Why did Beeminder charge my card?
On your Payments page, you can see all the past charges we've made, from all sources: derailments, subscriptions, GTBee, IFTTT charge action, and the charge endpoint of the Beeminder API. This should have a description explaining what the charge is and where it came from.
Each charge is either paid, failed, settled (PayPal only), or refunded. One failed charge may be listed multiple times — once it's failed, it will never update to paid; a new charge with the same information is created and tried.
Note that derailment charges are usually listed for one day after you actually derailed on the goal, due to the 24-hour legitimacy check waiting period between the derailment happening and the charge being processed. This delay can be increased by support if necessary, so sometimes a charge will be listed a few days after the actual derailment happened.
You should be able to cross-check any charges on your card with our list to see exactly what triggered the charge. If anything seems off, please contact support and we can investigate!
