For instance, you can add the built-in RateLimitErrorRetryHandler this way: To use other retry handlers, you can pass a list of RetryHandler to the client constructor. The retry handler retries if an API client encounters a connectivity-related failure (e.g., Connection reset by peer). With the default settings, only ConnectionErrorRetryHandler with its default configuration (=only one retry in the manner of exponential backoff and jitter) is enabled. body = 'ok' # This is the simplest way to run the async method # but you can go with any ways to run it asyncio. send ( text = 'Hello!' ) assert response. Import asyncio # requires: pip install aiohttp from slack_client import AsyncWebhookClient url = '' async def send_message_via_webhook ( url : str ): webhook = AsyncWebhookClient ( url ) response = await webhook. So, to use this class, run pip install aiohttp beforehand. You use AsyncWebhookClient instead for it.ĪsyncWebhookClient internally relies on AIOHTTP library but it is an optional dependency. The webhook client is available in asynchronous programming using the standard asyncio library, too. send ( text = f 'You said ' '' ) # Acknowledge this request return make_response ( '', 200 ) return make_response ( '', 404 ) AsyncWebhookClient ¶ form webhook = WebhookClient ( response_url ) # Send a reply in the channel response = webhook. form = '/reply-this' : response_url = request.
