Questions:
- Can we send PHP variable values to n8n?
- Can we build a contact form with n8n on the static website?
- Can we trigger a Workflow from outside of n8n?
Yes. It’s possible.
No matter you’re using PHP or JavaScript on your website. You can use this
<?php
$curl = curl_init();
curl_setopt_array($curl, [
CURLOPT_URL => "YOUR n8n WEBHOOK URL here", //Your n8n webhook URL
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => "Name=Hello&Email=hello%40gmail.com", //Data you want to send
CURLOPT_HTTPHEADER => [
"Content-Type: application/x-www-form-urlencoded"
],
]);
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}
JavaScript:
<script>
fetch("YOUR n8n WEBHOOK URL here", { //Replace with n8n URL
"method": "POST",
"headers": {
"Content-Type": "application/x-www-form-urlencoded"
},
"body": {
"Name": "Hello", // Data you wan't to send
"Email": "hello@gmail.com" // Data you wan't to send
}
})
.then(response => {
console.log(response);
})
.catch(err => {
console.error(err);
});
</script>
Warning: Protect your Webhook URL with env to hide it from Public
NodeJS using Axios:
var axios = require("axios").default;
var options = {
method: 'POST',
url: 'YOUR n8n WEBHOOK URL here', //Replace with your URL
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
data: {Name: 'Hello', Email: 'hello@gmail.com'} //Data you want to send
};
axios.request(options).then(function (response) {
console.log(response.data);
}).catch(function (error) {
console.error(error);
});
Python:
import requests
url = "YOUR n8n WEBHOOK URL here"
payload = "Name=Hello&Email=hello%40gmail.com"
headers = {"Content-Type": "application/x-www-form-urlencoded"}
response = requests.request("POST", url, data=payload, headers=headers)
print(response.text)
Using this script can start and send data to n8n.
You have to modify this in order to work as per your requirement.
