All three integrations live under the project Integrations page. Each card shows status (Inactive or Active) and a Connect button. The Delivery Logs link in the top right shows every event Jakka has sent.
Connect Slack
Slack uses OAuth. Jakka requests the incoming-webhook scope, which is one-way only (Jakka can post to your Slack, but cannot read your Slack).
Click Connect Slack on the Integrations page.
Slack opens its standard workspace sign-in. Enter your workspace URL.
Authorize Jakka and pick the channel where messages should land.
You return to Jakka with the integration showing Active.
Connect Discord
Discord uses a manual webhook paste, not OAuth.
Open Discord and go to your server settings.
Navigate to Integrations > Webhooks.
Click New Webhook and configure it (channel, name).
Copy the webhook URL.
Back in Jakka, click Connect Discord, paste the URL into the Webhook URL field, and click Connect.
Connect Jira
Jira uses a three-step modal that captures your Atlassian Cloud credentials.
Click Connect Jira.
Step 1: enter your Jira Site URL (for example, yourcompany.atlassian.net).
Step 2: enter your email address and an API Token. Click Generate token to open Atlassian's token page if you do not have one. Your token is encrypted and stored securely.
Step 3: pick the default Jira project and issue type for Jakka-created tickets.
Test the connection
Once connected, send a test message from the integration card. Slack and Discord receive a sample notification; Jira creates a test ticket you can immediately close.
