Create webhooks to receive Semgrep findings in your endpoints.
Semgrep AppSec Platform

import Notifications from "/src/components/concept/_notification-deduplication.mdx"

Enable webhooks

Webhooks are a generic method for Semgrep AppSec Platform to post JSON-formatted findings after each scan to your URL endpoint.

:::tip For Slack integrations

  • To integrate with Slack, use the Semgrep Slack integration. The webhook set up described in this guide does not apply to Slack integrations. :::

Semgrep sends two types of JSON objects:

semgrep_scan JSON object
A semgrep_scan object contains information about the CI job and other scan parameters, such as ignored files. Semgrep sends a single semgrep_scan object every time a scan is run. This includes diff-aware scans, full scans, and scans that have no findings.
semgrep_finding JSON object
A semgrep_finding object is a single record of a new finding. Semgrep sends new semgrep_finding objects based on how you have configured your notifications in Policies. See Set up webhooks to learn more.

Set up webhooks

Perform these steps in Semgrep AppSec Platform to set up webhooks:

  1. Create a webhook integration:
    1. On the navigation menu, click Settings > Integrations > Add.
    2. Click Webhook.
    3. In the Name field, enter a name for the integration.
    4. In the Webhook URL field, enter the target webhook URL for the integration.
    5. Click Subscribe.
  2. Turn notifications on:
    1. Click Rules > Policies > Rule Modes.
    2. Click the Edit button of the Rule Mode for which you want to receive webhook notifications. For example, if you want to be notified of all blocking findings through webhooks, click the Edit button of the Block mode.
    3. Repeat the previous step for all Rule Modes that you want to receive notifications for.

Test webhooks

To verify that Semgrep can post to your URL:

  1. Navigate to Settings > Integrations
  2. Click the Test button of the webhook integration you want to test.

The following screenshot displays an example request body of a webhook test: Successful webhook integration test
