How to send a Post request to the Pastebin API vie Code by Zapier and fetch?

Question

I'm trying to formulate a post request to the Pastebin API in Code by Zapier using fetch. After some trial and error, I managed to do it using URLencoded data, like this:

const { URLSearchParams } = require('url');
const encodedParams = new URLSearchParams();


encodedParams.set('api_paste_code', 'test');
encodedParams.set('api_option', 'paste');
encodedParams.set('api_dev_key', '1NLa6pHlhuBYTMAb1GDiAYHa1xAy5Ihd');


let url = 'https://pastebin.com/api/api_post.php';

let options = {
  method: 'POST',
  headers: {'Content-Type': 'application/x-www-form-urlencoded'},
  body: encodedParams.toString()
};

const fetchResult = await fetch(url, options);


output =  {output: fetchResult}

I get the response 200 but the data I receive is something I've never seen in my life. It's something like this:

And then it continues with these rows of numbers for thousands of lines. I tried to use decodeURIcomponent but the returned value is [object Object] that I can't parse into a string.

I suspect maybe parsing encodedParams to string before sending can cause the proble as in Node in my IDE and in postman I don't use toString() and I have the correct response with the url to my paste. But in Zappier if I use the same code I get the response 422 "Unprocessable Entity". Only after parsing encodedParams to string did I manage to get a response code 200. I'm stuck.

I hope my question is formatted ok, this is my first time on StackOverflow. Thanks!

Answer 1

This is actually working, you can see in your response you have a status of 200, the problem is, you didn't extract the data out of the HTTP response.

You need to make this change to see the actual data:

const fetchResult = await fetch(url, options);
const data = await fetchResult.json();

output =  {output: data}

You could also replace .json() with .text() if you prefer.

I hope this helps!
