was in fact present. Specifically, form-data content types (e.g. `multipart/form-data`) are the ones for which `charset` is superfluous.

Argument		Value
`token`	Required	Or, provide your own token:Need a token? Create and install a Slack app to begin.
`channel`	Required
`ts`	Required
`cursor`	Optional
`inclusive`	Optional, default=0
