# Drata Webhooks Drata doesn't have webhook subscriptions. A webhook is a **step** inside a Drata workflow: **Settings → Workflows → Create Workflow → add a "Send webhook" step**. When the workflow's trigger fires (for example, evidence linked to a control), Drata sends a `POST` to the URL you entered, with the headers and properties you configured. This differs from most providers in three ways: 1. **There is no documented signature.** Drata's help center describes authentication "as custom headers" and nothing else. It mentions that Drata uses Svix to send webhooks, but it documents no `svix-*` headers and no `whsec_` signing secret, so don't build verification around them. 2. **You choose what's in the body.** You pick the control and trigger properties to include. Every body has the base properties `event_type`, `timestamp`, `organization_id` and `workspace`. 3. **You choose the headers.** Auth headers and extra context headers are set per step. ## When to Use This Skill - How do I receive Drata webhooks? - How do I verify Drata webhook signatures? (You can't. Send a shared secret in a custom header instead.) - How do I set up the "Send webhook" step in a Drata workflow? - What does a Drata webhook payload look like? (`event_type`, `timestamp`, `control_*` fields.) - How do I handle `CONTROL_EVIDENCE_LINKED` or `CONTROL_TEST_CHANGED_TO_FAIL`? - Why does my Drata webhook arrive more than once? (Failed steps are retried up to three times.) ## Verification (core): a shared secret custom header In the Send webhook step, add a custom header with a long random value: ``` X-Webhook-Secret: 3f9c0e...a long random hex value... ``` The header name is your choice. Check it in constant time before you parse the body: ```javascript const crypto = require('crypto'); // NOT a Drata signature. This is a secret YOU put in the step's custom headers. function verifyDrataSecret(headerValue) { const expected = process.env.DRATA_WEBHOOK_SECRET; if (!expected) throw new Error('DRATA_WEBHOOK_SECRET is not set'); // fail closed if (typeof headerValue !== 'string') return false; const a = Buffer.from(headerValue); const b = Buffer.from(expected); // Length check first: timingSafeEqual throws on a length mismatch. return a.length === b.length && crypto.timingSafeEqual(a, b); } // Express: verifyDrataSecret(req.get('X-Webhook-Secret')) ``` > **For complete handlers with tests**, see [examples/express/](examples/express/), [examples/nextjs/](examples/nextjs/), [examples/fastapi/](examples/fastapi/). Return `401` for a missing or wrong secret and `500` when the secret isn't configured, so the endpoint never accepts everything by accident. Read the body raw (`express.raw({ type: '*/*' })`) and parse JSON only after the check. See [references/verification.md](references/verification.md). ## Payload Drata documents the body as three groups of properties: - **Base (always):** `event_type`, `timestamp`, `organization_id`, `workspace` - **Control properties (the ones you select):** `control_name`, `control_code`, `control_id`, `control_owners`, `control_readiness`, `control_description`, `control_approval_status`, `control_approvers`, `control_mapped_requirements`, `control_mapped_tests`, `control_evidence`, `control_policies`, `control_notes`, `control_custom_fields`, `control_workspace_name`, `control_workspace_id` - **Trigger-specific:** e.g. `evidence_name` and `linked_by` for `CONTROL_EVIDENCE_LINKED`, `test_name` for `CONTROL_TEST_CHANGED_TO_FAIL` Dates are ISO strings, booleans are `true`/`false`, and arrays (owners, etc.) are JSON. Drata's help center doesn't show a full example body, so treat any field you didn't select as absent. ## Events (`event_type` values for control workflows) | `event_type` | Fires when | |---|---| | `CONTROL_DETAILS_UPDATED` | Control details are edited (`updated_by`) | | `CONTROL_READINESS_CHANGED_TO_NOT_READY` | A control becomes Not ready (`date_changed`) | | `CONTROL_READINESS_CHANGED_TO_READY` | A control becomes Ready (`date_changed`) | | `CONTROL_EVIDENCE_LINKED` / `CONTROL_EVIDENCE_UNLINKED` | Evidence is linked or unlinked | | `CONTROL_POLICY_LINKED` / `CONTROL_POLICY_UNLINKED` | A policy is linked or unlinked | | `CONTROL_TEST_MAPPED` / `CONTROL_TEST_UNMAPPED` | A test is mapped or unmapped | | `CONTROL_REQUIREMENT_MAPPED` / `CONTROL_REQUIREMENT_UNMAPPED` | A requirement is mapped or unmapped | | `CONTROL_TEST_CHANGED_TO_PASS` / `CONTROL_TEST_CHANGED_TO_FAIL` | A mapped test starts passing or failing | | `CONTROL_OWNER_UPDATED` | The control owner changes (`new_control_owner`, `old_control_owner`, `updated_by`) | | `CONTROL_MARKED_IN_SCOPE` / `CONTROL_MARKED_OUT_OF_SCOPE` | Scope changes (`changed_by`, `date_changed`) | Workflows for risks, evidence and personnel also support webhooks, but the pages this skill is based on only list `event_type` values for control workflows. Log unknown values and return `200`; a body with no `event_type` gets `400`. ## Delivery, Retries and Idempotency - Steps in a workflow run in parallel. If one fails, "Drata will automatically retry the failed step up to three times". Return a 2xx quickly. - There's no delivery ID header in Drata's documentation, so dedupe on body fields (this skill uses `event_type` + `control_id` + `timestamp`). - Drata doesn't document a timestamp tolerance. `timestamp` is the event time, not a signed value, so don't use it to reject requests. ## Environment Variables ```bash # REQUIRED. The value you put in the step's custom header. Generate with: openssl rand -hex 32 DRATA_WEBHOOK_SECRET= # OPTIONAL. The custom header name (case-insensitive). Default: X-Webhook-Secret DRATA_WEBHOOK_HEADER=X-Webhook-Secret ``` ## Local Development ```bash npx hookdeck-cli listen 3000 drata --path /webhooks/drata ``` No account required. The CLI creates a guest account on first run and gives you a public HTTPS URL to paste into the Send webhook step, plus a web UI for inspecting requests.
