Failed Payments API Endpoint

When a recurring payment fails in your billing system, notify Churn Buster so that a recovery campaign can be started.

2-step setup

  1. Add a trigger in your in-house logic, or subscribe to a webhook from your payment processor or subscription management tool, when recurring payments fail. You won't need to make this API request for one-off payments.
  2. When that trigger occurs or the webhook is received, submit the following API request to Churn Buster.
curl -X "POST" "https://api.churnbuster.io/v1/failed_payments" \
    -H "Content-Type: application/json" \
    -u "ACCOUNT_ID:API_KEY" \
    -d $'{
 "payment": {
   "source": "in_house",
   "source_id": "ch_abc123",
   "amount_in_cents": 2900,
   "currency": "USD"
 },
 "customer": {
   "source": "in_house",
   "source_id": "cus_abc123",
   "email": "sarah@example.com",
   "properties": {
     "first_name": "Sarah",      
     "last_name": "Doe",
      "phone_number": "1111111111"
   }
 }
}

Important note about "source" and "source_id":

  • Wherever you see source in the API docs, set it to "in_house" or another consistent name that references your in-house subscription management system.
  • Wherever you see source_id in the API docs, set it to the ID from within your in-house system, with unique ID's for the Customer, Subscription, Payment Method, etc.
