OpenAPI Specification

openapi: 3.2.0
info:
  title: Reference Subscription webhooks API
  description: 'Orb''s API is built with the following principles in mind:


    1. **Predictable developer experience**: Where applicable, the Orb API uses industry-standard patterns such as

    cursor-based pagination and standardized error output. To help with debugging in critical API

    actions, the API always strives to provide detailed and actionable error messages. Aliases

    such as external customer IDs aid in fast integration times.

    2. **Reliably real time**: Orb''s event-based APIs, such as event ingestion are designed to handle extremely high

    throughput and scale with concurrent load. Orb also provides a real-time event-level credits

    ledger and a highly performant webhooks architecture.

    3. **Flexibility at the forefront**: Features like timezone localization and the ability to amend historical usage

    show the flexible nature of the platform.
