<h2>Instance Methods</h2>
<p class="toc_element">
<code><a href="#acknowledge">acknowledge(subscription, body, x__xgafv=None)</a></code></p>
<p class="firstline">Acknowledges the messages associated with the `ack_ids` in the `AcknowledgeRequest`. The Pub/Sub system can remove the relevant messages from the subscription. Acknowledging a message whose ack deadline has expired may succeed, but such a message may be redelivered later. Acknowledging a message more than once will not result in an error.</p>
<p class="toc_element">
<code><a href="#create">create(name, body, x__xgafv=None)</a></code></p>
<p class="firstline">Creates a subscription to a given topic. If the subscription already exists, returns `ALREADY_EXISTS`. If the corresponding topic doesn't exist, returns `NOT_FOUND`. If the name is not provided in the request, the server will assign a random name for this subscription on the same project as the topic. Note that for REST API requests, you must specify a name.</p>
<p class="toc_element">
<code><a href="#delete">delete(subscription, x__xgafv=None)</a></code></p>
<p class="firstline">Deletes an existing subscription. All pending messages in the subscription are immediately dropped. Calls to `Pull` after deletion will return `NOT_FOUND`. After a subscription is deleted, a new one may be created with the same name, but the new one has no association with the old subscription, or its topic unless the same topic is specified.</p>
<p class="toc_element">
<code><a href="#get">get(subscription, x__xgafv=None)</a></code></p>
<p class="firstline">Gets the configuration details of a subscription.</p>
<p class="toc_element">
<code><a href="#getIamPolicy">getIamPolicy(resource, x__xgafv=None)</a></code></p>
<p class="firstline">Gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set.</p>
<p class="toc_element">
<code><a href="#list">list(project, pageSize=None, pageToken=None, x__xgafv=None)</a></code></p>
<p class="firstline">Lists matching subscriptions.</p>
<p class="toc_element">
<code><a href="#list_next">list_next(previous_request, previous_response)</a></code></p>
<p class="firstline">Retrieves the next page of results.</p>
<p class="toc_element">
<code><a href="#modifyAckDeadline">modifyAckDeadline(subscription, body, x__xgafv=None)</a></code></p>
<p class="firstline">Modifies the ack deadline for a specific message. This method is useful to indicate that more time is needed to process a message by the subscriber, or to make the message available for redelivery if the processing was interrupted. Note that this does not modify the subscription-level `ackDeadlineSeconds` used for subsequent messages.</p>
<p class="toc_element">
<code><a href="#modifyPushConfig">modifyPushConfig(subscription, body, x__xgafv=None)</a></code></p>
<p class="firstline">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`.</p>
<p class="toc_element">
<code><a href="#pull">pull(subscription, body, x__xgafv=None)</a></code></p>
<p class="firstline">Pulls messages from the server. Returns an empty list if there are no messages available in the backlog. The server may return `UNAVAILABLE` if there are too many concurrent pull requests pending for the given subscription.</p>
<p class="toc_element">
<code><a href="#setIamPolicy">setIamPolicy(resource, body, x__xgafv=None)</a></code></p>
<p class="firstline">Sets the access control policy on the specified resource. Replaces any existing policy.</p>
<p class="toc_element">
<code><a href="#testIamPermissions">testIamPermissions(resource, body, x__xgafv=None)</a></code></p>
<p class="firstline">Returns permissions that a caller has on the specified resource.</p>
<h3>Method Details</h3>
<div class="method">
<code class="details" id="acknowledge">acknowledge(subscription, body, x__xgafv=None)</code>
<pre>Acknowledges the messages associated with the `ack_ids` in the `AcknowledgeRequest`. The Pub/Sub system can remove the relevant messages from the subscription. Acknowledging a message whose ack deadline has expired may succeed, but such a message may be redelivered later. Acknowledging a message more than once will not result in an error.
Args:
subscription: string, The subscription whose message is being acknowledged. (required)
body: object, The request body. (required)
The object takes the form of:
{ # Request for the Acknowledge method.
"ackIds": [ # The acknowledgment ID for the messages being acknowledged that was returned by the Pub/Sub system in the `Pull` response. Must not be empty.
"A String",
],
}
x__xgafv: string, V1 error format.
Returns:
An object of the form:
{ # A generic empty message that you can re-use to avoid defining duplicated empty messages in your APIs. A typical example is to use it as the request or the response type of an API method. For instance: service Foo { rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty); } The JSON representation for `Empty` is empty JSON object `{}`.
}</pre>
</div>
<div class="method">
<code class="details" id="create">create(name, body, x__xgafv=None)</code>
<pre>Creates a subscription to a given topic. If the subscription already exists, returns `ALREADY_EXISTS`. If the corresponding topic doesn't exist, returns `NOT_FOUND`. If the name is not provided in the request, the server will assign a random name for this subscription on the same project as the topic. Note that for REST API requests, you must specify a name.
Args:
name: string, The name of the subscription. It must have the format `"projects/{project}/subscriptions/{subscription}"`. `{subscription}` must start with a letter, and contain only letters (`[A-Za-z]`), numbers (`[0-9]`), dashes (`-`), underscores (`_`), periods (`.`), tildes (`~`), plus (`+`) or percent signs (`%`). It must be between 3 and 255 characters in length, and it must not start with `"goog"`. (required)
body: object, The request body. (required)
The object takes the form of:
{ # A subscription resource.
"topic": "A String", # The name of the topic from which this subscription is receiving messages. The value of this field will be `_deleted-topic_` if the topic has been deleted.
"ackDeadlineSeconds": 42, # This value is the maximum time after a subscriber receives a message before the subscriber should acknowledge the message. After message delivery but before the ack deadline expires and before the message is acknowledged, it is an outstanding message and will not be delivered again during that time (on a best-effort basis). For pull subscriptions, this value is used as the initial value for the ack deadline. To override this value for a given message, call `ModifyAckDeadline` with the corresponding `ack_id` if using pull. The maximum custom deadline you can specify is 600 seconds (10 minutes). For push delivery, this value is also used to set the request timeout for the call to the push endpoint. If the subscriber never acknowledges the message, the Pub/Sub system will eventually redeliver the message. If this parameter is 0, a default value of 10 seconds is used.
"pushConfig": { # Configuration for a push delivery endpoint. # If push delivery is used with this subscription, this field is used to configure it. An empty `pushConfig` signifies that the subscriber will pull and ack messages using API methods.
"attributes": { # Endpoint configuration attributes. Every endpoint has a set of API supported attributes that can be used to control different aspects of the message delivery. The currently supported attribute is `x-goog-version`, which you can use to change the format of the push message. This attribute indicates the version of the data expected by the endpoint. This controls the shape of the envelope (i.e. its fields and metadata). The endpoint version is based on the version of the Pub/Sub API. If not present during the `CreateSubscription` call, it will default to the version of the API used to make such call. If not present during 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 possible values for this 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.

An object of the form:
{ # Defines an Identity and Access Management (IAM) policy. It is used to specify access control policies for Cloud Platform resources. A `Policy` consists of a list of `bindings`. A `Binding` binds a list of `members` to a `role`, where the members can be user accounts, Google groups, Google domains, and service accounts. A `role` is a named list of permissions defined by IAM. **Example** { "bindings": [ { "role": "roles/owner", "members": [ "user:mike@example.com", "group:admins@example.com", "domain:google.com", "serviceAccount:my-other-app@appspot.gserviceaccount.com", ] }, { "role": "roles/viewer", "members": ["user:sean@example.com"] } ] } For a description of IAM and its features, see the [IAM developer's guide](https://cloud.google.com/iam).

"members": [ # Specifies the identities requesting access for a Cloud Platform resource. `members` can have the following values: * `allUsers`: A special identifier that represents anyone who is on the internet; with or without a Google account. * `allAuthenticatedUsers`: A special identifier that represents anyone who is authenticated with a Google account or a service account. * `user:{emailid}`: An email address that represents a specific Google account. For example, `alice@gmail.com` or `joe@example.com`. * `serviceAccount:{emailid}`: An email address that represents a service account. For example, `my-other-app@appspot.gserviceaccount.com`. * `group:{emailid}`: An email address that represents a Google group.

<code class="details" id="list">list(project, pageSize=None, pageToken=None, x__xgafv=None)</code>
<pre>Lists matching subscriptions.
Args:
project: string, The name of the cloud project that subscriptions belong to. (required)
pageSize: integer, Maximum number of subscriptions to return.
pageToken: string, The value returned by the last `ListSubscriptionsResponse`; indicates that this is a continuation of a prior `ListSubscriptions` call, and that the system should return the next page of data.
x__xgafv: string, V1 error format.
Returns:
An object of the form:
{ # Response for the `ListSubscriptions` method.
"nextPageToken": "A String", # If not empty, indicates that there may be more subscriptions that match the request; this value should be passed in a new `ListSubscriptionsRequest` to get more subscriptions.
"subscriptions": [ # The subscriptions that match the request.
{ # A subscription resource.
"topic": "A String", # The name of the topic from which this subscription is receiving messages. The value of this field will be `_deleted-topic_` if the topic has been deleted.
"ackDeadlineSeconds": 42, # This value is the maximum time after a subscriber receives a message before the subscriber should acknowledge the message. After message delivery but before the ack deadline expires and before the message is acknowledged, it is an outstanding message and will not be delivered again during that time (on a best-effort basis). For pull subscriptions, this value is used as the initial value for the ack deadline. To override this value for a given message, call `ModifyAckDeadline` with the corresponding `ack_id` if using pull. The maximum custom deadline you can specify is 600 seconds (10 minutes). For push delivery, this value is also used to set the request timeout for the call to the push endpoint. If the subscriber never acknowledges the message, the Pub/Sub system will eventually redeliver the message. If this parameter is 0, a default value of 10 seconds is used.
"pushConfig": { # Configuration for a push delivery endpoint. # If push delivery is used with this subscription, this field is used to configure it. An empty `pushConfig` signifies that the subscriber will pull and ack messages using API methods.
"attributes": { # Endpoint configuration attributes. Every endpoint has a set of API supported attributes that can be used to control different aspects of the message delivery. The currently supported attribute is `x-goog-version`, which you can use to change the format of the push message. This attribute indicates the version of the data expected by the endpoint. This controls the shape of the envelope (i.e. its fields and metadata). The endpoint version is based on the version of the Pub/Sub API. If not present during the `CreateSubscription` call, it will default to the version of the API used to make such call. If not present during 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 possible values for this 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.
"a_key": "A String",
