The default SlackConfig enables the in-memory one. The default implementation of the datastore is in-memory one using the JVM heap memory. This allows the async client to accurately know the current traffic they generated toward the Slack Platform and estimate the remaining amount to call.
The good thing is that both sync and async clients maintain the metrics data in a MetricsDatastore together. The async client internally has its queue systems to avoid burst traffics as much as possible while MethodsClient, the synchronous client, always blindly sends requests. slack-api-client has a complete support for those tiers and AsyncMethodsClient, the async client, has great consideration for Rate Limits. There are several tiers to determine how frequently your apps can call Web APIs. The limits would be applied on a “per app per workspace” basis. Slack platform features and APIs rely on rate limits to help provide a predictably pleasant experience for users. class // the response class to bind the response body ) getenv ( "SLACK_TOKEN" ), // a bot token or user token AwesomeMethodResponse. add ( "user", "U1234567" ), // build a request body "thod", // the name of the API method System. postFormWithTokenAndParseResponse ( req -> req. getInstance () AwesomeMethodResponse response = slack. text ( "Write one, post anywhere" )) if ( response. Import .Message ChatPostMessageResponse response = slack. The concept behind Slack Web APIs is so straight-forward that it’s pretty easy to understand how given parameters will be sent in actual HTTP requests. To clearly understand what is happening here, take a look at a curl command example that is equivalent to the above Java code. If everything goes well, you will see a message like this in the #random channel in your workspace. build () // Get a response as a Java object ChatPostMessageResponse response = methods. text ( ":wave: Hi from a bot written in Java!" ). channel ( "#random" ) // Use a channel ID `C1234567` is preferrable. methods ( token ) // Build a request object ChatPostMessageRequest request = ChatPostMessageRequest. getenv ( "SLACK_TOKEN" ) // Initialize an API Methods client with the given token MethodsClient methods = slack.
Import .MethodsClient import. import. // Load an env variable // If the token is a bot token, it starts with `xoxb-` while if it's a user token, it starts with `xoxp-` String token = System. We highly recommend using env variables or other secure ways to store your tokens to avoid accidental exposures.
#Add gchat to slack client code#
NOTE: Hardcoding tokens in your source code is not preferable. The Slack App configuration pages help you get your first token for your development workspace. You get them from each workspace that an app has been installed. A token usually begins with xoxb- (bot token) or xoxp- (user token). To call a Web API method such as chat.postMessage, a MethodsClient instance needs to be initialized with a token. The most popular Slack Web API method is called chat.postMessage, and it’s used to send a message to a conversation.

Of course, it’s also supported! Check this guide for it. Here is the list of the methods in a Slack object to create an API client. Consult the section at the bottom of this page for details. For customizing the Slack API clients, initializing SlackConfig is also necessary.
You can access all supported API clients from the facade by following the fluent (in other words, method chaining) interface.
