Module slack_sdk.web.legacy_slack_response
A Python module for interacting and consuming responses from Slack.
Classes
class LegacySlackResponse (*, client, http_verb: str, api_url: str, req_args: dict, data: Union[dict, bytes], headers: dict, status_code: int, use_sync_aiohttp: bool = True)
-
An iterable container of response data.
Attributes
data
:dict
- The json-encoded content of the response. Along with the headers and status code information.
Methods
validate: Check if the response from Slack was successful. get: Retrieves any key from the response data. next: Retrieves the next portion of results, if 'next_cursor' is present.
Example:
import os import slack client = slack.WebClient(token=os.environ['SLACK_API_TOKEN']) response1 = client.auth_revoke(test='true') assert not response1['revoked'] response2 = client.auth_test() assert response2.get('ok', False) users = [] for page in client.users_list(limit=2): TODO: This example should specify when to break. users = users + page['members']
Note
Some responses return collections of information like channel and user lists. If they do it's likely that you'll only receive a portion of results. This object allows you to iterate over the response which makes subsequent API requests until your code hits 'break' or there are no more results to be found.
Any attributes or methods prefixed with _underscores are intended to be "private" internal use only. They may be changed or removed at anytime.

Methods
def get(self, key, default=None)
-
Retrieves any key from the response data.
Note
This is implemented so users can reference the SlackResponse object like a dictionary. e.g. response.get("ok", False)
Returns
The value from data or the specified default.
def validate(self)
-
Check if the response from Slack was successful.
Returns
(SlackResponse) This method returns it's own object. e.g. 'self'
Raises
SlackApiError
- The request to the Slack API failed.
