+  <code><a href="#batchDelete">batchDelete(beaconName, namespacedType=None, x__xgafv=None)</a></code></p>
+<p class="firstline">Deletes multiple attachments on a given beacon. This operation is permanent and cannot be undone. You can optionally specify `namespacedType` to choose which attachments should be deleted. If you do not specify `namespacedType`, all your attachments on the given beacon will be deleted. You also may explicitly specify `*/*` to delete all.</p>

+  <code><a href="#delete">delete(attachmentName, x__xgafv=None)</a></code></p>
+<p class="firstline">Deletes the specified attachment for the given beacon. Each attachment has a unique attachment name (`attachmentName`) which is returned when you fetch the attachment data via this API. You specify this with the delete request to control which attachment is removed. This operation cannot be undone.</p>
+<p class="toc_element">
+  <code><a href="#list">list(beaconName, namespacedType=None, x__xgafv=None)</a></code></p>
+<p class="firstline">Returns the attachments for the specified beacon that match the specified namespaced-type pattern. To control which namespaced types are returned, you add the `namespacedType` query parameter to the request. You must either use `*/*`, to return all attachments, or the namespace must be one of the ones returned from the `namespaces` endpoint.</p>
+<h3>Method Details</h3>
+<div class="method">
+    <code class="details" id="batchDelete">batchDelete(beaconName, namespacedType=None, x__xgafv=None)</code>
+  <pre>Deletes multiple attachments on a given beacon. This operation is permanent and cannot be undone. You can optionally specify `namespacedType` to choose which attachments should be deleted. If you do not specify `namespacedType`, all your attachments on the given beacon will be deleted. You also may explicitly specify `*/*` to delete all.
+
+Args:
+  beaconName: string, The beacon whose attachments are to be deleted. Required. (required)
+  namespacedType: string, Specifies the namespace and type of attachments to delete in `namespace/type` format. Accepts `*/*` to specify "all types in all namespaces". Optional.
+  x__xgafv: string, V1 error format.
+
+Returns:
+  An object of the form:
+
+    { # Response for a request to delete attachments.
+    "numDeleted": 42, # The number of attachments that were deleted.
+  }</pre>
+</div>
+
+<div class="method">
+    <code class="details" id="create">create(beaconName, body, x__xgafv=None)</code>
+  <pre>Associates the given data with the specified beacon. Attachment data must contain two parts:  
+- A namespaced type. 
+- The actual attachment data itself.  The namespaced type consists of two parts, the namespace and the type. The namespace must be one of the values returned by the `namespaces` endpoint, while the type can be a string of any characters except for the forward slash (`/`) up to 100 characters in length. Attachment data can be up to 1024 bytes long.
+
+Args:
+  beaconName: string, The beacon on which the attachment should be created. Required. (required)
+  body: object, The request body. (required)
+    The object takes the form of:
+
+{ # Project-specific data associated with a beacon.
+    "data": "A String", # An opaque data container for client-provided data. Must be [base64](http://tools.ietf.org/html/rfc4648#section-4) encoded in HTTP requests, and will be so encoded (with padding) in responses. Required.
+    "attachmentName": "A String", # Resource name of this attachment. Attachment names have the format: beacons/beacon_id/attachments/attachment_id. Leave this empty on creation.
+    "namespacedType": "A String", # Specifies what kind of attachment this is. Tells a client how to interpret the `data` field. Format is namespace/type. Namespace provides type separation between clients. Type describes the type of `data`, for use by the client when parsing the `data` field. Required.
+  }
+
+  x__xgafv: string, V1 error format.
+
+Returns:
+  An object of the form:
+
+    { # Project-specific data associated with a beacon.
+      "data": "A String", # An opaque data container for client-provided data. Must be [base64](http://tools.ietf.org/html/rfc4648#section-4) encoded in HTTP requests, and will be so encoded (with padding) in responses. Required.
+      "attachmentName": "A String", # Resource name of this attachment. Attachment names have the format: beacons/beacon_id/attachments/attachment_id. Leave this empty on creation.
+      "namespacedType": "A String", # Specifies what kind of attachment this is. Tells a client how to interpret the `data` field. Format is namespace/type. Namespace provides type separation between clients. Type describes the type of `data`, for use by the client when parsing the `data` field. Required.

+</div>
+
+<div class="method">
+    <code class="details" id="delete">delete(attachmentName, x__xgafv=None)</code>
+  <pre>Deletes the specified attachment for the given beacon. Each attachment has a unique attachment name (`attachmentName`) which is returned when you fetch the attachment data via this API. You specify this with the delete request to control which attachment is removed. This operation cannot be undone.
+
+Args:
+  attachmentName: string, The attachment name (`attachmentName`) of the attachment to remove. For example: `beacons/3!893737abc9/attachments/c5e937-af0-494-959-ec49d12738` Required. (required)
+  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 `{}`.

+
+<div class="method">
+    <code class="details" id="list">list(beaconName, namespacedType=None, x__xgafv=None)</code>

To control which namespaced types are returned, you add the `namespacedType` query parameter to the request. You must either use `*/*`, to return all attachments, or the namespace must be one of the ones returned from the `namespaces` endpoint.
+
+Args:
+  beaconName: string, The beacon whose attachments are to be fetched. Required. (required)
+  namespacedType: string, Specifies the namespace and type of attachment to include in response in namespace/type format. Accepts `*/*` to specify "all types in all namespaces".
+  x__xgafv: string, V1 error format.
+
+Returns:
+  An object of the form:
