Retrieve current usage
Current usage fetches real-time customer data for the open billing period.
Keep in mind that since this period isn’t closed yet, invoice details may evolve over time.
LAGO_URL="https://api.getlago.com"
API_KEY="__YOUR_API_KEY__"
EXTERNAL_CUSTOMER_ID="__EXTERNAL_CUSTOMER_ID__"
EXTERNAL_SUBSCRIPTION_ID="__EXTERNAL_SUBSCRIPTION_ID__"
curl --location --request GET "$LAGO_URL/api/v1/customers/$EXTERNAL_CUSTOMER_ID/current_usage?external_subscription_id=$EXTERNAL_SUBSCRIPTION_ID" \
--header "Authorization: Bearer $API_KEY" \
--header 'Content-Type: application/json'
Retrieve past usage
Retrieving historical customer usage data provides usage details for closed billing periods.
This data remains unchanged unless you’re in a grace period, where past usage can be adjusted for a draft invoice.

API_KEY="__YOUR_API_KEY__"

EXTERNAL_SUBSCRIPTION_ID="__EXTERNAL_SUBSCRIPTION_ID__"
