COUNT billable metric

Dashboard
API

Here is how you can create a count aggregation from the UI:

Access the “Billable metrics” section via the side menu;
Create a new billable metric;
Define a name, a code and an optional description;
Select “count” as the aggregation type;
Apply dimension groups if any; and
Click “Add billable metric”.

This billable metric is metered only, meaning it cannot be recurring, and the number of billing units resets to 0 at the end of each period.

    LAGO_URL="https://api.getlago.com"
    API_KEY="__YOUR_API_KEY__"

    curl --location --request POST "$LAGO_URL/api/v1/billable_metrics" \
    --header "Authorization: Bearer $API_KEY" \
    --header 'Content-Type: application/json' \
    --data-raw '{
        "billable_metric": {
        "name": "API Request",
        "code": "api_requests",
        "description": "Number of API requests.",
        "aggregation_type": "count_agg",
        "group": {}
    }
}'

Calculation example

Lago calculates the COUNT(events.code) for the two following events received.

//Event received #1
{
    "transaction_id": "transaction_1",
    "external_customer_id": "1",
    "timestamp": "2022-03-16T00:00:00Z",
    "code": "api_requests",
    "properties": {}
}

//Event received #2
{
    "transaction_id": "transaction_2",
    "external_customer_id": "1",
    "timestamp": "2022-03-17T00:00:00Z",
    "code": "api_requests",
    "properties": {}
}

In that case, with this aggregation type, Lago simply counts the number of events received, resulting in a billable value of 2 units.
