Add HTTP headers to request

You can add your custom headers to a request.

Headers are passed as JSON in headers parameter.

tip

Remember to encode this parameter like in the example below.

Example

In the example below, we add two headers:

Date: Mon, 12 Dec 2022 07:28:00 GMT,
X-Custom-Header: value.

These headers will be forwarded to the requested page.

JavaScript

curl -G \
--data-urlencode 'url=https://httpbin.org/headers' \
--data-urlencode 'headers={"date": "Mon, 12 Dec 2022 07:28:00 GMT", "x-custom-header": "value"}' \
'https://scraping.narf.ai/api/v1/?api_key=[your API key]'

import requests
import json
from urllib.parse import quote_plus

url = quote_plus("https://httpbin.org/headers")
api_key = "[your API key]"
headers = quote_plus(
    json.dumps({
        "date": "Mon, 12 Dec 2022 07:28:00 GMT",
        "x-custom-header": "value"
        })
)

print(requests.get(f"https://scraping.narf.ai/api/v1/?api_key={api_key}&url={url}&headers={headers}").content)

import axios from "axios";

const url = encodeURIComponent("https://httpbin.org/headers");
const apiKey = "[your API key]";
const headers = encodeURIComponent(
  JSON.Stringify({
    "date": "Mon, 12 Dec 2022 07:28:00 GMT",
    "x-custom-header": "value",
  })
);

const response = await axios.get(
  `https://scraping.narf.ai/api/v1/?api_key=${apiKey}&url=${url}&headers=${headers}`
);
console.log(response.data);

In the response from https://httpbin.org, you will be able to validate that the desired headers were indeed included in the request:
