Code Examples
Here's how you can integrate PDF generation into your applications:
JavaScript / Node.js
// JavaScript Example
const response = await fetch('https://docuapi.io/api/submit/rental-app-demo', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'X-API-Key': 'pk_your_api_key_here'
},
body: JSON.stringify({
"firstName": "John",
"lastName": "Doe",
"email": "john.doe@example.com",
"phone": "555-123-4567",
"moveInDate": "2024-02-15",
"monthlyIncome": 5000,
"hasPets": true,
"emergencyContact": "Jane Doe",
"emergencyPhone": "555-987-6543"
})
});
const pdfBlob = await response.blob();
const pdfUrl = URL.createObjectURL(pdfBlob);
window.open(pdfUrl); // Opens filled PDFcURL
curl -X POST 'https://docuapi.io/api/submit/rental-app-demo' \
-H 'Content-Type: application/json' \
-H 'X-API-Key: pk_your_api_key_here' \
-d '{
