You can use APIM management api to get the subscription ID. In your APIM Instance>Management API There you can find the management url and the token to call the endpoint can be generated.

Specifically to get all subscriptions, you can use below endpoint within management url : GET: https://{your management url}/subscriptions/?api-version=2018-01-01 Or specifically for a product

https://{your management url}/products/{productId}/subscriptions?api-version=2018-01-01

Below is the Rest API reference https://docs.microsoft.com/en-us/rest/api/apimanagement/subscription

Or within a APIM policy, you can find using context variables. https://docs.microsoft.com/en-us/azure/api-management/api-management-policy-expressions

context.Subscription.Id

Fo those who are not clear on the answer provided by @VinuBibin, you can get the subscription id during request, inside the policy and inject it into headers as follows:

    <set-header name="subscription" exists-action="override">
        <value>@(context.Subscription.Id)</value>
    </set-header>
