The Go SDK's wait helpers can time out and miss requests that were captured when the client clock runs ahead of the server.
CaptureDuringcan also fail and delete its endpoint on one transient server error. Fix these before merging; the remaining findings are minor.

32-32: 🔒 Security & Privacy | 🔵 Trivial | ⚡ Quick winLimit the SSE line length.
ReadString('\n')has no size limit. A line with no terminating newline grows without bound in memory. The same applies tos.dataat Line 62, which grows for as long as the server sendsdata:lines without a blank line. Theidletimer does not help here. Any line or keepalive byte resets it.Read lines with a cap, for example 1 MiB. Return an error when a line exceeds the cap. The caller then reconnects or ends the stream.
♻️ Proposed fix
- line, err := s.reader.ReadString('\n') + line, err := s.readLine()Add this helper and constant to the file:
const maxSSELineBytes = 1 << 20 var errSSELineTooLong = errors.New("webhooks.cc: stream line too long") // readLine reads up to and including '\n', failing if the line exceeds maxSSELineBytes. func (s *sseReader) readLine() (string, error) { var buf []byte for { chunk, err := s.reader.ReadSlice('\n') buf = append(buf, chunk...) if len(buf) > maxSSELineBytes { return "", errSSELineTooLong } if err == bufio.ErrBufferFull { continue } return string(buf), err } }Add
"errors"to the imports. Apply a similar cap to the total size ofs.dataper event.Based on learnings: enforce a maximum line length when parsing SSE streams so an unterminated line cannot grow the read buffer without bound.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
CaptureDuring gives up on the first temporary poll error, unlike collect.
Any error from Requests.List makes CaptureDuring return at once, including a 502, a 503, a 429 or a network error. collect in requests.go treats the same errors as temporary and polls again. The WaitFor tests rely on that: "a server error does not end the wait". With the current code, one temporary 5xx in the middle of a capture fails the run. The temporary endpoint is then deleted, so the captured requests are lost.
Reuse collect so both wait paths handle errors the same way. Pass since from endpoint.CreatedAt, as CaptureEmailDuring does.

Not changing this here, for parity. captureDuring in the TypeScript and Python SDKs also returns on the first list error. Moving CaptureDuring onto the wait loop, with since taken from the endpoint's createdAt, is already on the list of changes to make in all SDKs together.

@kroqdotdev Understood. Keeping the current behavior for SDK parity is reasonable for this PR. The polling concern remains a deferred improvement, not a completed fix.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Retries can repeat non-idempotent POST calls such as Endpoints.Create.
When WithRetry is on, api retries every method after any network error or TimeoutError. It also retries every status in RetryOn, including 500, 502, 503 and 504. A timeout or a 5xx on POST /endpoints does not prove that the server did nothing. The server can create the endpoint before the response is lost, and the retry then creates a second endpoint. The caller never receives the first slug, so it cannot delete that endpoint. The orphan counts against the account and also leaks from WithTemporaryEndpoint and CaptureDuring.
Limit transport-error and 5xx retries to idempotent methods. A 429 is safe to retry for any method, because the server rejected the request before processing it.

Not changing this here, for parity. Retries are opt-in (MaxAttempts defaults to 1), and the TypeScript reference and the Python SDK retry every method in the same way. Limiting transport-error and 5xx retries to idempotent methods is a good change, but it should land in all three SDKs together, so I have added it to the cross-SDK follow-ups with the reasoning above.
There was a problem hiding this comment.
@kroqdotdev Understood. Deferring this to a coordinated change across all three SDKs is reasonable. The duplicate-operation risk remains when retries are enabled, but MaxAttempts: 1 avoids it by default.

From an independent review of #539: - A Standard Webhooks, Clerk, Resend or forwarding secret that decodes to no key ("whsec_", whitespace) is now an error. Before, an HMAC keyed with nothing verified, and anyone can compute one. Signing refuses it too, as WebCrypto does in the TypeScript SDK. - Headers in SendOptions replace built ones of the same name in any case, instead of adding a second content-type or signature header. - Subscribe's idle clock pauses while the loop body runs, so a slow consumer is not taken for a silent connection. - Waits overlap their polls by 30 seconds instead of 5: the receiver stamps receivedAt before the capture commits, and captures can queue per account. - JSON bodies write Go integers exactly (past 2^53 too) and float32 values with float32 digits; a value that contains itself fails instead of overflowing the stack. - whktest.Endpoint cuts the test name to the 100 characters endpoint names allow; Request.Slug carries the endpoint on search results; a response-rule condition always sends its value (eq "" needs it); Null on Name, ShowEmailExtracts or ForwardEnabled is refused before the API does. - Request, Endpoint, Usage and the email types marshal to the API's shape, so json.Marshal output reads back. - Missing conformance vectors fail only where WHK_CONFORMANCE_REQUIRED=1 (this repository's CI and release), not in a user's go test all. - The forwarding examples handle every error, not only *verify.Error.

…540) * fix(sdk-python): refuse secrets that decode to an empty key (0.1.2) decode_standard_webhook_secret turned "whsec_" or a whitespace-only secret into a zero-length HMAC key, and an HMAC keyed with nothing is one anyone can compute: verify_signature for standard-webhooks, clerk and resend, and the forwarding checks, accepted such forged signatures. It now raises ValueError, before any verdict, and request building refuses the key too, as WebCrypto does in the TypeScript SDK. A secret read from an empty variable or file is the realistic way to hit it. Found by an independent review of the Go port (#539), which has the same fix. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(sdk-python): an empty key is reported before the headers are checked From the review of #540: the tests always sent complete, fresh headers, so removing the early key check in the forwarding functions went unnoticed; missing headers or a stale timestamp would then have hidden the misconfigured secret behind missing_headers or timestamp_out_of_range. The new cases fail without the early check. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
The Go module webhooks.cc/go in packages/sdk-go, ported from the TypeScript SDK with the same scope as the Python one. Standard library only; context.Context and time.Duration throughout. - webhookscc: the client (endpoints, requests with WaitFor, WaitForAll, search, replay and a Subscribe stream to range over, emails with EmailQuery, ExtractCode and ExtractLink, forwarding secrets), SendTo and BuildRequest signing for 34 providers, matchers, CaptureDuring and CaptureEmailDuring. Errors match ErrUnauthorized, ErrNotFound, ErrRateLimited and ErrTimeout with errors.Is. Sends never follow redirects, whatever the caller's http.Client does. - verify: signature checks for 32 providers and for what webhooks.cc forwards, with no client or API key. PayPal certificates are fetched from the URL rebuilt from the checked parse, redirects followed by hand. - whktest: Client and Endpoint helpers for testing.TB. - Passes signing.json, verify.json, forwarding.json and matchers.json; Go takes time.Duration, so durations.json does not apply. The web app serves the go-import tag at /go?go-get=1 (and below it), with the subdirectory field Go 1.25 reads; a plain /go still redirects home. /docs/sdk/go, a Go track on the changelog, the install page and the docs nav. CI runs gofmt, vet, staticcheck and the race-enabled tests on Go 1.25 and stable, CodeQL analyses Go, and a tag packages/sdk-go/v* checks itself against Version and has the module proxy fetch it.

CodeQL on #539: X-RateLimit-Limit and -Remaining were parsed as 64-bit numbers and converted to int unchecked. Counts and Retry-After are now parsed as 32-bit numbers (anything larger reads as absent), and X-RateLimit-Reset stays 64-bit. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The review of the Python fix (#540) found that no test sent incomplete headers with an empty-key secret. The same test here showed that RelayedRequest checked its headers first, so a missing header hid the misconfigured secret behind missing_headers. It now derives the key first, like the other checks, and the test covers no headers and a stale timestamp for every forwarding function and Signature.
