Executing API calls utilizing Axios in a NodeJS environment with the Authorization Basic feature

I have developed an API to retrieve a token from PayPal.

curl -v POST https://api.sandbox.paypal.com/v1/oauth2/token \
  -H "Accept: application/json" \
  -H "Accept-Language: en_US" \
  -u "CLIENT_ID:SECRET" \
  -d "grant_type=client_credentials"

Currently, I am utilizing axios for making the call, but unfortunately facing authentication errors.

axios.post("https://api.sandbox.paypal.com/v1/oauth2/token", {}, {
      auth: {
        username: "xxxx, // clientId
        password: "xxxx"  // client Secret
      }
    }).then(function(response) {
      result = response;
      console.log('Authenticated' + response);
    }).catch(function(error) {
      console.log('Error on Authentication' + error);
    });

It seems like I may have missed including the "grant_type" parameter in this call. How can I correctly pass these parameters in the request? Your assistance is greatly appreciated. Thank you!

Answer №1

${clientId}:${secretKey} must be encoded in base64

If you are using JavaScript, options include btoa(), toString('base64'), or setting the auth key with axios

When using curl, utilize the -u command line parameter.

For general rest API usage, make sure to pass a basic auth to the oauth2/token endpoint by including grant_type=client_credentials in your query string, as outlined here. This will provide you with an access_token for all subsequent API calls.

The 'Connect with PayPal' documentation linked is specific to that integration, requiring an authorization code which isn't necessary for other APIs.

Answer №2

fetch({
     method: 'POST',
     url: 'https://api.sandbox.paypal.com/v1/oauth2/token',
     headers: {
       'Authorization': `Bearer ${accessToken}`,
       'Content-type': 'application/json'
     },
     body: JSON.stringify({ 
         grant_type: 'authorization_code', 
         code: `${authCode}`
      })
})

Answer №3

Make sure to avoid using your username and password as the Client ID and Client Secret. While the -u flag in curl is typically used for authentication, it may work differently with axios. For more information on Curl commands, check out this resource. Remember, there are always alternatives available if you're facing challenges. Consider utilizing the PayPal-node-SDK library or watching tutorials on YouTube.
