Amazon API Gateway REST API Reference


Changes information about the base path mapping resource.

HTTP Request

PATCH /domainnames/<domain_name>/basepathmappings/<base_path>

Request Body

  "patchOperations" : [ {
    "op" : "String",
    "path" : "String",
    "value" : "String",
    "from" : "String"
  } ]

Request Body Fields

The request accepts the following fields in JSON format.

  • patchOperations
  • A list of update operations to be applied to the specified resource and in the order specified in this list.

    • op
    • An update operation to be performed with this PATCH request. The valid value can be add, remove, replace or copy. Not all valid operations are supported for a given resource. Support of the operations depends on specific operational contexts. Attempts to apply an unsupported operation on a resource will return an error message.

    • path
    • The op operation's target, as identified by a JSON Pointer value that references a location within the targeted resource. For example, if the target resource has an updateable property of {"name":"value"}, the path for this property is /name. If the name property value is a JSON object (e.g., {"name": {"child/name": "child-value"}}), the path for the child/name property will be /name/child~1name. Any slash ("/") character appearing in path names must be escaped with "~1", as shown in the example above. Each op operation can have only one path associated with it.

    • value
    • The new target value of the update operation. It is applicable for the add or replace operation. When using AWS CLI to update a property of a JSON value, enclose the JSON object with a pair of single quotes in a Linux shell, e.g., '{"a": ...}'. In a Windows shell, see Using JSON for Parameters.

    • from
    • The copy update operation's source as identified by a JSON-Pointer value referencing the location within the targeted resource to copy the value from. For example, to promote a canary deployment, you copy the canary deployment ID to the affiliated deployment ID by calling a PATCH request on a Stage resource with "op":"copy", "from":"/canarySettings/deploymentId" and "path":"/deploymentId".




The following table shows the supported and unsupported op operations for updateable BasePathMapping properties of the specified path values.

path op:add op:replace op:remove op:copy
/basepath Not supported Supported Not supported Not supported
/restapiId Not supported Supported Not supported Not supported
/stage Not supported Supported Not supported Not supported

To specify an empty base path in the request URL, set the base_path path variable to '(none)'.

Example: Update the base path mapping of an API


The following example request updates the base path (TestApi) of a custom domain name ( to map to a different deployment stage (stage2 of an API (fugvjdxtri).
