    Our REST APIs are defined in OpenAPI v3.x. You can view the schema at [github.com/PagerDuty/api-schema](https://github.com/PagerDuty/api-schema).


    Note that properties in some schemas have fields not shown by default such as `readOnly`, `format`, and `default`. Hover your cursor over the right column that looks like `optional+1` to see the full list of fields.
