+
+<APIMethod
+  path="/subscription/billing-portal"
+  method="POST"
+  requireSession

+```ts
+type createBillingPortal = {
+    /**
+     * Reference id of the subscription to upgrade. 
+     */
+    referenceId?: string = "123"
+    /**
+     * Return URL to redirect back after successful subscription. 
+     */
+    returnUrl?: string
+}
+```
+</APIMethod>
+        
+This endpoint creates a Stripe billing portal session and returns a URL in the response as `data.url`. You can redirect users to this URL to allow them to manage their subscription, payment methods, and billing history.
+
