I cant do a POST request to paypal API

[Spartano]

Hi, mi issue is more of a question, i am tryng to make axios do a POST request that does the same thing that this curl does:

curl -v https://api.sandbox.paypal.com/v1/oauth2/token \
  -H "Accept: application/json" \
  -H "Accept-Language: en_US" \
  -u "EOJ2S-Z6OoN_le_KS1d75wsZ6y0SFdVsY9183IvxFyZp:EClusMEUk8e9ihI7ZdVLF5cZ6y0SFdVsY9183IvxFyZp" \
  -d "grant_type=client_credentials"

my code is this:

    var instance = axios.create({
        baseURL: 'https://api.sandbox.paypal.com/v1/oauth2/',
        timeout: 1000,
        method: 'post',
        headers: {
          'Accept': 'application/json',
          'Accept-Language': 'en_US',
          'content-type': 'application/x-www-form-urlencoded',
          'EOJ2S-Z6OoN_le_KS1d75wsZ6y0SFdVsY9183IvxFyZp':'EClusMEUk8e9ihI7ZdVLF5cZ6y0SFdVsY9183IvxFyZp'
        },
        data: {
          "grant_type": "client_credentials",
        },    
});

  instance.post('/token')
      .then(function(response){
        console.log(response.data); // ex.: { user: 'Your User'}
        console.log(response.status); // ex.: 200
      });

i am calling it from my localhost, and it gives me the error of 401. This is the link to the PAYPAL API https://developer.paypal.com/docs/integration/direct/make-your-first-call/

Reanding the docs i wasnt able to understand where to put the username and passowrd or how to set up the autorization to basicOuth
instance.defaults.headers.common['Authorization'] = AUTH_TOKEN;
what is AUTH_TOKEN? is a const? what value should i give it?

Anyway, thank you in advance.

You need to authenticate with username and password using basic authentication. Also you're sending JSON with that request and the curl version uses "application/x-www-form-urlencoded ". Please read the documentation:

• https://github.com/mzabriskie/axios#using-applicationx-www-form-urlencoded-format

@Spartano You solved the problem ? I'm trying to do the same thing and give me a 401 too and this message "Authentication failed due to invalid authentication credentials or a missing Authorization header."

My code here:

axios.post('https://api.sandbox.paypal.com/v1/oauth2/token', querystring.stringify({

	grant_type: 'client_credentials',

	withCredentials: true,

  	headers:{

    	'Accept': 'application/json',
    	'Accept-Language': 'en_US',
    	'Content-Type': 'application/x-www-form-urlencoded',
  	},

	auth: {

  		username: 'ClientID',
    	        password: 'Secret'
  	}


})).then((response) => {

	console.log(response);

}).catch((err) => {console.log(err);});

I solved it! I made a Gist to show how I solved it if someone needs help: https://gist.github.com/TigaxMT/b57c11df3e4ebd0510858ec3df775efa
