Why does my Axios API request return a 401 error while Postman works?
I’m using Axios in a Node.js application to make API requests with different authentication methods (Basic Auth, API Key, and Bearer Token). While these requests work perfectly in Postman, they return a 401 Unauthorized error in my code.
Here’s what I’ve tried:
- Verified that my credentials (username, password, API key, and bearer token) are correct and tested them successfully in Postman
- Checked that the Axios configuration (headers, params, and authentication) matches Postman settings.
- Confirmed the API endpoints are accessible via Postman.
Code Examples:
- Basic Auth:
const response = await axios.get("https://secrets-api.appbrewery.com/all?page=2", {
auth: {
username: TESTING_USER,
password: "TESTING_PASSWORD",
},
});
- API Key:
const response = await axios.get("https://secrets-api.appbrewery.com/filter", {
params: {
score: 5,
apiKey: "MYAPIKEY",
},
});
3.Bearer Token:
const response = await axios.get("https://secrets-api.appbrewery.com/secrets/42", {
headers: {
Authorization: "Bearer MYTOKEN",
},
});
Expected Behavior: The API should return data as it does in Postman.
Actual Behavior: I receive this error for Basic Auth, API Key, and Bearer Token requests:
Error: Request failed with status code 401
Additional Information: Axios version: 1.4.0 Node.js version: v20.11.1 Postman tests work with the same credentials and endpoints.
Question: Why does Axios return a 401 error while Postman works with the same credentials and endpoints? Are there any differences in how Axios and Postman handle authentication? How can I resolve this issue?

Axios returns a 401 error because it requires precise configuration for headers and authentication, unlike Postman, which may handle encoding and defaults automatically; ensure Axios matches Postman settings exactly.
Using this format
const response = await axios.get('https://secrets-api.appbrewery.com/secrets/42', {
headers: {
'Content-Type': 'application/json',
'Authorization': 'Bearer <your-Token>'
}
});
const response1 = await axios.get('https://secrets-api.appbrewery.com/all', {
params: {
'page': '1'
},
auth: {
username: '<your-username>',
password: '<your-password>'
},
headers: {
'Content-Type': 'application/json'
}
});
const response2 = await axios.get('https://secrets-api.appbrewery.com/filter', {
params: {
'score': '5',
'apiKey': '<your-apikey>'
},
headers: {
'Content-Type': 'application/json'
}
});
demo.js
const axios = require('axios');
(async () => {
try {
const response = await axios.get('https://secrets-api.appbrewery.com/secrets/42', {
headers: {
'Content-Type': 'application/json',
'Authorization': 'Bearer 6f279dd4-d65b-4971-bc6a-bde5ab3c5085'
}
});
console.log('Response from /secrets/42:', response.data);
} catch (error) {
console.error('Error fetching /secrets/42:', error.message);
}
try {
const response1 = await axios.get('https://secrets-api.appbrewery.com/all', {
params: {
'page': '1'
},
auth: {
username: 'my-username',
password: 'my-password'
},
headers: {
'Content-Type': 'application/json'
}
});
console.log('Response from /all:', response1.data);
} catch (error) {
console.error('Error fetching /all:', error.message);
}
try {
const response2 = await axios.get('https://secrets-api.appbrewery.com/filter', {
params: {
'score': '5',
'apiKey': '6eaddd2f-6ecf-499d-8a8a-9cd6adf70bc5'
},
headers: {
'Content-Type': 'application/json'
}
});
console.log('Response from /filter:', response2.data);
} catch (error) {
console.error('Error fetching /filter:', error.message);
}
})();
