What Webhook Jar does

Webhook Jar gives you inboxes that catch HTTP requests sent to their post URL, shows you what arrived, and checks it. Anyone who knows an inbox's view link can read it, so treat that link as a secret.

Plans and limits

• Without an account: an inbox lasts 48 hours and takes up to 500 requests.
• Free: 3 kept inboxes, 7 days of history on each, 5,000 requests a day across them.
• Solo, $9 a month: 25 kept inboxes, 90 days of history on each, 50,000 requests a day.

Requests older than your plan's history are deleted. Over the daily allowance, an inbox answers 429 until 00:00 UTC.

Paying, cancelling and refunds

Solo is charged monthly in advance by card through Stripe. Card charges appear as DEVELOPERDATA.NET. Billing questions: https://developerdata.net/support?tab=charge.

Cancel any time from Account and billing. You keep Solo until the end of the month you paid for, then move to Free: your 3 busiest inboxes stay kept, the others get 48 hours, and history past 7 days is deleted. Part months are not refunded. When the mistake is ours, we refund: the rules and the form are on Refunds.

A purchase may be credited to the partner who referred you, through our partner program. It never changes the price you pay.

Using it fairly

• Do not use an inbox to host or pass on malware, phishing pages, stolen data or anything unlawful.
• Do not send requests meant to overload the service, or try to read inboxes that are not yours.
• Do not send live secrets you are not allowed to share. We mask the ones we recognise, but you should rotate any you send.

We may close an inbox or an account that breaks these rules, straight away and without notice.

No guarantee

Webhook Jar is a testing and debugging tool, provided as it is. We work to keep it available and your data safe, but we do not promise it never fails or loses a request. Do not rely on it as the only copy of anything. To the extent the law allows, our liability is limited to what you paid us in the last 12 months.

Changes

We may change these terms. If a change matters to members, we say so by email before it takes effect.
