Datadog Billing Setup - Costory Documentation

Terraform
Manual setup

Not supported.

Open Costory and go to Integrations > Datadog. The stepper guides you through each field.

Generate a Datadog API key and application key with the following permissions:
- usage_read (required): view usage and billing data
- billing_read (required): cost estimation
- ci_visibility_read (optional): CI metric visibility
- timeseries_query (optional): metric timeseries
Enter the API key and application key in the Costory stepper. Costory tests the connection and starts syncing.

On first sync, Costory backfills up to 12 months of historical usage data.

What Costory includes

Usage-based billing estimates across all Datadog products (infrastructure, APM, logs, etc.).
Per-product cost breakdown (group by Service name).
Historical usage data for trend analysis.

What Costory does not include

Committed-use or contract pricing. Costory ingests usage estimates, not final invoices.
Custom metrics pricing beyond what the Datadog usage API exposes.
