I am glad to know dreamreal@gmail.com that your issue has been solved. To everyone else please post only working and complete solutions.

Okay, thank you - you’re right, using a different approach worked through the issues. The code I used, BTW, looked like this, as generated verbatim by Postman but with data replaced with gibberish:

var axios = require('axios')
var FormData = require('form-data')
var data = new FormData()
data.append('language', 'english')
data.append('url', 'https://jlhagsdljghaskjhaksjdhgasd')

var config = {
  method: 'post',
  url: 'https://text-analysis12.p.rapidapi.com/article-extraction/api/v1.3',
  headers: {
    'X-RapidAPI-Host': 'text-analysis12.p.rapidapi.com',
    'X-RapidAPI-Key': 'lkjsldkjhalskdlakshdlakjhsdlkjahsd',
    ...data.getHeaders()
  },
  data: data
}

axios(config)
  .then(function (response) {
    console.log(JSON.stringify(response.data))
  })
  .catch(function (error) {
    console.log(error)
  })

This code can be (and will be) optimized, but it works better than the sample code offered through RapidAPI.

The test code is auto-generated by RapidAPI. It is not correct always for all languages and frameworks. You can try postman’s auto code generation it does a better job sometimes. When you get “validation error” with 200 status code it means that everything works correctly on our end. Your client side code has not been formatted correctly.
