'Content-Type': 'application/x-www-form-urlencoded'},

how to call API from axios with header

I want to call the API POST method with axios, I did it with postman with header configuration like, and it return the results
and the body request looks :
it return error when I call by axios this my script, anyone can help me what I suppose todo from the axios side ?
const header = {
headers: {
'Content-Transfer-Encoding': 'application/json',
'content-type': 'application/json',
'HTTP_API_KEY': 'xxxxx',
}
}
axios({
method: 'POST',
url: URL,
headers: header,
data : {
}
})
.then((response) => {
if (response.status !== 200) {
return res.send(respone("500", response.data.result.data))
} else {
return res.send(respone("200", response.data.result.data))
}
})
.catch((error) => {
console.log(error);
return res.send(error)
})
the error show
{
"message": "Request failed with status code 404",
"name": "AxiosError",
"config": {
"transitional": {
"silentJSONParsing": true,
"forcedJSONParsing": true,

"Content-Length": 2
},
"method": "post",
"url": "xxxxx",
"data": "{}"
},
"code": "ERR_BAD_REQUEST",
"status": 404
}

It seems you nested your headers inside another "headers" property.
Basically you're doing this
headers: {
headers: {
'Content-Transfer-Encoding': ...
}
}

As Zai showed in her answer you problem is your header variable:
const header = {
headers: {
'Content-Transfer-Encoding': 'application/json',
'content-type': 'application/json',
'HTTP_API_KEY': 'xxxxx',
}
}
is nested, when you do this:
axios({
method: 'POST',
url: URL,
headers: header,
data : {
}
what you are really doing is:
axios({
method: 'POST',
url: URL,
headers: headers: {
'Content-Transfer-Encoding': 'application/json',
'content-type': 'application/json',
'HTTP_API_KEY': 'xxxxx',
},
data : {
}
So your header: instead of being Content-transfer etc... is just 'headers'
try this:
const header = {
'Content-Transfer-Encoding': 'application/json',
'content-type': 'application/json',
'HTTP_API_KEY': 'xxxxx',
}
also, i recommend you to do a console.log with your api call in order to find this problems faster and compare with postman, really helpful in develop phase (just use it in local, never push that log to production)

{"error":"unsupported_grant_type","error_description":"grant_type parameter is missing"} for Spotify API

Using Spotify Documentation for Client Credential Flow
(https://developer.spotify.com/documentation/general/guides/authorization/client-credentials/)
I was able to create an API request in javascript:
function getoAuth () {
const client_id = id;
const client_secret = secret;
fetch("https://accounts.spotify.com/api/token", {
method: 'POST',
headers: {
'Content-type': 'application/x-www-form-urlencoded',
'Authorization': 'Basic' + (client_id + ":" + client_secret).toString('base64')
},
form: {
grant_type: 'client_credentials',
},
json: true
})
}
But I'm receiving the following error: {"error":"unsupported_grant_type","error_description":"grant_type parameter is missing"}
Why is this failing?

Check the fetch library docs, you have to pass the formdata through body field.
https://developer.mozilla.org/en-US/docs/web/api/fetch
fetch("https://accounts.spotify.com/api/token", {
method: 'POST',
headers: {
'Content-type': 'application/x-www-form-urlencoded',
'Authorization': 'Basic<>'
},
body: new URLSearchParams({
'grant_type': 'client_credentials'
}),
json: true
})

Node Javascript Tiny CC

I am trying to use the tiny.cc REST API from Node, but seem to be hitting an issue since the Server always responds with a message 'Missing input parameters'.
var message = JSON.stringify({
"urls": [
{
"long_url": "http://example.com",
}
]
});
var https_options = {
host: 'tinycc.com',
path: '/tiny/api/3/urls/',
port: 443,
method: 'POST',
headers: {
'Authorization': 'Basic XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
'Content-Length': message.length
}
}
var req = https.request(https_options,res => {
var msg = '';
res.on('data',d => msg += d);
res.on('end',() => {
console.log('end',JSON.parse(msg));
});
});
req.on('error',e => console.log('tinyURL error',e));
req.write(message);
req.end();
The response is always
{
error: {
code: 1305,
message: 'Missing input parameters',
details: ''
},
version: '3.1'
}

I don't know which library are you using for making the API call, but I think you will be better using request and including your payload as the body on your post request rather than using the more manual method of writing to the request.
var message = {
"urls": [
{
"long_url": "http://example.com",
}
]
};
var options = {
host: 'tinycc.com',
path: '/tiny/api/3/urls/',
port: 443,
method: 'POST',
body: message,
json: true,
headers: {
'Authorization': 'Basic XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
'Content-Length': message.length,
"Content-Type": "application/json"
}
}
request(options, console.log)

Mailchimp api to subscribe using java script request issue

I am trying below javascript code to subscribe on mailchimp. flow wise working good but i am getting error like not authorize because may be i am not passing api key correctly. please help to solve my issue
var request = new Request('https://<dc>.api.mailchimp.com/3.0/lists/[listid]/members', {
method: 'POST',
mode: 'no-cors',
json: {
"email_address": "am_it#live.com",
"status": "subscribed",
},
redirect: 'follow',
headers: new Headers({
'Content-Type': 'application/json',
'Authorization': 'Basic apikey'
})
});
// Now use it!
fetch(request).then(function (data) {
console.log(data);
});

You need to add your authentification details with your username and api key. You can do it with the auth parameter:
auth: {
'user': 'yourUserName',
'pass': 'yourApiKey'
}
Just add that to your request object:
Request('https://<dc>.api.mailchimp.com/3.0/lists/[listid]/members', {
method: 'POST',
mode: 'no-cors',
json: {
"email_address": "am_it#live.com",
"status": "subscribed",
},
redirect: 'follow',
headers: new Headers({
'Content-Type': 'application/json',
'Authorization': 'Basic apikey'
}),
auth: {
'user': 'yourUserName',
'pass': 'yourApiKey'
}
});
I looked at the documentation in the getting started section of the developer mailchimp api: here and I converted the curl examples to javascript code using this page. Let me know if it worked.
