Sending POST Request to Get Token Returns Error

[chialuka]

I've been trying to send a POST request to get the token but I keep getting an error from the API saying the request is invalid. I'm using Node.js.

  const token = await axios({
    method: 'post',
    url: 'https://icdaccessmanagement.who.int/connect/token',
    data: {
	client_id: ICD_CLIENT_ID,
	client_secret: ICD_CLIENT_SECRET,
	scope: 'icdapi_access',
	grant_type: 'client_credentials',
    },
  });
  return token;

The request returns a 400 status code with response: data: { error: 'invalid_request' }

I'm not sure where the problem is from and I'd appreciate any help.

Hello,

I am experiencing the same error as @chialuka. I have already tried the same code he shared and an alternative explained in the ICD API Authentication docs shared here.

import fetch from "node-fetch";
import 'dotenv/config'

const scope = "icdapi_access";

const clientID = process.env.CIE_CLIENT_ID;
const clientSecret = process.env.CIE_CLIENT_SECRET;
const tokenEndpoint = process.env.TOKEN_ENDPOINT;

let base64encodedData = Buffer.from(clientID + ':' + clientSecret).toString('base64');

const getNewAuthToken = async () => {
    const token = await fetch(tokenEndpoint, {
        method: 'POST',
        headers: {
            "Content-Type": "application/json",
            'Authorization': 'Basic ' + base64encodedData,
            grant_type: "client_credentials",
            scope
        },
    })

    return token;
}

Does anyone knows how to solve this?

@d-cifuentes, I finally solved it by setting "Content-type" as "application/x-www-form-urlencoded"

I found this by searching through the headers sent in their Swagger API documentation.

This is what my final request looks like:

const response = await axios({
	method: 'post',
	url: icdTokenUrl,
	headers: {
		'Content-Type': 'application/x-www-form-urlencoded',
	},
	data: {
		client_id: ICD_CLIENT_ID,
		client_secret: ICD_CLIENT_SECRET,
		scope: 'icdapi_access',
		grant_type: 'client_credentials',
	},
});

Thank you so much!

You have no idea how many hours i had spent until this moment.

@d-cifuentes, you're welcome!

And I totally understand. I spent weeks on it. Had to leave it and then found the solution when I came back to it after about 6 months :)

where do you guys get the information?

client_id, client_secret

I'm very new to ICD-10 stuff.
