Discover how to create powerful backend APIs without writing complex code. Learn how AI-powered platforms enable anyone to build, test, and deploy custom APIs with built-in security and database integration.
Building backend APIs has traditionally been the domain of experienced developers. Between setting up servers, writing backend logic, managing databases, and ensuring security, creating even a simple API could take days or weeks. But what if you could build production-ready APIs in minutes, without deep programming knowledge?
Let's look at what building a custom API traditionally requires:
Infrastructure Setup
Backend Development
Security Implementation
Database Management
Testing and Deployment
This complexity means most small businesses and solo entrepreneurs either:
Modern platforms are changing this paradigm entirely. With AI-powered tools, you can now:
Traditional Approach: 3-5 days of development
Vigma Approach: 5-10 minutes Simply tell the AI: "Create a contact form API that validates email addresses, stores submissions in a database, and sends notifications"
The platform automatically:
Traditional Approach: 1-2 weeks
Vigma Approach: 15 minutes
Traditional Approach: 1 week
Vigma Approach: 10 minutes
Vigma's approach combines the best of both worlds: automated API generation with the flexibility of custom code when you need it.
Start by describing your API needs: "I need an API that accepts customer orders with name, email, product, and quantity fields"
The AI instantly creates:
For specific business rules, you can add custom code using a secure sandbox environment:
Example: Order Validation
// Validate order quantity
if (!body.quantity || body.quantity < 1) {
result = {
success: false,
error: 'Invalid quantity',
message: 'Quantity must be at least 1'
};
throw new Error('Validation failed');
}
// Check inventory (example)
const inventory = await prisma.product.findUnique({
where: { name: body.product }
});
if (inventory && inventory.stock < body.quantity) {
result = {
success: false,
error: 'Insufficient inventory',
available: inventory.stock
};
throw new Error('Out of stock');
}
// Process valid order
result = {
success: true,
message: 'Order accepted',
orderId: Date.now().toString(),
data: body
};
This code runs in a secure sandbox with:
Every API automatically includes database capabilities:
Query Your Data
// Find recent submissions
const recentOrders = await prisma.submission.findMany({
where: {
projectId: projectId,
createdAt: {
gte: new Date(Date.now() - 7 * 24 * 60 * 60 * 1000) // Last 7 days
}
},
orderBy: {
createdAt: 'desc'
},
take: 10
});
result = {
success: true,
orders: recentOrders
};
Count and Aggregate
// Get order statistics
const stats = await prisma.submission.count({
where: {
projectId: projectId
}
});
result = {
success: true,
totalOrders: stats,
period: 'all-time'
};
Call external services when needed:
Example: Send to CRM
// Send customer data to CRM
const crmResponse = await fetch('https://api.yourcrm.com/contacts', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': 'Bearer YOUR_API_KEY'
},
body: JSON.stringify({
email: body.email,
name: body.name,
source: 'website'
})
});
const crmData = await crmResponse.json();
result = {
success: true,
message: 'Customer added to CRM',
crmId: crmData.id
};
Example: Payment Processing
// Process payment (example with Stripe)
const paymentResponse = await fetch('https://api.stripe.com/v1/payment_intents', {
method: 'POST',
headers: {
'Authorization': 'Bearer sk_test_...',
'Content-Type': 'application/x-www-form-urlencoded'
},
body: new URLSearchParams({
amount: body.amount * 100,
currency: 'usd',
'metadata[email]': body.email
})
});
const payment = await paymentResponse.json();
result = {
success: true,
clientSecret: payment.client_secret
};
Security is handled automatically, protecting both you and your users:
All custom code runs in an isolated environment that:
Automatic protection against:
Built-in protection against:
All APIs are:
Before going live, test thoroughly using the built-in testing panel:
Test 1: Valid Request
{
"name": "John Doe",
"email": "john@example.com",
"message": "Hello!"
}
Expected Result: 200 OK with success response
Test 2: Missing Required Field
{
"name": "John Doe",
"message": "Hello!"
}
Expected Result: 400 Bad Request with validation error
Test 3: Invalid Email Format
{
"name": "John Doe",
"email": "not-an-email",
"message": "Hello!"
}
Expected Result: 400 Bad Request with email validation error
Once tested, deploy with a single click:
After deployment, integrate your API anywhere:
JavaScript/Fetch
const response = await fetch('https://yourproject.vigma.app/api/contact', {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({
name: 'John Doe',
email: 'john@example.com',
message: 'Hello!'
})
});
const data = await response.json();
console.log(data);
cURL
curl -X POST https://yourproject.vigma.app/api/contact \
-H "Content-Type: application/json" \
-d '{
"name": "John Doe",
"email": "john@example.com",
"message": "Hello!"
}'
Python
import requests
response = requests.post(
'https://yourproject.vigma.app/api/contact',
json={
'name': 'John Doe',
'email': 'john@example.com',
'message': 'Hello!'
}
)
print(response.json())
Create complex workflows by chaining operations:
// Step 1: Validate customer
const customer = await prisma.customer.findUnique({
where: { email: body.email }
});
if (!customer) {
result = { success: false, error: 'Customer not found' };
throw new Error('Invalid customer');
}
// Step 2: Check eligibility
if (customer.status !== 'active') {
result = { success: false, error: 'Account not active' };
throw new Error('Inactive account');
}
// Step 3: Process request
const response = await fetch('https://api.service.com/process', {
method: 'POST',
headers: { 'Authorization': 'Bearer KEY' },
body: JSON.stringify({ customerId: customer.id, action: body.action })
});
// Step 4: Return result
result = {
success: true,
data: await response.json()
};
Handle different scenarios based on input:
// Route based on request type
if (body.type === 'urgent') {
// Send immediate notification
await fetch('https://api.sms.com/send', {
method: 'POST',
body: JSON.stringify({
to: '+1234567890',
message: `Urgent request from ${body.email}`
})
});
result = {
success: true,
message: 'Urgent request processed',
priority: 'high'
};
} else {
// Normal processing
result = {
success: true,
message: 'Request queued',
priority: 'normal'
};
}
Transform and enrich data before responding:
// Get user submissions
const submissions = await prisma.submission.findMany({
where: { projectId: projectId },
orderBy: { createdAt: 'desc' },
take: 50
});
// Transform and aggregate
const summary = submissions.reduce((acc, sub) => {
const date = new Date(sub.createdAt).toISOString().split('T')[0];
acc[date] = (acc[date] || 0) + 1;
return acc;
}, {});
result = {
success: true,
totalSubmissions: submissions.length,
byDate: summary,
latestSubmission: submissions[0]
};
Begin with basic functionality and add complexity as needed:
Always provide clear error messages:
try {
// Your logic here
result = { success: true, data: processedData };
} catch (error) {
result = {
success: false,
error: 'Processing failed',
message: error.message,
// Don't expose sensitive details in production
};
}
Use console.log for debugging:
console.log('Processing order:', body);
// Your logic
console.log('Order processed successfully');
result = { success: true };
Logs appear in the response for debugging.
Never trust user input:
// Required fields
const required = ['name', 'email', 'message'];
const missing = required.filter(field => !body[field]);
if (missing.length > 0) {
result = {
success: false,
error: 'Missing required fields',
fields: missing
};
throw new Error('Validation failed');
}
// Email format
if (!body.email.includes('@')) {
result = { success: false, error: 'Invalid email format' };
throw new Error('Validation failed');
}
Never hardcode API keys in your code. Instead:
To ensure security and performance, some limitations apply:
