How can I make multiple subscriptions in the same tenant with microsoft graph?

Question

I have a scenario where I want to be able to make multiple subscriptions to Microsoft graph in the same tenant. But when I try to do so, even thought the resource of my post request is different from the first subscription, it will show me the following message:

"Status Code: Conflict; Reason: A subscripton already exists. It must be deleted before a another can be made."

Example:
This are the parameters I am using for my first subscription which is successful:

let presenceSubscriptionOptions = {
  method: "POST",
  url: "https://graph.microsoft.com/v1.0/subscriptions",
  headers: {
	"Content-Type": "application/json",
	Authorization: userToken,
  },
  data: JSON.stringify({
	changeType: "updated",
	clientState: "MyGraphExplorerSecretClientState",
	notificationUrl: notificationUrl,
	resource: "/communications/presences?$filter=id in ('70c5d24f-82b0-443f-8d7f-5acd754f2467','7287a48e-6f92-4cb2-ac8e-af236db330ae','90e78e73-4c99-44a6-8dcb-5616bbd24ce0','438a42cb-772d-44bc-95cc-cf63cdd78c93')",
	expirationDateTime: expirationDateTime,
  }),
};

This are the parameters I am using for my second subscription which is unsuccessful:

let presenceSubscriptionOptions = {
  method: "POST",
  url: "https://graph.microsoft.com/v1.0/subscriptions",
  headers: {
	"Content-Type": "application/json",
	Authorization: userToken,
  },
  data: JSON.stringify({
	changeType: "updated",
	clientState: "MyGraphExplorerSecretClientState",
	notificationUrl: notificationUrl,
	resource: "/communications/presences?$filter=id in ('70c5d24f-82b0-443f-8d7f-5acd754f2467','7287a48e-6f92-4cb2-ac8e-af236db330ae','0b167637-747c-420f-acb7-9830c1a35d3d','438a42cb-772d-44bc-95cc-cf63cdd78c93','90e78e73-4c99-44a6-8dcb-5616bbd24ce0')",
	expirationDateTime: expirationDateTime,
  }),
};

The change in both is a user id in the resource and the userToken.

Is the problem with my post request parameter? An azure AD configuration or something else?

Hi @TiagoC , unfortunately only one tenant can be associated with a single subscription. Unless I misunderstand your question, this can't be accomplished. Please let me know if you have any questions and I can help you further.

If this answer helps you please mark it as "Verified" so other users can reference it.

Thank you,

James

@Prajakta Kenjale -Yes. You can create multiple subscription with different User Id.
