Add a collection

Adds a collection to an API. To do this, use the following `operationType` values: - `COPY_COLLECTION` — Copies a collection from the workspace and adds it to an API. - `CREATE_NEW` — Creates a new collection by providing the new collection's content. - `GENERATE_FROM_SCHEMA` — Generates the collection from an API schema. - `options` — An object that contains advanced creation options and their values. You can find a complete list of properties and their values in Postman's [OpenAPI to Postman Collection Converter OPTIONS documentation](https://github.com/postmanlabs/openapi-to-postman/blob/develop/OPTIONS.md). These properties are case-sensitive.
