Cookies
TryWebhook sets no cookies. Not for sessions, not for analytics, not for preferences — the site has no use for one. The only cookies you can pick up here belong to Google, and only from the ads that pay for the tool.
Cookies we set: none
There is no login, so no session cookie. No analytics, so no visitor identifier. No preferences to remember on our side, so nothing to persist. Nothing on this site sends aSet-Cookie header, and nothing reads document.cookie. You can verify both in your browser's developer tools in about ten seconds.
That includes the cookies most sites call "strictly necessary". We do not have any, because there is no state to keep between requests.
The one thing we do store on your device
A single localStorage entry called trywebhook.recent, holding up to eight webhook URLs you recently created along with their creation and expiry times. It is what stops you losing a URL by closing the tab.
It is not a cookie: it is never attached to a request, never sent to our server and never readable by another site. Clearing site data for this domain deletes it, and the tool works without it — you just have to keep your own note of the URL.
Cookies from advertising
Advertising is not currently switched on: no ad code is served, so none of the cookies below is being set yet. This section describes what happens once it is, and is kept here rather than added quietly later.
TryWebhook is free and is paid for by Google AdSense. Google is the only advertising partner and the only third party embedded anywhere on the site. When an ad loads, Google and its ad-technology partners may set cookies and read similar device identifiers to select ads, cap how often you see the same one, measure clicks, detect fraud and — where you have allowed it — personalise what is shown based on your prior browsing.
Those cookies are Google's, not ours: we cannot read them, and Google decides which ones exist. The current set is roughly this.
| Cookie | Set by | What it does | Typical life |
|---|---|---|---|
__gads, __gpi | trywebhook.com | Measures how often you have seen a given ad, and limits repeats. Set by Google’s ad script in this site’s own namespace. | Up to 13 months |
IDE, test_cookie | doubleclick.net | Ad selection, measurement and reporting. test_cookie only checks whether your browser accepts cookies at all. | 13 months / 15 minutes |
NID, AEC | google.com | Ad preferences, security and abuse prevention across Google services. | 6 months |
FCCDCF, FCNEC | trywebhook.com | Remembers your consent choice so the dialog is not shown on every visit. Set only where a consent dialog is required. | Up to 13 months |
Google's own list is authoritative and changes without notice:how Google uses cookies in advertisingandhow it handles data on partner sites.
Consent, where it is required
If you are in the EEA, the UK or Switzerland, a consent dialog appears before any non-essential cookie is set. It is a Google-certified consent management platform, presented under the IAB Transparency and Consent Framework, and your choice is remembered so you are not asked on every page.
Declining costs you nothing here. The site works identically, you still get the tool, and the ads become non-personalised — selected from context rather than from anything about you. You can reopen the dialog and change your answer at any time from the link in the site footer, which appears once the dialog is active in your region.
Outside those regions no dialog is shown, because none is required. The controls in the next section work everywhere regardless.
Turning them off
- Block third-party cookies in your browser. Every part of this site keeps working, including the inspector, the real-time updates and the signature verifier. Nothing here needs a cookie to function.
- Turn off ad personalisation atGoogle My Ad Center, which applies to Google ads wherever you see them, not just here.
- Opt out across many networks at once viaYour Online Choices in Europe orthe DAA opt-out in the US.
- Use an ad blocker. We would rather you did not, since ads are the only reason this is free, but nothing is gated on them and you will not be nagged.
Never in the inspector
No ad code runs on /inspect, the page that displays your captured requests. That is not a preference we could quietly change: that page ships a strict Content Security Policy which forbids loading script from any origin but our own, so third-party advertising code cannot execute there even by accident.
The reason is straightforward. That page renders bytes sent by whoever has your URL, and a page rendering untrusted input is the last place a third-party script belongs. Ads live on the content pages, and only there.
Do Not Track and Global Privacy Control
We run no tracking of our own, so there is nothing for either signal to switch off on our side — your DNT or GPC header changes nothing here because the behaviour it asks for is already the default. How Google treats those signals in its advertising products is documented in its own policies, linked above.
