How to get subscriber ID of an API in Azure APIM?

Question

I am new to Azure APIM and want to know how to get subscriber ID or anything which can uniquely identifies every subscriber of my API.

Yes in APIM. Firstly i want to get the value of that attribute which can uniquely identifies each subscriber then I need to append specific attributes in the request based on that subscriber. — Zain Khan, Sep 27 '18 at 11:11

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://learn.microsoft.com/en-us/rest/api/apimanagement/subscription

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

context.Subscription.Id

the REST API suggested didn't worked for me. Is there any other mean to get the APIM subscription ID? — gsscoder, Oct 16 '20 at 05:55
That is so strange. I think you doesnt enabled the option of Rest api in the portal. — VinuBibin, Oct 21 '20 at 19:14

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>
