Request body fields

Name	Type	Required	Description
`usage_timestamp`	Integer	Yes	The timestamp indicating when this usage occurred, represented as Epoch time in milliseconds.Example: `1738732394123` represents the timestamp for February 5, 2025, at 05:13:14.123 UTC. Note: The timestamp must be within the last 12 hours.
`properties`	Object	Yes	A schema-less field that accepts any JSON-formatted data to define the attributes of the ingested event. It is a requirement to structure the data in a flat format wherever possible for better compatibility with downstream processing. We strongly encourage using unique field names—particularly for fields intended for metering purposes. This approach enhances clarity and maintainability in the future. For example, a field named `status`, Can represent `string` values such as `accepted` or `processing` in one context. In another scenario, it might hold numeric values, such as HTTP response codes like `200`, `300`, or `400`. Note: There is a size limit of 1 KB. Learn more about field naming guidelines.
`deduplication_id`	String	Yes	An identifier used by the Chargebee's customer to distinguish between multiple events generated at the same timestamp for a single `subscription_id`. The combination of `usage_timestamp`, `subscription_id`, and `deduplication_id` uniquely identifies each event. Example: If 3 events are generated for `subscription_id` = `sub-1` at `2025-04-01T00:00:00.000Z`, each event must have a distinct `deduplication_id`.
`subscription_id`	String	Yes	The unique identifier of a subscription. Note: If an existing `subscription_id` is provided, usage data is recorded against it. If the subscription does not exist yet in Chargebee, a new `subscription_id` can be used, and the subscription can be imported later, once the usage is successfully recorded. During invoice generation, recorded usage linked to the `subscription_id` will be applied to the invoice.
