Stripe: Create a billing meter event

← Billing operations · Get started

Operation stripe.postbillingmeterevents

Provider route: POST /v1/billing/meter_events. Alter supplies the connection’s credentials and routing.

Call through Alter

Install @alter-ai/sdk @alter-ai/stripe with npm, or alter-sdk-stripe with pip. Supply your connected customer’s grant ID and the arguments described below.

import { App } from "@alter-ai/sdk";
import { StripeIntegration } from "@alter-ai/stripe";

async function execute(input: Parameters<StripeIntegration["billing"]["postBillingMeterEvents"]>[0]) {
  const app = new App({ apiKey: process.env.ALTER_API_KEY! });
  try {
    const provider = new StripeIntegration(app, { grantId: process.env.PROVIDER_GRANT_ID! });
    const call = await provider.billing.postBillingMeterEvents(input);
    const result = await call.wait();
    return result.bodyJson();
  } finally {
    await app.close();
  }
}

import os
from alter_sdk import App
from alter_sdk_stripe import StripeIntegration

async def execute(arguments):
    async with App(api_key=os.environ["ALTER_API_KEY"]) as app:
        provider = StripeIntegration(app, {"grant_id": os.environ["PROVIDER_GRANT_ID"]})
        call = await provider.billing.post_billing_meter_events(arguments)
        result = await call.wait()
        return result.body_json()

Input

Field	Type	Presence	Description and constraints
$	object	Root	Additional keys: not allowed
headers	object	Optional	Additional keys: not allowed
headers.Idempotency-Key	string	Optional	Minimum length: 1 Maximum length: 255
body	object	Required within parent	Additional keys: not allowed
body.event_name	string	Required within parent	The name of the meter event. Corresponds with the `event_name` field on a meter. Maximum length: 100
body.expand	array	Optional	Specifies which fields in the response should be expanded.
body.expand[]	string	Each item	Maximum length: 5000
body.identifier	string	Optional	A unique identifier for the event. If not provided, one is generated. We recommend using UUID-like identifiers. Stripe enforces uniqueness within a rolling period of at least 24 hours. The enforcement of uniqueness primarily addresses issues arising from accidental retries or other problems occurring within extremely brief time intervals. This approach helps prevent duplicate entries and ensures data integrity in high-frequency operations. Maximum length: 100
body.payload	object	Required within parent	The payload of the event. This must contain the fields corresponding to a meter’s `customer_mapping.event_payload_key` (default is `stripe_customer_id`) and `value_settings.event_payload_key` (default is `value`). Read more about the [payload](https://docs.stripe.com/billing/subscriptions/usage-based/meters/configure#meter-configuration-attributes). Additional keys: see wildcard field
body.payload.*	string	Additional keys
body.timestamp	integer	Optional	The time of the event. Measured in seconds since the Unix epoch. Must be within the past 35 calendar days or up to 5 minutes in the future. Defaults to current timestamp if not specified. Format: unix-time

Schemas

Create a billing meter event — response body

Field	Type	Presence	Description and constraints
$	object	Root	Meter events represent actions that customers take in your system. You can use meter events to bill a customer based on their usage. Meter events are associated with billing meters, which define both the contents of the event’s payload and how to aggregate those events.
created	JSON	Required within parent
created (anyOf 1)	integer	Alternative	Time at which the object was created. Measured in seconds since the Unix epoch. Format: unix-time
created (anyOf 2)	string	Alternative	Pattern: ^-?[0-9]+(?:\.[0-9]+)?(?:[eE][+-]?[0-9]+)?$
event_name	string	Required within parent	The name of the meter event. Corresponds with the `event_name` field on a meter. Maximum length: 100
identifier	string	Required within parent	A unique identifier for the event. Maximum length: 5000
livemode	boolean	Required within parent	If the object exists in live mode, the value is `true`. If the object exists in test mode, the value is `false`.
object	string	Required within parent	String representing the object's type. Objects of the same type share the same value. Known values: billing.meter_event
payload	object	Required within parent	The payload of the event. This contains the fields corresponding to a meter's `customer_mapping.event_payload_key` (default is `stripe_customer_id`) and `value_settings.event_payload_key` (default is `value`). Read more about the [payload](https://docs.stripe.com/billing/subscriptions/usage-based/meters/configure#meter-configuration-attributes). Additional keys: see wildcard field
payload.*	string	Additional keys	Maximum length: 100
timestamp	JSON	Required within parent
timestamp (anyOf 1)	integer	Alternative	The timestamp passed in when creating the event. Measured in seconds since the Unix epoch. Format: unix-time
timestamp (anyOf 2)	string	Alternative	Pattern: ^-?[0-9]+(?:\.[0-9]+)?(?:[eE][+-]?[0-9]+)?$

Policy, approvals and errors

SDK function policy ID: stripe.postbillingmeterevents. Catalog operation: PostBillingMeterEvents. Rules can name either ID; function rules distinguish managed calls and conservatively cover raw calls sharing the route. Existing grant permissions and policy rules apply. wait() returns an immediate result or waits for a required approval; it never approves the request itself. Persist the approval ID to resume after a restart.

Provider errors retain their response; JSON decoding raises ProviderAPIError for provider failures. ManagedOperationError identifies contract/input/retention errors. See error handling and provider-specific behavior. Sensitive input may be refused before approval storage. A decoding error never resubmits a write.
