Partner Center submission API onboarding

  • Article

Use the Partner Center submission API to programmatically query, create submissions for, and publish commercial marketplace offers. This API is useful if your account manages many offers and you want to automate and optimize the submission process for these offers.

API prerequisites

The Partner Center submissions API requires a few programmatic assets:

  • a Microsoft Entra application
  • a Microsoft Entra access token

Step 1: Complete prerequisites for using the Partner Center submission API

Before you start writing code to call the Partner Center submission API, ensure you've completed the following prerequisites.

  • You (or your organization) must have a Microsoft Entra directory and you must have Global administrator permission for the directory. If you already use Microsoft 365 or other business services from Microsoft, you already have Microsoft Entra directory. Otherwise, you can create a new Microsoft Entra ID in Partner Center at no additional charge.
  • You must associate a Microsoft Entra application with your Partner Center account and obtain your tenant ID, client ID, and key. You need these to obtain the Microsoft Entra access token you will use in calls to the Microsoft Store submission API.

Associate a Microsoft Entra application with your Partner Center account

To use the Partner Center submission API, you must associate a Microsoft Entra application with your Partner Center account, retrieve the tenant ID and client ID for the application, and generate a key. The Microsoft Entra application represents the app or service from which you want to call the Partner Center submission API. You need the tenant ID, client ID, and key to obtain a Microsoft Entra access token to pass to the API.

Note

You only need to perform this task once. After you have the tenant ID, client ID and key, you can reuse them any time you need to create a new Microsoft Entra access token.

  1. In Partner Center, associate your organization's Partner Center account with your organization's Microsoft Entra directory.

  2. From the Users page in the Account settings section of Partner Center, add the Microsoft Entra application that represents the app or service you will use to access submissions for your Partner Center account. Ensure you assign this application the Manager role. If the application doesn't exist yet in your Microsoft Entra directory, create a new Microsoft Entra application in Partner Center.

  3. Return to the Users page, select the name of your Microsoft Entra application to go to the application settings, and copy the Tenant ID and Client ID values.

  4. Select Add new key. On the following screen, copy the Key value. You won't be able to access this info again after you leave this page. For more information, see Manage keys for a Microsoft Entra application.

Step 2: Obtain a Microsoft Entra access token

Before you call any of the methods in the Partner Center submission API, you must first obtain a Microsoft Entra access token to pass to the Authorization header of each method in the API. An access token expires 60 minutes after issuance. After that, you can refresh it so you can use it in future calls to the API.

To obtain the access token, follow the instructions in Service to Service Calls Using Client Credentials to send an HTTP POST to the https://login.microsoftonline.com/<tenant_id>/oauth2/token endpoint. Here is a sample request:

POST https://login.microsoftonline.com/<tenant_id>/oauth2/token HTTP/1.1
Host: login.microsoftonline.com
Content-Type: application/x-www-form-urlencoded; charset=utf-8

grant_type=client_credentials
&client_id=<your_client_id>
&client_secret=<your_client_secret>
&resource= https://api.partner.microsoft.com

For the tenant_id value in the POST URI and the client_id and client_secret parameters, specify the tenant ID, client ID and the key for your application that you retrieved from Partner Center in the previous section. For the resource parameter, you must specify https://api.partner.microsoft.com.

Step 3: Use the Partner Center submission API

After you have a Microsoft Entra access token, call methods in the Partner Center submission API. To create or update submissions, you typically call multiple methods in the Partner Center submission API in a specific order. For information about each scenario and the syntax of each method, see the Ingestion API Swagger.
