Requests the creation of a new WebApp in the specified FirebaseProject. The result of this call is an Operation which can be used to track the provisioning process. The Operation is automatically deleted after completion, so there is no need to call DeleteOperation.


You will need authorization for at least one of the following scopes to make a valid call:


If unset, the scope for this method defaults to You can set the scope for this method like this: firebase1-beta1 --scope <scope> projects web-apps-create ...

Required Scalar Argument

  • <parent> (string)
    • The resource name of the parent FirebaseProject in which to create a WebApp, in the format: projects/PROJECT_IDENTIFIER/webApps Refer to the FirebaseProject name field for details about PROJECT_IDENTIFIER values.

Required Request Value

The request value is a data-structure with various fields. Each field may be a simple scalar or another data-structure. In the latter case it is advised to set the field-cursor to the data-structure's field to specify values more concisely.

For example, a structure like this:

  api-key-id: string
  app-id: string
  app-urls: [string]
  display-name: string
  name: string
  project-id: string
  web-id: string

can be set completely with the following arguments which are assumed to be executed in the given order. Note how the cursor position is adjusted to the respective structures, allowing simple field names to be used most of the time.

  • -r . api-key-id=sed
    • The key_id of the GCP ApiKey associated with this App. If set must have no restrictions, or only have restrictions that are valid for the associated Firebase App. Cannot be set in create requests, instead an existing valid API Key will be chosen, or if no valid API Keys exist, one will be provisioned for you. Cannot be set to an empty value in update requests.
  • app-id=et
    • Immutable. The globally unique, Firebase-assigned identifier for the WebApp. This identifier should be treated as an opaque token, as the data format is not specified.
  • app-urls=et
    • The URLs where the WebApp is hosted.
    • Each invocation of this argument appends the given value to the array.
  • display-name=vero
    • The user-assigned display name for the WebApp.
  • name=erat
    • The resource name of the WebApp, in the format: projects/PROJECT_IDENTIFIER /webApps/APP_ID * PROJECT_IDENTIFIER: the parent Project's ProjectNumber (recommended) or its ProjectId. Learn more about using project identifiers in Google's AIP 2510 standard. Note that the value for PROJECT_IDENTIFIER in any response body will be the ProjectId. * APP_ID: the globally unique, Firebase-assigned identifier for the App (see appId).
  • project-id=sed
    • Immutable. A user-assigned unique identifier of the parent FirebaseProject for the WebApp.
  • web-id=duo
    • Output only. Immutable. A unique, Firebase-assigned identifier for the WebApp. This identifier is only used to populate the namespace value for the WebApp. For most use cases, use appId to identify or reference the App. The webId value is only unique within a FirebaseProject and its associated Apps.

About Cursors

The cursor position is key to comfortably set complex nested structures. The following rules apply:

  • The cursor position is always set relative to the current one, unless the field name starts with the . character. Fields can be nested such as in -r f.s.o .
  • The cursor position is set relative to the top-level structure if it starts with ., e.g. -r .s.s
  • You can also set nested fields without setting the cursor explicitly. For example, to set a value relative to the current cursor position, you would specify -r struct.sub_struct=bar.
  • You can move the cursor one level up by using ... Each additional . moves it up one additional level. E.g. ... would go three levels up.

Optional Output Flags

The method's return value a JSON encoded structure, which will be written to standard output by default.

  • -o out
    • out specifies the destination to which to write the server's result to. It will be a JSON-encoded structure. The destination may be - to indicate standard output, or a filepath that is to contain the received bytes. If unset, it defaults to standard output.

Optional General Properties

The following properties can configure any call, and are not specific to this method.

  • -p $-xgafv=string

    • V1 error format.
  • -p access-token=string

    • OAuth access token.
  • -p alt=string

    • Data format for response.
  • -p callback=string

    • JSONP
  • -p fields=string

    • Selector specifying which fields to include in a partial response.
  • -p key=string

    • API key. Your API key identifies your project and provides you with API access, quota, and reports. Required unless you provide an OAuth 2.0 token.
  • -p oauth-token=string

    • OAuth 2.0 token for the current user.
  • -p pretty-print=boolean

    • Returns response with indentations and line breaks.
  • -p quota-user=string

    • Available to use for quota purposes for server-side applications. Can be any arbitrary string assigned to a user, but should not exceed 40 characters.
  • -p upload-type=string

    • Legacy upload protocol for media (e.g. "media", "multipart").
  • -p upload-protocol=string

    • Upload protocol for media (e.g. "raw", "multipart").
