Customer Endpoint

Sync customer profile data into Churn Buster so emails personalize correctly and segmentation has real signal.

1. Use the Churn Buster API customer endpoint to fetch customer data from Churn Buster, like the customer-specific card update link.

curl -X "GET" "https://api.churnbuster.io/v1/customers" \
     -H "Content-Type: application/json" \
     -u "ACCOUNT_ID:API_KEY" \
     -d $'{
  {
  "capture_url": "https://yoursite.com/billing?c="
}
}

We support finding customers by Churn Buster customer id, or source and source_id.

For example:

curl -X "GET" "https://api.churnbuster.io/v1/customers?id=10b0c034-0605-4ee0-8e08-4016febf63dc" \
    -H "Content-Type: application/json" \
    -u "ACCOUNT_ID:API_KEY"

or

curl -X "GET" "https://api.churnbuster.io/v1/customers?source=stripe&source_id=cus_EXAMPLE" \
     -H "Content-Type: application/json" \

2. Update customer information with the POST action below.

curl -X "POST" "https://api.churnbuster.io/v1/customers" \
     -H 'Content-Type: application/json' \
     -u 'ACCOUNT_UUID:API_KEY' \
     -d $'{
