# Google Proximity Beacon API . beacons

## Instance Methods

Returns the attachments Resource.

Returns the diagnostics Resource.

Activates a beacon. A beacon that is active will return information and attachment data when queried via `beaconinfo.getforobserved`. Calling this method on an already active beacon will do nothing (but will return a successful response code). Authenticate using an [OAuth access token](https://developers.google.com/identity/protocols/OAuth2) from a signed-in user with **Is owner** or **Can edit** permissions in the Google Developers Console project.

Deactivates a beacon. Once deactivated, the API will not return information nor attachment data for the beacon when queried via `beaconinfo.getforobserved`. Calling this method on an already inactive beacon will do nothing (but will return a successful response code). Authenticate using an [OAuth access token](https://developers.google.com/identity/protocols/OAuth2) from a signed-in user with **Is owner** or **Can edit** permissions in the Google Developers Console project.

Decommissions the specified beacon in the service. This beacon will no longer be returned from `beaconinfo.getforobserved`. This operation is permanent -- you will not be able to re-register a beacon with this ID again. Authenticate using an [OAuth access token](https://developers.google.com/identity/protocols/OAuth2) from a signed-in user with **Is owner** or **Can edit** permissions in the Google Developers Console project.

Returns detailed information about the specified beacon. Authenticate using an [OAuth access token](https://developers.google.com/identity/protocols/OAuth2) from a signed-in user with **viewer**, **Is owner** or **Can edit** permissions in the Google Developers Console project. Requests may supply an Eddystone-EID beacon name in the form: `beacons/4!beaconId` where the `beaconId` is the base16 ephemeral ID broadcast by the beacon. The returned `Beacon` object will contain the beacon's stable Eddystone-UID. Clients not authorized to resolve the beacon's ephemeral Eddystone-EID broadcast will receive an error.

Searches the beacon registry for beacons that match the given search criteria. Only those beacons that the client has permission to list will be returned. Authenticate using an [OAuth access token](https://developers.google.com/identity/protocols/OAuth2) from a signed-in user with **viewer**, **Is owner** or **Can edit** permissions in the Google Developers Console project.

Retrieves the next page of results.

Registers a previously unregistered beacon given its `advertisedId`. These IDs are unique within the system. An ID can be registered only once. Authenticate using an [OAuth access token](https://developers.google.com/identity/protocols/OAuth2) from a signed-in user with **Is owner** or **Can edit** permissions in the Google Developers Console project.

Updates the information about the specified beacon. **Any field that you do not populate in the submitted beacon will be permanently erased**, so you should follow the "read, modify, write" pattern to avoid inadvertently destroying data. Changes to the beacon status via this method will be silently ignored. To update beacon status, use the separate methods on this API for activation, deactivation, and decommissioning. Authenticate using an [OAuth access token](https://developers.google.com/identity/protocols/OAuth2) from a signed-in user with **Is owner** or **Can edit** permissions in the Google Developers Console project.

### Method Details

`activate(beaconName, projectId=None, x__xgafv=None)`

    Activates a beacon. A beacon that is active will return information and attachment data when queried via `beaconinfo.getforobserved`.

        "ephemeralIdRegistration": { # Write-only registration parameters for beacons using Eddystone-EID format. Two ways of securely registering an Eddystone-EID beacon with the service are supported: 1. Perform an ECDH key exchange via this API, including a previous call to `GET /v1beta1/eidparams`. In this case the fields `beacon_ecdh_public_key` and `service_ecdh_public_key` should be populated and `beacon_identity_key` should not be populated. This method ensures that only the two parties in the ECDH key exchange can compute the identity key, which becomes a secret between them. 2. Derive or obtain the beacon's identity key via other secure means (perhaps an ECDH key exchange between the beacon and a mobile device or any other secure method), and then submit the resulting identity key to the service. In this case `beacon_identity_key` field should be populated, and neither of `beacon_ecdh_public_key` nor `service_ecdh_public_key` fields should be. The security of this method depends on how securely the parties involved (in particular the bluetooth client) handle the identity key, and obviously on how securely the identity key was generated. See [the Eddystone specification](https://github.com/google/eddystone/tree/master/eddystone-eid) at GitHub. # Write-only registration parameters for beacons using Eddystone-EID (remotely resolved ephemeral ID) format. This information will not be populated in API responses. When submitting this data, the `advertised_id` field must contain an ID of type Eddystone-UID. Any other ID type will result in an error.
          "rotationPeriodExponent": 42, # Indicates the nominal period between each rotation of the beacon's ephemeral ID. "Nominal" because the beacon should randomize the actual interval. See [the spec at github](https://github.com/google/eddystone/tree/master/eddystone-eid) for details. This value corresponds to a power-of-two scaler on the beacon's clock: when the scaler value is K, the beacon will begin broadcasting a new ephemeral ID on average every 2^K seconds.
          "initialClockValue": "A String", # The initial clock value of the beacon. The beacon's clock must have begun counting at this value immediately prior to transmitting this value to the resolving service. Significant delay in transmitting this value to the service risks registration or resolution failures. If a value is not provided, the default is zero.
          "beaconEcdhPublicKey": "A String", # The beacon's public key used for the Elliptic curve Diffie-Hellman key exchange. When this field is populated, `service_ecdh_public_key` must also be populated, and `beacon_identity_key` must not be.
          "initialEid": "A String", # An initial ephemeral ID calculated using the clock value submitted as `initial_clock_value`, and the secret key generated by the Diffie-Hellman key exchange using `service_ecdh_public_key` and `service_ecdh_public_key`.

        "advertisedId": { # Defines a unique identifier of a beacon as broadcast by the device. # The identifier of a beacon as advertised by it. This field must be populated when registering. It may be empty when updating a beacon record because it is ignored in updates. When registering a beacon that broadcasts Eddystone-EID, this field should contain a "stable" Eddystone-UID that identifies the beacon and links it to its attachments. The stable Eddystone-UID is only used for administering the beacon.
          "type": "A String", # Specifies the identifier type. Required.
          "id": "A String", # The actual beacon identifier, as broadcast by the beacon hardware. Must be [base64](http://tools.ietf.org/html/rfc4648#section-4) encoded in HTTP requests, and will be so encoded (with padding) in responses. The base64 encoding should be of the binary byte-stream and not any textual (such as hex) representation thereof. Required.
        },
        "beaconName": "A String", # Resource name of this beacon. A beacon name has the format "beacons/N!beaconId" where the beaconId is the base16 ID broadcast by the beacon and N is a code for the beacon's type. Possible values are `3` for Eddystone, `1` for iBeacon, or `5` for AltBeacon. This field must be left empty when registering. After reading a beacon, clients can use the name for future operations.
        "expectedStability": "A String", # Expected location stability. This is set when the beacon is registered or updated, not automatically detected in any way. Optional.
        "properties": { # Properties of the beacon device, for example battery type or firmware version. Optional.

        },
        "provisioningKey": "A String", # Some beacons may require a user to provide an authorization key before changing any of its configuration (e.g. broadcast frames, transmit power). This field provides a place to store and control access to that key. This field is populated in responses to `GET /v1beta1/beacons/3!beaconId` from users with write access to the given beacon. That is to say: If the user is authorized to write the beacon's confidential data in the service, the service considers them authorized to configure the beacon. Note that this key grants nothing on the service, only on the beacon itself.
      }

`list(pageSize=None, projectId=None, q=None, pageToken=None, x__xgafv=None)`

    Searches the beacon registry for beacons that match the given search criteria. Only those beacons that the client has permission to list will be returned. Authenticate using an [OAuth access token](https://developers.google.com/identity/protocols/OAuth2) from a signed-in user with **viewer**, **Is owner** or **Can edit** permissions in the Google Developers Console project.

    Args:
      pageSize: integer, The maximum number of records to return for this request, up to a server-defined upper limit.
      projectId: string, The project id to list beacons under. If not present then the project credential that made the request is used as the project. Optional.
      q: string, Filter query string that supports the following field filters: * `description:""` For example: `description:"Room 3"` Returns beacons whose description matches tokens in the string "Room 3" (not necessarily that exact string). The string must be double-quoted. * `status:` For example: `status:active` Returns beacons whose status matches the given value. Values must be one of the Beacon.Status enum values (case insensitive). Accepts multiple filters which will be combined with OR logic. * `stability:` For example: `stability:mobile` Returns beacons whose expected stability matches the given value. Values must be one of the Beacon.Stability enum values (case insensitive). Accepts multiple filters which will be combined with OR logic. * `place_id:""` For example: `place_id:"ChIJVSZzVR8FdkgRXGmmm6SslKw="` Returns beacons explicitly registered at the given place, expressed as a Place ID obtained from [Google Places API](/places/place-id). Does not match places inside the given place. Does not consider the beacon's actual location (which may be different from its registered place). Accepts multiple filters that will be combined with OR logic. The place ID must be double-quoted. * `registration_time[|=]` For example: `registration_time>=1433116800` Returns beacons whose registration time matches the given filter. Supports the operators: , =. Timestamp must be expressed as an integer number of seconds since midnight January 1, 1970 UTC. Accepts at most two filters that will be combined with AND logic, to support "between" semantics. If more than two are supplied, the latter ones are ignored. * `lat: lng: radius:` For example: `lat:51.1232343 lng:-1.093852 radius:1000` Returns beacons whose registered location is within the given circle. When any of these fields are given, all are required. Latitude and longitude must be decimal degrees between -90.0 and 90.0 and between -180.0 and 180.0 respectively. Radius must be an integer number of meters between 10 and 1,000,000 (1000 km). * `property:"="` For example: `property:"battery-type=CR2032"` Returns beacons which have a property of the given name and value. Supports multiple filters which will be combined with OR logic. The entire name=value string must be double-quoted as one string. * `attachment_type:""` For example: `attachment_type:"my-namespace/my-type"` Returns beacons having at least one attachment of the given namespaced type. Supports "any within this namespace" via the partial wildcard syntax: "my-namespace/*". Supports multiple filters which will be combined with OR logic. The string must be double-quoted. Multiple filters on the same field are combined with OR logic (except registration_time which is combined with AND logic). Multiple filters on different fields are combined with AND logic. Filters should be separated by spaces. As with any HTTP query string parameter, the whole filter expression must be URL-encoded. Example REST request: `GET /v1beta1/beacons?q=status:active%20lat:51.123%20lng:-1.095%20radius:1000`
      pageToken: string, A pagination token obtained from a previous request to list beacons.

Two ways of securely registering an Eddystone-EID beacon with the service are supported: 1. Perform an ECDH key exchange via this API, including a previous call to `GET /v1beta1/eidparams`. In this case the fields `beacon_ecdh_public_key` and `service_ecdh_public_key` should be populated and `beacon_identity_key` should not be populated. This method ensures that only the two parties in the ECDH key exchange can compute the identity key, which becomes a secret between them. 2.

In this case `beacon_identity_key` field should be populated, and neither of `beacon_ecdh_public_key` nor `service_ecdh_public_key` fields should be.

        "ephemeralIdRegistration": { # Write-only registration parameters for beacons using Eddystone-EID format. Two ways of securely registering an Eddystone-EID beacon with the service are supported: 1. Perform an ECDH key exchange via this API, including a previous call to `GET /v1beta1/eidparams`. In this case the fields `beacon_ecdh_public_key` and `service_ecdh_public_key` should be populated and `beacon_identity_key` should not be populated. This method ensures that only the two parties in the ECDH key exchange can compute the identity key, which becomes a secret between them. 2. Derive or obtain the beacon's identity key via other secure means (perhaps an ECDH key exchange between the beacon and a mobile device or any other secure method), and then submit the resulting identity key to the service. In this case `beacon_identity_key` field should be populated, and neither of `beacon_ecdh_public_key` nor `service_ecdh_public_key` fields should be. The security of this method depends on how securely the parties involved (in particular the bluetooth client) handle the identity key, and obviously on how securely the identity key was generated. See [the Eddystone specification](https://github.com/google/eddystone/tree/master/eddystone-eid) at GitHub. # Write-only registration parameters for beacons using Eddystone-EID (remotely resolved ephemeral ID) format. This information will not be populated in API responses. When submitting this data, the `advertised_id` field must contain an ID of type Eddystone-UID. Any other ID type will result in an error.
          "rotationPeriodExponent": 42, # Indicates the nominal period between each rotation of the beacon's ephemeral ID. "Nominal" because the beacon should randomize the actual interval. See [the spec at github](https://github.com/google/eddystone/tree/master/eddystone-eid) for details. This value corresponds to a power-of-two scaler on the beacon's clock: when the scaler value is K, the beacon will begin broadcasting a new ephemeral ID on average every 2^K seconds.
