Path Item Object

Excerpt from the OpenAPI 3.1 specification about the Path Item object

Path Item Object

Describes the operations available on a single path. A Path Item MAY be empty, due to ACL constraints. The path itself is still exposed to the documentation viewer but they will not know which operations and parameters are available.

Fixed Fields
Field Name Type Description
$ref string Allows for a referenced definition of this path item. The referenced structure MUST be in the form of a Path Item Object. In case a Path Item Object field appears both in the defined object and the referenced object, the behavior is undefined. See the rules for resolving Relative References.
summary string An optional, string summary, intended to apply to all operations in this path.
description string An optional, string description, intended to apply to all operations in this path. CommonMark syntax MAY be used for rich text representation.
get Operation Object A definition of a GET operation on this path.
put Operation Object A definition of a PUT operation on this path.
post Operation Object A definition of a POST operation on this path.
delete Operation Object A definition of a DELETE operation on this path.
options Operation Object A definition of a OPTIONS operation on this path.
head Operation Object A definition of a HEAD operation on this path.
patch Operation Object A definition of a PATCH operation on this path.
trace Operation Object A definition of a TRACE operation on this path.
servers [Server Object] An alternative server array to service all operations in this path.
parameters [Parameter Object | Reference Object] A list of parameters that are applicable for all the operations described under this path. These parameters can be overridden at the operation level, but cannot be removed there. The list MUST NOT include duplicated parameters. A unique parameter is defined by a combination of a name and location. The list can use the Reference Object to link to parameters that are defined at the OpenAPI Object's components/parameters.

This object MAY be extended with Specification Extensions.
