openapi: 3.0.3 info: title: Device Data Volume Subscriptions description: | This API enables customers to subscribe to events related to data volume usage thresholds on a device. It supports both request and subscription modes to track remaining data volume. # Introduction ## Device Data Volume Subscriptions API consumers can receive notifications regarding data volume usage thresholds, such as when the remaining data volume reaches 50%, 75%, or 90% of the user's allocated data plan. This is useful for managing data usage and avoiding overage fees. # Relevant terms and definitions * **Device**: A device refers to any physical entity capable of network communication, identified via an IP address, phone number, or Network Access Identifier. # API Functionality The API exposes the following capabilities: ## Device Data Volume Subscriptions These endpoints allow management of subscriptions to data volume usage events. The CAMARA subscription model follows the CloudEvents specification. When subscribing, it is mandatory to provide the event `types` related to data volume thresholds you wish to track. The following event `types` are managed for this API: - `org.camaraproject.device-data-volume-subscriptions.v0.data-50-percent`: Event triggered when 50% of the data plan is consumed. - `org.camaraproject.device-data-volume-subscriptions.v0.data-75-percent`: Event triggered when 75% of the data plan is consumed. - `org.camaraproject.device-data-volume-subscriptions.v0.data-90-percent`: Event triggered when 90% of the data plan is consumed. - `org.camaraproject.device-data-volume-subscriptions.v0.data-exceeded`: Event triggered when the data plan is exceeded. Note: Additionally, the following events could be send, which do not require a dedicated subscription: - `org.camaraproject.device-data-volume-subscriptions.v0.subscription-started` is sent when the subscription starts. - `org.camaraproject.device-data-volume-subscriptions.v0.subscription-updated` is sent when the subscription is updated. - `org.camaraproject.device-data-volume-subscriptions.v0.subscription-ended` is sent when the subscription ends. It is used in following cases: - the subscription expire time (optionally set by the requester) has been reached - the maximum number of subscription events (optionally set by the requester) has been reached - the subscription was deleted by the requester - the Access Token `sinkCredential` (optionally set by the requester) expiration time has been reached - the API server has to stop sending notification prematurely ### Notification callback This endpoint describes the event notification received on subscription listener side when the event occurred. As for subscription, detailed description of the event notification is provided in the CAMARA API design guideline document. _**WARNING**: This callback endpoint must be exposed on the consumer side as `POST /{$request.body#/sink}`. Developers may provide a callback URL on which notifications regarding device data volume events can be received from the service provider. If an event occurs the application will send events to the provided webhook - 'sink'._ # Authorization and authentication The "Camara Security and Interoperability Profile" provides details of how an API consumer requests an access token. Please refer to Identity and Consent Management (https://github.com/camaraproject/IdentityAndConsentManagement/) for the released version of the profile. The specific authorization flows to be used will be agreed upon during the onboarding process, happening between the API consumer and the API provider, taking into account the declared purpose for accessing the API, whilst also being subject to the prevailing legal framework dictated by local legislation. In cases where personal data is processed by the API and users can exercise their rights through mechanisms such as opt-in and/or opt-out, the use of three-legged access tokens is mandatory. This ensures that the API remains in compliance with privacy regulations, upholding the principles of transparency and user-centric privacy-by-design. # Identifying the device from the access token This API requires the API consumer to identify a device as the subject of the API as follows: - When the API is invoked using a two-legged access token, the subject will be identified from the optional `device` object, which therefore MUST be provided. - When a three-legged access token is used however, this optional identifier MUST NOT be provided, as the subject will be uniquely identified from the access token. This approach simplifies API usage for API consumers using a three-legged access token to invoke the API by relying on the information that is associated with the access token and was identified during the authentication process. ## Error handling: - If the subject cannot be identified from the access token and the optional `device` object is not included in the request, then the server will return an error with the `422 MISSING_IDENTIFIER` error code. - If the subject can be identified from the access token and the optional `device` object is also included in the request, then the server will return an error with the `422 UNNECESSARY_IDENTIFIER` error code. This will be the case even if the same device is identified by these two methods, as the server is unable to make this comparison. # Additional CAMARA error responses The list of error codes in this API specification is not exhaustive. Therefore the API specification may not document some non-mandatory error statuses as indicated in `CAMARA API Design Guide`. Please refer to the `CAMARA_common.yaml` of the Commonalities Release associated to this API version for a complete list of error responses. The applicable Commonalities Release can be identified in the `API Readiness Checklist` document associated to this API version. As a specific rule, error `501 - NOT_IMPLEMENTED` can be only a possible error response if it is explicitly documented in the API. # Further info and support (FAQs will be added in a later version of the documentation) license: name: Apache 2.0 url: https://www.apache.org/licenses/LICENSE-2.0.html version: wip x-camara-commonalities: 0.6 externalDocs: description: Project documentation at CAMARA url: https://github.com/camaraproject/DeviceDataVolume servers: - url: "{apiRoot}/device-data-volume-subscriptions/vwip" variables: apiRoot: default: http://localhost:9091 description: API root tags: - name: Device Data Volume Subscriptions description: Manage subscriptions to device data volume usage events. paths: /subscriptions: post: tags: - Device data volume subscription summary: "Create a device data volume event subscription" description: Create a subscription for data volume usage events operationId: createDeviceDataVolumeSubscription parameters: - $ref: "#/components/parameters/x-correlator" security: - openId: - device-data-volume-subscriptions:org.camaraproject.device-data-volume-subscriptions.v0.data-50-percent:create - device-data-volume-subscriptions:org.camaraproject.device-data-volume-subscriptions.v0.data-75-percent:create - device-data-volume-subscriptions:org.camaraproject.device-data-volume-subscriptions.v0.data-90-percent:create - device-data-volume-subscriptions:org.camaraproject.device-data-volume-subscriptions.v0.data-exceeded:create requestBody: content: application/json: schema: $ref: "#/components/schemas/SubscriptionRequest" required: true callbacks: notifications: "{$request.body#/sink}": post: summary: "notifications callback" description: | Important: this endpoint is to be implemented by the API consumer.

Subscription is fully operative. - `INACTIVE`: Subscription is temporarily inactive, but its workflow logic is not deleted. - `EXPIRED`: Subscription is ended (no longer active). This status applies when subscription is ended due to `SUBSCRIPTION_EXPIRED` or `ACCESS_TOKEN_EXPIRED` event. - `DELETED`: Subscription is ended as deleted (no longer active).

The API invoker can provide multiple identifiers to be compatible across different network operators. In this case the identifiers MUST belong to the same device. NOTE2: as for this Commonalities release, we are enforcing that the networkAccessIdentifier is only part of the schema for future-proofing, and CAMARA does not currently allow its use. After the CAMARA meta-release work is concluded and the relevant issues are resolved, its use will need to be explicitly documented in the guidelines. type: object properties: phoneNumber: $ref: "#/components/schemas/PhoneNumber" networkAccessIdentifier: $ref: "#/components/schemas/NetworkAccessIdentifier" ipv4Address: $ref: "#/components/schemas/DeviceIpv4Addr" ipv6Address: $ref: "#/components/schemas/DeviceIpv6Address" minProperties: 1 DeviceResponse: description: | An identifier for the end-user equipment able to connect to the network that the response refers to. This parameter is only returned when the API consumer includes the `device` parameter in their request (i.e. they are using a two-legged access token), and is relevant when more than one device identifier is specified, as only one of those device identifiers is allowed in the response. If the API consumer provides more than one device identifier in their request, the API provider must return a single identifier which is the one they are using to fulfil the request, even if the identifiers do not match the same device. API provider does not perform any logic to validate/correlate that the indicated device identifiers match the same device. No error should be returned if the identifiers are otherwise valid to prevent API consumers correlating different identifiers with a given end user. allOf: - $ref: "#/components/schemas/Device" - maxProperties: 1 PhoneNumber: description: A public identifier addressing a telephone subscription.

If the allocated and observed IP addresses are the same (i.e. NAT is not in use) then the same address should be specified for both publicAddress and privateAddress. If NAT64 is in use, the device should be identified by its publicAddress and publicPort, or separately by its allocated IPv6 address (field ipv6Address of the Device object) In all cases, publicAddress must be specified, along with at least one of either privateAddress or publicPort, dependent upon which is known.
