Metronome Setup Catalog

End-to-end setup from pricing intent to a verified live contract. The catalog (Steps 1–4) is shared infrastructure created once; customers and contracts (Steps 5–6) repeat per customer. Base URL: https://api.metronome.com/v1 (prod) or https://staging.api.metronome.com/v1 (sandbox). Authenticate with Authorization: Bearer $METRONOME_API_TOKEN.

Scope: First-time catalog setup only. Does not cover Stripe Connect, Revenue Recognition, tax orchestration, or billing provider-specific features. For topics not covered here, say so explicitly — do not infer from general knowledge.

Routing

Read the relevant reference file before making any API calls.

Setup order

Hard dependencies — do not skip ahead. Save every ID returned at each step.

Step 1 → Billable Metric(s)      POST /v1/billable-metrics/create
Step 2 → Product(s)              POST /v1/contract-pricing/products/create
           ↑ needs BM IDs from Step 1
Step 3 → Rate Card               POST /v1/contract-pricing/rate-cards/create
Step 4 → Add rates               POST /v1/contract-pricing/rate-cards/addRates
           ↑ needs Product IDs from Step 2
Step 5 → Customer                POST /v1/customers
Step 6 → Contract                POST /v1/contracts/create
           ↑ needs customer_id from Step 5 + rate_card_id from Step 3
Step 7 → Verify                  GET /v1/customers/{id}/invoices (required)

Step 1 — Billable Metric(s)

Read <references/billable-metrics.md> to choose aggregation type and plan group keys.

POST /v1/billable-metrics/create
Authorization: Bearer $METRONOME_API_TOKEN
Content-Type: application/json

{
  "name": "<metric name>",
  "aggregation_type": "<SUM|COUNT|MAX|UNIQUE|LATEST>",
  "aggregation_key": "<property name>",
  "event_type_filter": { "in_values": ["<event_type>"] },
  "group_keys": [["<dimension>"]]
}

aggregation_key required for SUM, MAX, UNIQUE, LATEST. Not used for COUNT. Save: id → billable_metric_id

Step 2 — Product(s)

Read <references/products.md> to choose product type and configure group keys.

POST /v1/contract-pricing/products/create
Authorization: Bearer $METRONOME_API_TOKEN
Content-Type: application/json

{
  "name": "<product name>",
  "type": "USAGE",
  "billable_metric_id": "<billable_metric_id from Step 1>"
}

Save: id → product_id

Step 3 — Rate Card

POST /v1/contract-pricing/rate-cards/create
Authorization: Bearer $METRONOME_API_TOKEN
Content-Type: application/json

{ "name": "<rate card name>" }

Save: id → rate_card_id — needed for every contract you create.

Step 4 — Add rates

Read <references/rate-cards.md> for rate types, subscription rates, and tiered examples.

POST /v1/contract-pricing/rate-cards/addRates
Authorization: Bearer $METRONOME_API_TOKEN
Content-Type: application/json

{
  "rate_card_id": "<rate_card_id from Step 3>",
  "rates": [
    {
      "product_id": "<product_id from Step 2>",
      "rate_type": "FLAT",
      "price": <price in cents>,
      "starting_at": "<ISO8601>",
      "entitled": true
    }
  ]
}

entitled: true is required — omitting it leaves the product silent on contracts. All prices in cents: $0.01 → 1, $1.00 → 100, $10.00 → 1000.

Step 5 — Customer

POST /v1/customers
Authorization: Bearer $METRONOME_API_TOKEN
Content-Type: application/json

{
  "name": "<legal entity name>",
  "ingest_aliases": ["<your_system_customer_id>"]
}

ingest_aliases maps your internal customer ID to Metronome — use it as the customer_id field in usage events. Save: id → customer_id

For advanced customer setup (Salesforce ID, Slack channel, duplicate checking), use the metronome-create-customer skill.

Step 6 — Contract

POST /v1/contracts/create
Authorization: Bearer $METRONOME_API_TOKEN
Content-Type: application/json

{
  "customer_id": "<customer_id from Step 5>",
  "rate_card_id": "<rate_card_id from Step 3>",
  "starting_at": "<ISO8601>",
  "ending_before": "<ISO8601>"
}

ending_before is exclusive — a contract ending Dec 31 2026 = "2027-01-01T00:00:00Z". Omit ending_before for an evergreen (month-to-month) contract. Save: contract id

For contracts with prepaid commits, credits, rate overrides, or multi-year ramps, use the metronome-create-contract skill.

Step 7 — Verification (required)

Setup is not complete until the draft invoice is confirmed. Do not declare success without showing a line item.

Ingest a test event (bare JSON array — do not wrap in an object):

POST /v1/ingest
Authorization: Bearer $METRONOME_API_TOKEN
Content-Type: application/json

[{
  "transaction_id": "test-setup-verify-001",
  "customer_id": "<ingest_alias or customer_id>",
  "event_type": "<event_type from Step 1>",
  "timestamp": "<ISO8601 within contract period>",
  "properties": { "<aggregation_key>": 1 }
}]

Check the draft invoice:

GET /v1/customers/<customer_id>/invoices?type=USAGE&status=DRAFT
Authorization: Bearer $METRONOME_API_TOKEN

A line item with your product name and a non-zero quantity confirms the full chain is working. If no line item appears, check: event event_type matches the billable metric filter, timestamp falls within the contract period, and entitled: true was set on the rate.

Timing note: If the contract starting_at is in the future (> 24 hours from now), events with timestamps in that period will be rejected. In this case, verify the rate card structure directly instead:

POST /v1/contract-pricing/rate-cards/getRates
Authorization: Bearer $METRONOME_API_TOKEN
Content-Type: application/json

{ "rate_card_id": "<id>", "at": "<contract start ISO8601>" }

Confirm each product appears with a rate and entitled: true. Full invoice verification can be done once the contract period begins.

Critical rules

• Group keys are immutable after creation. Plan all pricing dimensions upfront — unused group keys are free, missing ones cannot be added retroactively.
• Rate cards are shared. Changing a rate propagates to all contracts without overrides. Never modify the rate card for one customer — use a contract-level override.
• All monetary amounts are in cents. $1 → 100, $0.01 → 1.
• entitled: true is required on each rate. Omitting it silently disables the product.
• Ingest body must be a bare JSON array. [{...}] not {"usage": [...]}.
• Confirm the environment before any write. If staging is unreachable, ask the user which environment to use — do not silently switch to production.
