Question 1

Simple Slack API vs Slack Java SDK which is better?

Accepted Answer

Simple Slack API excels at real-time WebSocket connections with minimal code, ideal for reactive bots. Slack's official Java SDK offers broader HTTP API coverage and is better for comprehensive integrations; choose based on real-time needs vs. feature completeness.

Question 2

How to handle Slack message reactions with Simple Slack API?

Accepted Answer

Since v0.5.0, the library supports reaction added and removed events. Add event listeners to the SlackSession to detect these events and respond programmatically, as demonstrated in the samples folder for custom bot logic.

Question 3

Can Simple Slack API send messages to private groups?

Accepted Answer

Yes, but the bot must be a member of the private group first. Use the invite or join commands from the library to add the bot, then send messages as with public channels, ensuring proper permissions.

Question 4

Simple Slack API WebSocket connection keeps failing

Accepted Answer

Verify your bot token has the required scopes (e.g., bot, channels:read) and that your network allows WebSocket connections. The library relies on Slack's RTM API, which may have rate limits or require stable internet access.

Question 5

How to add Simple Slack API to a Gradle project?

Accepted Answer

Use JitPack or Maven Central; for Gradle, add the dependency with group id com.ullink.slack and artifact id simpleslackapi. Check the README for version specifics and ensure you're using a supported Java version.

Question 6

Does Simple Slack API support Slack's new features like threads?

Accepted Answer

Not natively; you would need to use the postGenericSlackCommand method with appropriate parameters. The library's built-in commands are limited, so check the Slack API documentation for thread support and implement it manually.
