Why not rely only on session?<\/strong>
In Magento 2, developers often use customerSession<\/em><\/code> to fetch the logged-in customer ID.
<\/p>\n\n\n\n

However, this may fail if full-page cache or Varnish serves a cached page where session data is not available.<\/p>\n\n\n\n

Using UserContextInterface<\/strong><\/p>\n\n\n\n

To solve this, Magento provides UserContextInterface<\/em><\/code>.
This interface returns the customer ID without depending directly on session values.<\/p>\n\n\n\n

Example implementation<\/strong><\/p>\n\n\n\n

You can inject UserContextInterface<\/em><\/code> into a helper or class:<\/p>\n\n\n\n

namespace Vendor\\Customer\\Helper;\n\nuse Magento\\Framework\\App\\Helper\\AbstractHelper;\nuse Magento\\Authorization\\Model\\UserContextInterface;\n\nclass Data extends AbstractHelper\n{\n    private $userContext;\n\n    public function __construct(\n        \\Magento\\Framework\\App\\Helper\\Context $context,\n        UserContextInterface $userContext\n    ) {\n        parent::__construct($context);\n        $this->userContext = $userContext;\n    }\n\n    public function getCustomerId(): ?int\n    {\n        return $this->userContext->getUserId();\n    }\n}<\/pre>\n\n\n\n
This retrieves the customer ID if the context is set.
Otherwise, it safely returns null<\/em><\/code>.<\/p>\n\n\n\n
When to use UserContext vs Session<\/strong><\/p>\n\n\n\n
You should use UserContext<\/strong> when working with APIs, GraphQL, or AJAX calls that may bypass session.
In these cases, it handles identity even under caching and token-based authentication.<\/p>\n\n\n\n
On the other hand, session<\/strong> works well on traditional storefront flows where customer login relies on PHP session cookies.<\/p>\n\n\n\n
Therefore, session is usually more reliable for frontend templates and blocks.<\/p>\n\n\n\n
Combining both for reliability<\/strong><\/p>\n\n\n\n
A hybrid approach gives better coverage across scenarios.
Check session first, and if not available, then fall back to UserContext<\/em><\/code>.<\/p>\n\n\n\n
if ($this->customerSession->isLoggedIn()) {\n    return (int) $this->customerSession->getCustomerId();\n}\nreturn (int) $this->userContext->getUserId() ?: null;<\/pre>\n\n\n\n
This way, both session-driven pages and API calls can work seamlessly.<\/p>\n\n\n\n
Related session-based approach<\/strong><\/p>\n\n\n\n
If you still want to use session while cache is enabled, Magento provides safe methods.
For details, see our guide: How to Get Customer Data from Session When Cache Enabled<\/a>.<\/p>\n\n\n\n
Learn more<\/strong><\/p>\n\n\n\n
For official reference, check the Adobe DevDocs on User Context<\/a> .<\/p>\n\n\n\n
Conclusion<\/strong><\/p>\n\n\n\n
In conclusion, UserContextInterface<\/em><\/code> is ideal for API or cache-heavy environments.
Meanwhile, session remains the go-to option for regular frontend flows.<\/p>\n\n\n\n
By combining both approaches, you ensure reliable customer ID retrieval across all scenarios in Magento 2.<\/p>\n","protected":false},"excerpt":{"rendered":"
