Use [expand](#expansion) to include additional information about issues in the response. Note that, unlike the majority of instances where `expand` is specified, `expand` is defined as a list of values. The expand options are: * `renderedFields` Returns field values rendered in HTML format. * `names` Returns the display name of each field. * `schema` Returns the schema describing a field type. * `transitions` Returns all possible transitions for the issue. * `operations` Returns all possible operations for the issue. * `editmeta` Returns information about how each field can be edited. * `changelog` Returns a list of recent updates to an issue, sorted by date, starting from the most recent. * `versionedRepresentations` Instead of `fields`, returns `versionedRepresentations` a JSON array containing each version of a field's value, with the highest numbered item representing the most recent version.

A list of fields to return for each issue, use it to retrieve a subset of fields. This parameter accepts a comma-separated list. Expand options include: * `*all` Returns all fields. * `*navigable` Returns navigable fields. * Any issue field, prefixed with a minus to exclude. The default is `*navigable`. Examples: * `summary,comment` Returns the summary and comments fields only. * `-description` Returns all navigable (default) fields except description. * `*all,-comment` Returns all fields except comments. Multiple `fields` parameters can be included in a request. Note: All navigable fields are returned by default. This differs from [GET issue](#api-rest-api-3-issue-issueIdOrKey-get) where the default is all fields.

Reference fields by their key (rather than ID). The default is `false`.

A [JQL](https://confluence.atlassian.com/x/egORLQ) expression.

The maximum number of items to return per page.

A list of up to 5 issue properties to include in the results. This parameter accepts a comma-separated list.

The index of the first item to return in the page of results (page offset). The base index is `0`.

Determines how to validate the JQL query and treat the validation results. Supported values: * `strict` Returns a 400 response code if any errors are found, along with a list of all errors (and warnings). * `warn` Returns all errors as warnings. * `none` No validation is performed. * `true` *Deprecated* A legacy synonym for `strict`. * `false` *Deprecated* A legacy synonym for `warn`. The default is `strict`. Note: If the JQL is not correctly formed a 400 response code is returned, regardless of the `validateQuery` value.
