Incrementing metered feature usage (event ingestion)

To increment usage for a user's subscribed metered feature, you can use the following API endpoint:

curl -X POST https://api.portcall.com/v1/usage/increment \
  -H "X-API-Key YOUR_SECRET_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "user_id": "USER_ID",
    "feature_id": "FEATURE_ID",
    "amount": 1
  }'

if the amount is not specified, it will default to incrementing by 1. You can use negative values to decrement usage as well.
