Hi, Is there a way to subscribe to multiple products in a single subscription in Azure APIM. For eg: Product 1 has API1, API2 and Product2 has API3, API4. Can a consumer create one subscription to subscribe to both Product1 and Product2 so that consumer can call any of the four APIs using a single subscription key. In the portal there is option to create a subscription for a single product or a single API only.

Hi Nagashree, if you want a single Subscription Key to be used for all the APIS, why cant you add all the APIS under one Product and do it. Like in your Example. Product 1 can have API1, API2,API3, API4 and Product2 has API3, API4 So that you can subscribe with one Subscription key with Product1. APIS can be subscribed to Multiple Products. if you want to change the Subscription Key,Then you can use https://learn.microsoft.com/en-us/rest/api/apimanagement/current-ga/subscription/create-or-update#code-try-0 Thanks, Sujith.

Hi @Sujithreddy Komma , thanks for responding. I do understand the workaround you have suggested. However, trying to bundle the products as suggested by you will make the product packaging consumer-focused rather than being business-focused. We want to retain the products to be business-focused rather than creating a different product for each consumer.
I believe the subscription key is unique and you are not allowed to set the same subscription key to multiple subscriptions in APIM. I have tried this with azure powershell commands for the management API and it throws an error if you try to set the same subscription key in multiple subscriptions.

Hi Nagashree,

Thanks Got your Point.
True Subscription key is Unique and we cannot keep the same for multiple Subscriptions in APIM Single Instance.

Just as a workaround you can try by using the Subscription Key which we create at the Service Level Scope which will work.

But the Problem with this is it will work for all the APIs which are present in APIM not only these 2 Products. There is also one more downside for this i think if you have applied any polices at the Product level it will not call them.

Please submit a user feedback as well if this is a requirement at the below link
