Modifies the PushConfig for a specified subscription. This may be used to change a push subscription to a pull one (signified by an empty PushConfig) or vice versa, or change the endpoint URL and other attributes of a push subscription. Messages will accumulate for delivery continuously through the call regardless of changes to the PushConfig.

Scopes

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

  • https://www.googleapis.com/auth/cloud-platform
  • https://www.googleapis.com/auth/pubsub

If unset, the scope for this method defaults to https://www.googleapis.com/auth/cloud-platform. You can set the scope for this method like this: pubsub1 --scope <scope> projects subscriptions-modify-push-config ...

Required Scalar Argument

  • <subscription> (string)
    • Required. The name of the subscription. Format is projects/{project}/subscriptions/{sub}.

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:

ModifyPushConfigRequest:
  push-config:
    attributes: { string: string }
    no-wrapper:
      write-metadata: boolean
    oidc-token:
      audience: string
      service-account-email: string
    push-endpoint: 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 .push-config attributes=key=dolores
    • Optional. Endpoint configuration attributes that can be used to control different aspects of the message delivery. The only currently supported attribute is x-goog-version, which you can use to change the format of the pushed message. This attribute indicates the version of the data expected by the endpoint. This controls the shape of the pushed message (i.e., its fields and metadata). If not present during the CreateSubscription call, it will default to the version of the Pub/Sub API used to make such call. If not present in a ModifyPushConfig call, its value will not be changed. GetSubscription calls will always return a valid version, even if the subscription was created without this attribute. The only supported values for the x-goog-version attribute are: * v1beta1: uses the push format defined in the v1beta1 Pub/Sub API. * v1 or v1beta2: uses the push format defined in the v1 Pub/Sub API. For example: attributes { &#34;x-goog-version&#34;: &#34;v1&#34; }
    • the value will be associated with the given key

  • no-wrapper write-metadata=true

    • Optional. When true, writes the Pub/Sub message metadata to x-goog-pubsub-: headers of the HTTP request. Writes the Pub/Sub message attributes to : headers of the HTTP request.

  • ..oidc-token audience=et

    • Optional. Audience to be used when generating OIDC token. The audience claim identifies the recipients that the JWT is intended for. The audience value is a single case-sensitive string. Having multiple values (array) for the audience field is not supported. More info about the OIDC JWT token audience here: https://tools.ietf.org/html/rfc7519#section-4.1.3 Note: if not specified, the Push endpoint URL will be used.

  • service-account-email=accusam

  • .. push-endpoint=voluptua.

    • Optional. A URL locating the endpoint to which messages should be pushed. For example, a Webhook endpoint might use https://example.com/push.

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").
