Customer Info: How to Get Bearer Token in Magento 2

Customer Info: How to Get Bearer Token in Magento 2, When you’re working with Magento 2 GraphQL APIs, some data is public (like products or categories), but some — like customer details — require authentication.
To access customer-specific data, you need a bearer token.

In this guide, we’ll walk you through how to generate a bearer token and use it to fetch authenticated customer info in Magento 2.

Customer Info: How to Get Bearer Token in Magento 2

🔑 What is a Bearer Token?

A bearer token is like a key that proves your identity to the Magento server. Once you have it, you can perform actions that require customer login, such as:

• Fetching customer account details
• Managing addresses
• Viewing order history

Without this token, Magento will block access to sensitive customer information.

🛠 How to Get a Bearer Token in Magento 2

To get a bearer token, you need to log in using the customer’s email and password through a GraphQL mutation.

Here’s how:

Step 1: Setup Postman (or any GraphQL client)

Open Postman and create a POST request to your Magento instance:

https://yourdomain.com/graphql

Make sure you set:

• Method: POST
• Headers:
  • Content-Type: application/json

Step 2: Write the Login Mutation

Use this mutation to get the token:

mutation {
  generateCustomerToken(
    email: "customer@example.com",
    password: "yourpassword123"
  ) {
    token
  }
}

Step 3: Send the Request

If the credentials are correct, Magento will respond with something like:

{
  "data": {
    "generateCustomerToken": {
      "token": "xyz123abcd456..."
    }
  }
}

👉 This token is your “bearer token.”

🧩 How to Use the Bearer Token

Now that you have the token, you need to include it in the request headers when calling any protected GraphQL queries.

Add this in your Postman headers:

Replace xyz123abcd456... with the actual token you received.

🎯 Example: Fetching Customer Info

Now let’s try fetching basic customer information:

query {
  customer {
    firstname
    lastname
    email
  }
}

If your token is correct, Magento will return the customer’s profile information.

🚨 Common Issues

• Invalid Credentials: Make sure the email/password are correct.
• Expired Tokens: Bearer tokens may expire after some time or logout.
• Missing Authorization Header: Always set Authorization: Bearer <your_token>.

✅ Conclusion (Customer Info: How to Get Bearer Token in Magento 2)
