Slack Spring Boot

Find our documentation on https://slack-spring-boot.kreait.dev/

Create a Spring Boot Application

Create a new spring boot application for example on https://start.spring.io (best to use kotlin and gradle for this example)

Add the following to your build.gradle file

dependencies {
    implementation(group: "com.kreait.slack", name: "slack-spring-boot-starter", version: "{version}")
 }

Credentials

Locate your app credentials under the Basic Information menu item on https://api.slack.com/apps (select your app) By default there is 3 ways adding your slack credentials to the application

1. Create a file $HOME/.slack/credentials

   slack_app_client_id=<client_id>
   slack_app_client_secret=<client_secret>
   slack_app_signing_secret=<signing secret>

2. Set Environment Variables

   SLACK_APP_CLIENT_ID=<client_id>
   SLACK_APP_CLIENT_SECRET=<client_secret>
   SLACK_APP_SIGNING_SECRET=<signing secret>

3. Set JVM System Properties

   slack.application.client-id=<client_id>
   slack.application.client-secret=<client_secret>
   slack.application.signing=<signing secret>

If you want to provide your own CredentialsProvider implement the interface and expose it as a Bean/Component

Start your application

./gradlew bootRun
