14-19: Add validation for timestamp parsing.The
parseIntcall could returnNaNif the timestamp is malformed, leading to an Invalid Date.const createValidSignature = (id: string, timestamp: string, body: string) => { const webhook = new Webhook(mockSecret); + const timestampNum = parseInt(timestamp); + if (isNaN(timestampNum)) { + throw new Error(`Invalid timestamp: ${timestamp}`); + } // Create a signature using the Standard Webhooks library - return webhook.sign(id, new Date(parseInt(timestamp) * 1000), body); + return webhook.sign(id, new Date(timestampNum * 1000), body); };

Learning: In the Clerk JavaScript repository, contributors create intentionally empty changeset files (containing only the YAML delimiters) when a PR touches only non-published parts of the codebase (e.g., sandbox assets). This signals that no package release is required, so such changesets should not be flagged as missing content.

114-114: standardwebhooks dependency verified
- The latest published version on npm is 1.0.0.
- Specifying
"^1.0.0"correctly allows future minor and patch updates while preserving API stability.✅ Approved and ready to merge.
.changeset/chubby-tires-end.md (1)
1-5: LGTM!The changeset correctly marks this as a patch since it's an internal refactoring without API changes. The description clearly explains the change.
packages/backend/src/__tests__/webhooks.test.ts (1)
84-189: Excellent test coverage additions!The new tests comprehensively cover:
- Valid and invalid signature scenarios
- Multiple signatures in headers
- Backward compatibility without version prefixes
- Standard Webhooks specification compliance
- Realistic Clerk webhook payloads
This significantly improves the test suite's robustness.
packages/backend/src/webhooks.ts (1)
31-53: Header mapping implementation looks good.The function correctly maps Svix headers to Standard Webhooks format while maintaining backward compatibility.

❓ According to standardwebhooks (TIL), it's a good practice to verify the webhook timestamp, making sure it's within a reasonable timeframe to prevent replay attacks. Do you think we should implement this here as well, or add this in a follow-up PR? |

125-137: Verify the type casting approach aligns with security practices.The type casting on line 128 bypasses TypeScript's type safety. However, given the previous discussion about trusting the payload after signature verification from the webhook provider, this approach is reasonable.
The implementation correctly handles errors and provides descriptive error messages. The use of
standardwebhookslibrary ensures proper signature verification with constant-time comparison.

File: packages/nextjs/src/server/__tests__/getAuthDataFromRequest.test.ts:63-75
Timestamp: 2025-06-16T01:27:54.563Z
Learning: In packages/nextjs/src/server/data/getAuthDataFromRequest.ts, the tokenType behavior on mismatch is intentionally different between array and single acceptsToken values: when acceptsToken is an array and the token type doesn't match any in the array, tokenType returns null; when acceptsToken is a single value and the token type doesn't match, tokenType returns the requested single value. This design aligns with developer intent and provides a more ergonomic API for common use cases.

File: packages/clerk-js/src/core/modules/apiKeys/index.ts:84-97
Timestamp: 2025-06-10T17:35:08.986Z
Learning: In the APIKeys service methods (packages/clerk-js/src/core/modules/apiKeys/index.ts), error handling is intentionally delegated to the component level rather than being implemented within the service methods themselves. This architectural pattern allows calling components to handle errors according to their specific UI needs.

packages/backend/src/webhooks.ts (4)
3-3: Good choice of standardized library.The switch to
standardwebhookslibrary provides better standardization and security with constant-time signature comparison.
34-53: Well-implemented header mapping function.The
createStandardWebhookHeadersfunction properly maps Svix headers to Standard Webhooks format with appropriate trimming and null-checking.
96-115: Excellent header validation with detailed error reporting.The header validation logic properly trims whitespace and provides detailed error messages listing all missing headers. This is a significant improvement over the previous implementation.
56-56: Add explicit return type annotation.The function lacks an explicit return type annotation, which is a TypeScript best practice for public APIs.
-export async function verifyWebhook(request: Request, options: VerifyWebhookOptions = {}): Promise<WebhookEvent> { +export async function verifyWebhook(request: Request, options: VerifyWebhookOptions = {}): Promise<WebhookEvent> {Wait, the return type is already present. Let me check again... Yes, it's there on line 87. This is not an issue.
packages/backend/src/__tests__/webhooks.test.ts (11)
1-1: Proper integration with standardwebhooks library.The import of
Webhookfromstandardwebhooksaligns with the refactored implementation and enables proper signature generation for testing.
7-7: Mock secret format updated correctly.The mock secret now uses the
whsec_prefix with base64 encoding, which is the proper format expected by thestandardwebhookslibrary.
14-19: Excellent helper function for signature generation.The
createValidSignaturehelper function properly uses thestandardwebhookslibrary to generate valid signatures for testing, replacing the previous hardcoded approach.
30-30: Updated error messages reflect generic validation.The test expectations now use generic "Missing required webhook headers" messages instead of Svix-specific errors, which aligns with the refactored validation logic.
Also applies to: 42-42, 58-58
61-82: Main validation test updated with dynamic signatures.The core validation test now uses dynamically generated signatures instead of hardcoded ones, which is more robust and realistic.
84-103: Comprehensive test coverage for valid signatures.This test case specifically verifies that valid signatures are accepted, providing clear test isolation and coverage.
105-122: Good coverage of invalid signature rejection.The test properly verifies that invalid signatures are rejected with appropriate error messages.
124-144: Excellent test for multiple signature handling.This test verifies that the webhook verification accepts requests when at least one signature in a space-separated list is valid, which is important for the Standard Webhooks specification.
146-166: Good backward compatibility testing.The test ensures that signatures work regardless of version prefixes, maintaining compatibility with different signature formats.
168-189: Comprehensive Standard Webhooks compliance test.This test uses a realistic Clerk webhook payload and verifies compliance with the Standard Webhooks specification, including the explicit
signingSecretparameter.
191-219: Excellent edge case testing for whitespace handling.These tests verify the enhanced header validation that treats empty strings and whitespace-only values as missing headers. This addresses the previous review comment about whitespace handling.
