OpenSRE’s Discord integration lets you trigger investigations with the /investigate slash command and receive findings as formatted embeds in a dedicated thread — all without leaving Discord.

​
Prerequisites

  • A Discord server where you can add applications (server Manage Server permission).
  • An OpenSRE host reachable from the public internet over HTTPS, so Discord can deliver interactions. For local development use a tunnel such as ngrok.

​
Step 1: Create a Discord application and bot

  1. Go to the Discord Developer Portal and click New Application.
  2. Give it a name (e.g. OpenSRE) and click Create.
  3. Open the Bot tab on the left sidebar. (New applications are created with a bot user automatically.)
    • Under Token, click Reset Token and copy the value. This is your Bot Token — treat it like a password.
    • Under Privileged Gateway Intents, no additional intents are required.
  4. Open the General Information tab and copy:
    • Application ID
    • Public Key

​
Step 2: Set bot permissions and invite to your server

  1. Open the OAuth2 → URL Generator tab.
  2. Under Scopes, select:
    • bot
    • applications.commands
  3. Under Bot Permissions, select:
    • Send Messages
    • Create Public Threads
    • Send Messages in Threads
    • Embed Links
    • Read Message History
  4. Copy the generated URL and open it in your browser.
  5. Select the server you want to add OpenSRE to and click Authorize.

​
Step 3: Set the interactions endpoint URL

Discord requires your server to verify it owns the endpoint before slash commands will work.
  1. In the General Information tab of your application, find Interactions Endpoint URL.
  2. Set it to: 
    https://<your-opensre-host>/discord/interactions
    Replace <your-opensre-host> with the public hostname where your OpenSRE server is running.
  3. Click Save Changes. Discord will immediately send a PING to that URL and expect a valid response — OpenSRE handles this automatically.
The /discord/interactions endpoint must be publicly reachable over HTTPS. If you are running locally, use a tunnel such as ngrok for testing.

​
Step 4: Configure the integration in OpenSRE

Run the setup wizard and select Discord: 
opensre onboard
When prompted, enter:
  • Bot Token — from Step 1
  • Application ID — from Step 1
  • Public Key — from Step 1
  • Default channel ID (optional) — the channel where findings are posted when an investigation is triggered from the CLI rather than from a slash command. To find a channel ID, right-click the channel in Discord → Copy Channel ID (requires Developer Mode in Discord settings).
OpenSRE then registers the /investigate slash command on your application by calling Discord’s API with the bot token and application ID. If the call fails (for example, because the token is wrong), you’ll see a warning in the wizard output but the integration will still be saved — re-run the wizard with corrected credentials to retry. The wizard writes the following environment variables to your .env file:
VariableDescription
DISCORD_BOT_TOKENBot token for API calls
DISCORD_APPLICATION_IDApplication ID for slash command registration
DISCORD_PUBLIC_KEYEd25519 public key for signature verification
DISCORD_DEFAULT_CHANNEL_IDFallback channel for CLI-triggered findings

​
Step 5: Trigger an investigation

In any Discord channel the bot has access to, run: 
/investigate alert:<alert text or JSON>
OpenSRE will:
  1. Acknowledge the command immediately (Discord’s “thinking…” state).
  2. Run the investigation in the background.
  3. Post the findings as a rich embed in the same channel.
  4. Create a thread on that message for follow-up context.

Troubleshooting

Slash command not appearing in Discord The /investigate command is registered globally and may take up to one hour to propagate. Re-running opensre onboard and selecting Discord will re-register the command. DISCORD_PUBLIC_KEY not configured error on your server Ensure DISCORD_PUBLIC_KEY is set in your environment before starting the OpenSRE server. Re-run opensre onboard to write it to .env. 
opensre onboard
Discord returns “This interaction failed” The background investigation task encountered an error, or your server did not respond to the followup within Discord’s 15-minute window. Check your OpenSRE server logs for details. 401 on the interactions endpoint Your server’s public key does not match the one Discord is signing with. Verify DISCORD_PUBLIC_KEY matches the value in the General Information tab of your Discord application.
