Shopify is an extremely popular e-commerce platform, with over a million businesses using it to power their online stores. One important feature of any online store is the ability for customers to login, which enables them to access account information, view order history, and more. In this article, we will explore how to check whether a user is logged in or not in Shopify, along with some example code.
Checking User Login State
Shopify provides a global object called customer that can be used to check whether a user is currently logged in or not. This object contains a variety of properties related to the logged-in customer, such as their customer ID and email address. One way to check whether a user is logged in or not is to use the following code:
{% if customer %}
<p>Welcome, {{ customer.first_name }}!</p>
{% else %}
<p>Please log in to view your account information.</p>
{% endif %}
In this code snippet, we use liquid tags to check whether the customer object exists. If it does, we display a welcome message that includes the customer's first name. If it doesn't, we display a message asking them to log in to view their account information.
This is a simple and effective way to check whether a user is logged in or not, and can be easily customized to fit the needs of your particular store.
Using Liquid Tags to Check User Login Status
Another way to check whether a user is logged in or not is to use liquid tags. Liquid tags are a powerful way to create dynamic content in Shopify, and can be used to display or hide content based on the user's login status.
Here is an example of how to use liquid tags to check whether a user is logged in or not:
{% if customer %}
<p>Welcome, {{ customer.first_name }}!</p>
{% endif %}
In this code, we use the if liquid tag to check whether the customer object exists. If it does, we display a welcome message that includes their first name. If it doesn't, we don't display anything at all.
This is a very simple example, but there are many other ways you can use liquid tags to check the user's login status. For example, you can use the unless tag to display content only if the user is not logged in, like this:
{% unless customer %}
<p>Please log in to view your account information.</p>
{% endunless %}
In this code, we use the unless tag to check whether the customer object does not exist. If it doesn't, we display a message asking the user to log in.
Using Shopify's Rest API
Another way to check whether a user is logged in or not is to use Shopify's REST API. This is a more advanced technique, but can be very powerful if you need to perform more complex actions based on the user's login state.
Here is an example of how to use the REST API to check the user's login status:
$.ajax({
url: '/account.json',
dataType: 'json',
success: function(customer) {
if (customer) {
console.log('User is logged in!');
console.log(customer);
} else {
console.log('User is not logged in!');
}
}
});
In this code, we use the $.ajax method to make a request to the Shopify API at the /account.json endpoint. If the request is successful, we receive a JSON object containing information about the customer, which we can use to check whether they are logged in or not.
This method is more complex than the previous examples, but can be very useful if you need to perform more complex actions based on the user's login state.
Conclusion
In this article, we explored several different methods for checking whether a user is logged in or not in Shopify. Whether you choose to use liquid tags, Shopify's REST API, or a combination of both, Shopify provides powerful tools and utilities to help you build a great online store.

Using Liquid Tags to Check User Login Status
In addition to the examples we provided earlier, there are many other ways you can use liquid tags to check the user's login status. For instance, if you want to display a specific message to customers who are logged in but have not yet placed any orders, you could use the following code:
{% if customer.orders_count == 0 %}
<p>Welcome, {{ customer.first_name }}! You haven't placed any orders yet.</p>
{% elsif customer %}
<p>Welcome back, {{ customer.first_name }}!</p>
{% else %}
<p>Please log in to view your account information.</p>
{% endif %}
In this code, we use the elsif liquid tag to check whether the customer has placed any orders yet. If they haven't, we display a message that includes their first name and lets them know that they haven't placed any orders yet. If they have placed orders, we display a welcome back message. If they are not logged in, we display a message prompting them to log in.
Using Shopify's REST API
Shopify's REST API provides many powerful endpoints that you can use to manage your store programmatically. In addition to checking the user's login status, you can use the REST API to create, read, update, and delete various store objects, such as customers, orders, and products.
Here is an example of how you could use the REST API to retrieve the current user's ID:
$.ajax({
url: '/account.json',
dataType: 'json',
success: function(customer) {
if (customer) {
console.log('User ID: ' + customer.id);
} else {
console.log('User is not logged in!');
}
}
});
In this code, we make an Ajax request to the /account.json endpoint and receive a JSON object containing information about the customer. If the customer is logged in, we print out their ID to the console. If they are not logged in, we display a message indicating that fact.
Of course, this is just a simple example – you could use the REST API to perform many more advanced actions, such as updating a customer's account information, creating a new order, or retrieving a list of all the products in your store.
Conclusion
In conclusion, Shopify provides many powerful tools and utilities for checking the user's login status and managing your store programmatically. Whether you choose to use liquid tags, Shopify's REST API, or a combination of both, you have many options for building a great online store that meets your specific needs.
