Marketplace metered billing APIs

  • Article

The metered billing APIs should be used when the publisher creates custom metering dimensions for an offer to be published in Partner Center. Integration with the metered billing APIs is required for any purchased offer that has one or more plans with custom dimensions to emit usage events.

Important

You must keep track of the usage in your code and only send usage events to Microsoft for the usage that is above the base fee.

For more information on creating custom metering dimensions for SaaS, see SaaS metered billing.

For more information on creating custom metering dimensions for an Azure Application offer with a Managed app plan, see Configure your Azure application offer setup details.

Enforcing TLS 1.2 Note

TLS version 1.2 version is enforced as the minimal version for HTTPS communications. Make sure you use this TLS version in your code. TLS version 1.0 and 1.1 are deprecated and connection attempts will be refused.

Metered billing single usage event

The usage event API should be called by the publisher to emit usage events against an active resource (subscribed) for the plan purchased by the specific customer. The usage event is emitted separately for each custom dimension of the plan defined by the publisher when publishing the offer.

Only one usage event can be emitted for each hour of a calendar day per resource and dimension. If more than one unit is consumed in an hour, then accumulate all the units consumed in the hour and then emit it in a single event. Usage events can only be emitted for the past 24 hours. If you emit a usage event at any time between 8:00 and 8:59:59 (and it is accepted) and send an additional event for the same day between 8:00 and 8:59:59, it will be rejected as a duplicate.

Query parameters:

Parameter Recommendation
ApiVersion Use 2018-08-31.

Request headers:

Content-type Use application/json
x-ms-requestid Unique string value for tracking the request from the client, preferably a GUID. If this value is not provided, one will be generated and provided in the response headers.
x-ms-correlationid Unique string value for operation on the client. This parameter correlates all events from client operation with events on the server side. If this value isn't provided, one will be generated and provided in the response headers.
authorization A unique access token that identifies the ISV that is making this API call. The format is "Bearer <access_token>" when the token value is retrieved by the publisher as explained for

Request body example:

{
  "resourceId": <guid>, // unique identifier of the resource against which usage is emitted. 
  "quantity": 5.0, // how many units were consumed for the date and hour specified in effectiveStartTime, must be greater than 0 or a double integer
  "dimension": "dim1", // custom dimension identifier
  "effectiveStartTime": "2018-12-01T08:30:14", // time in UTC when the usage event occurred, from now and until 24 hours back
  "planId": "plan1", // id of the plan purchased for the offer
}

For Azure Application Managed Apps plans, the resourceId is the Managed App resource group Id. An example script for fetching it can be found in using the Azure-managed identities token.

For SaaS offers, the resourceId is the SaaS subscription ID. For more details on SaaS subscriptions, see list subscriptions.

Responses

Code: 200
OK. The usage emission was accepted and recorded on Microsoft side for further processing and billing.

Response payload example:

{
  "usageEventId": <guid>, // unique identifier associated with the usage event in Microsoft records
  "status": "Accepted" // this is the only value in case of single usage event
  "messageTime": "2020-01-12T13:19:35.3458658Z", // time in UTC this event was accepted
  "resourceId": <guid>, // unique identifier of the resource against which usage is emitted. For SaaS it's the subscriptionId.
  "quantity": 5.0, // amount of emitted units as recorded by Microsoft
  "dimension": "dim1", // custom dimension identifier
  "effectiveStartTime": "2018-12-01T08:30:14", // time in UTC when the usage event occurred, as sent by the ISV
  "planId": "plan1", // id of the plan purchased for the offer
}

Code: 400
Bad request.

  • Missing or invalid request data provided.
  • effectiveStartTime is more than 24 hours in the past. Event has expired.
  • SaaS subscription isn't in Subscribed status.

Response payload example:

Forbidden. The authorization token isn't provided, is invalid or expired. Or the request is attempting to access a subscription for an offer that was published with a different Microsoft Entra App ID from the one used to create the authorization token.

Code: 409
Conflict. A usage event has already been successfully reported for the specified resource ID, effective usage date and hour.

Response payload example:

{
  "additionalInfo": {
    "acceptedMessage": {

Metered billing batch usage event

The batch usage event API allows you to emit usage events for more than one purchased resource at once. It also allows you to emit several usage events for the same resource as long as they're for different calendar hours. The maximal number of events in a single batch is 25.

POST: https://marketplaceapi.microsoft.com/api/batchUsageEvent?api-version=<ApiVersion>

Query parameters:

Parameter Recommendation
ApiVersion Use 2018-08-31.

Request headers:

Content-type Use application/json
x-ms-requestid Unique string value for tracking the request from the client, preferably a GUID. If this value isn't provided, one will be generated, and provided in the response headers.
x-ms-correlationid Unique string value for operation on the client. This parameter correlates all events from client operation with events on the server side. If this value isn't provided, one will be generated, and provided in the response headers.
authorization A unique access token that identifies the ISV that is making this API call. The format is Bearer <access_token> when the token value is retrieved by the publisher as explained for

Note

In the request body, the resource identifier has different meanings for SaaS app and for Azure Managed app emitting custom meter. The resource identifier for SaaS App is resourceID. The resource identifier for Azure Application Managed Apps plans is resourceUri. For more information on resource identifiers, see Azure Marketplace Metered Billing- Picking the correct ID when submitting usage events.

For SaaS offers, the resourceId is the SaaS subscription ID. For more details on SaaS subscriptions, see list subscriptions.

Request body example for SaaS apps:

{
  "request": [ // list of usage events for the same or different resources of the publisher
    { // first event
      "resourceId": "<guid1>", // Unique identifier of the resource against which usage is emitted. 
      "quantity": 5.0, // how many units were consumed for the date and hour specified in effectiveStartTime, must be greater than 0 or a double integer
      "dimension": "dim1", //Custom dimension identifier
      "effectiveStartTime": "2018-12-01T08:30:14",//Time in UTC when the usage event occurred, from now and until 24 hours back
      "planId": "plan1", // id of the plan purchased for the offer
    },
    { // next event
      "resourceId": "<guid2>", 
      "quantity": 39.0, 
      "dimension": "email", 
      "effectiveStartTime": "2018-11-01T23:33:10
      "planId": "gold", // id of the plan purchased for the offer
    }
  ]
}

For Azure Application Managed Apps plans, the resourceUri is the Managed Application resourceUsageId. An example script for fetching it can be found in using the Azure-managed identities token.

Request body example for Azure Application managed apps:

{
  "request": [ // list of usage events for the same or different resources of the publisher
    { // first event
      "resourceUri": "<fullyqualifiedname>", // Unique identifier of the resource against which usage is emitted. 
      "quantity": 5.0, // how many units were consumed for the date and hour specified in effectiveStartTime, must be greater than 0 or a double integer
      "dimension": "dim1", //Custom dimension identifier
      "effectiveStartTime": "2018-12-01T08:30:14",//Time in UTC when the usage event occurred, from now and until 24 hours back
      "planId": "plan1", // id of the plan purchased for the offer
    }
  ]
}

Development and testing best practices

To test the custom meter emission, implement the integration with metering API, create a plan for your published SaaS offer with custom dimensions defined in it with zero price per unit. And publish this offer as preview so only limited users would be able to access and test the integration.

You can also use private plan for an existing live offer to limit the access to this plan during testing to limited audience.

Get support

Follow the instruction in Support for the commercial marketplace program in Partner Center to understand publisher support options and open a support ticket with Microsoft.
