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:

 output url https://pastebin.com/api/api_post.php status 200 statusText OK headers _headers date 1 Fri, 08 Apr 2022 13:45:23 GMT content-type 1 text/html; charset=UTF-8 transfer-encoding 1 chunked connection 1 close x-custom-api-dev-id 1 8604170 set-cookie 1 pastebin_posted=49abfc325ca96e5daf3e6b81de576fbdae7e584ab1dc300294f770a2200d6771a%3A2%3A%7Bi%3A0%3Bs%3A15%3A%22pastebin_posted%22%3Bi%3A1%3Bs%3A8%3A%22X6WmZQ3u%22%3B%7D; expires=Fri, 08-Apr-2022 14:45:23 GMT; Max-Age=3600; path=/; HttpOnly content-encoding 1 gzip cf-cache-status 1 DYNAMIC expect-ct 1 max-age=604800, report-uri="https://report-uri.cloudflare.com/cdn-cgi/beacon/expect-ct" server 1 cloudflare cf-ray 1 6f8b716dfe295790-IAD ok true body _writeState 0 0 1 0 _readableState objectMode false highWaterMark 16384 buffer head null tail null length 0 length 0 pipes null pipesCount 0 flowing null ended false endEmitted false reading false sync false needReadable false emittedReadable false readableListening false resumeScheduled false emitClose true autoDestroy false destroyed false defaultEncoding utf8 awaitDrainWriters null multiAwaitDrain false readingMore false decoder null encoding null readable true _events _eventsCount 6 _writableState objectMode false highWaterMark 16384 finalCalled false needDrain false ending false ended false finished false destroyed false decodeStrings true defaultEncoding utf8 length 49 writing true corked 0 sync false bufferProcessing false writelen 49 afterWriteTickInfo null bufferedRequest null lastBufferedRequest null pendingcb 1 prefinished false errorEmitted false emitClose true autoDestroy false bufferedRequestCount 0 corkedRequestsFree next null entry null writable true allowHalfOpen true _transformState needTransform false transforming true writechunk type Buffer data 1 31 2 139 3 8 4 0 5 0 6 0 7 0 8 0 9 0 10 3 11 203 12 40 13 41 14 41 15 40 16 182 17 210 18 215 19 47 20 72 21 44 22 46 23 73 24 77 25 202 26 204 27 211 28 75 29 206 30 207 31 213 32 143 33 48 34 11

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

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
