APIs That Connect Everything You Run

Your business runs on more than one system: a CRM, an e-commerce platform, a booking tool, an accounting package, maybe a custom internal tool. None of that data does much good sitting in separate silos. j3mweb builds APIs and integrations that move your data where it needs to go, automatically, so your systems work together instead of around each other.

Whether you need to push orders into your accounting software, sync customer records between platforms, or expose your own data to a partner or app, we build the connection and make sure it keeps working.

What's Included

• Custom API development, REST and other formats, built around your data
• Integrations between the platforms and tools you already use
• Automated data pushes and syncs to any destination: a database, another platform, a partner's system, or a data warehouse
• Authentication and access control so only the right systems can reach your data
• Error handling and monitoring so failed syncs get caught and fixed, not lost
• Documentation so your team, or a future developer, understands exactly how it works

Popular Integrations We Build

Not sure where to start? These are the integrations business owners ask for most. Each one solves a specific, everyday problem — here's what each does and roughly how it works, in plain terms.

Google Maps

An interactive map embedded right on your site, showing your business location, with directions and often address autocomplete on your contact or checkout forms. It works by connecting to Google's map service with an API key, so the map on your page is always live and accurate — no static image to update by hand. It's one of the most requested additions because it builds instant trust and helps local customers find you.

Example: embedding the map

<div id="map" style="height: 400px;"></div>
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY"></script>
<script>
  const map = new google.maps.Map(document.getElementById("map"), {
    center: { lat: 32.7767, lng: -96.7970 },
    zoom: 14,
  });
  new google.maps.Marker({
    position: { lat: 32.7767, lng: -96.7970 },
    map: map,
  });
</script>

Product Feeds for Google Shopping & Facebook/Instagram Shop

If you sell products, this connects your catalog to where shoppers are already browsing. We package your product data — names, prices, photos, availability — into the format Google Merchant Center and Meta Commerce Manager expect, and submit it so your items appear in Google Shopping results and the Shop tabs on Facebook and Instagram. It updates on a schedule, so you manage your catalog in one place and it shows up everywhere automatically.

Example: one product in the feed

<item>
  <g:id>SKU-1001</g:id>
  <g:title>Wireless Mouse</g:title>
  <g:price>19.99 USD</g:price>
  <g:availability>in stock</g:availability>
  <g:link>https://example.com/products/wireless-mouse</g:link>
  <g:image_link>https://example.com/images/wireless-mouse.jpg</g:image_link>
</item>

Online Payments (Stripe, PayPal)

Letting customers pay by card or PayPal without leaving your site. The payment provider handles the sensitive card details directly — your website never stores or even sees the card number — so you get a modern checkout experience without taking on the compliance burden of handling card data yourself.

Example: creating a charge (Stripe)

$stripe = new \Stripe\StripeClient($secretKey);

$paymentIntent = $stripe->paymentIntents->create([
    'amount' => 2000, // $20.00, in cents
    'currency' => 'usd',
    'automatic_payment_methods' => ['enabled' => true],
]);

echo $paymentIntent->client_secret;

SMS Notifications (Twilio)

Automated text messages for appointment reminders, order updates, or time-sensitive alerts. Your system sends the message and a phone number to the SMS provider, which delivers it and confirms whether it went through. Text messages get read far faster than email, which makes this a strong option for anything urgent or time-sensitive.

Example: sending a reminder text

use Twilio\Rest\Client;

$twilio = new Client($accountSid, $authToken);

$twilio->messages->create('+12145551234', [
    'from' => '+18885551234',
    'body' => 'Your appointment is confirmed for 3:00 PM tomorrow.',
]);

Transactional Email (SendGrid, Mailgun)

The receipts, invoices, password resets, and confirmations your business sends automatically. These are different from marketing emails — they need to actually land in the inbox, every time. A dedicated email delivery service handles that reliability and keeps track of what was delivered, instead of relying on a basic server email function that spam filters increasingly distrust.

Example: sending an invoice email

$email = new \SendGrid\Mail\Mail();
$email->setFrom('billing@example.com', 'Example Co.');
$email->addTo('customer@example.com');
$email->setSubject('Your Invoice #1042');
$email->addContent('text/html', '<p>Your invoice is attached.</p>');

$sendgrid = new \SendGrid($apiKey);
$sendgrid->send($email);

AI Chat Assistants (OpenAI, Claude)

A chat widget on your site that can answer common customer questions instantly, any time of day. A visitor's message is sent to an AI service along with context about your business, and the AI's response appears right in the chat window. It's a fast way to handle repetitive questions and capture leads outside business hours, without staffing a live chat.

Example: asking the AI a question

$response = $httpClient->post('https://api.openai.com/v1/chat/completions', [
    'headers' => ['Authorization' => "Bearer {$apiKey}"],
    'json' => [
        'model' => 'gpt-4o-mini',
        'messages' => [
            ['role' => 'system', 'content' => 'You are a helpful assistant for Acme Co.'],
            ['role' => 'user', 'content' => $customerMessage],
        ],
    ],
]);

Why It Matters

Manually exporting and re-entering data between systems wastes time and introduces mistakes. A properly built API or integration moves data automatically and consistently, so the numbers in one system actually match the numbers in another, and your team spends time running the business instead of copying spreadsheets.

Our Process

1. Discovery — We map out which systems need to talk to each other and what data actually needs to move.
2. Design — We design the API or integration around your existing systems, not the other way around.
3. Build & Test — We build and test the connection thoroughly before it touches real data.
4. Monitor & Support — We monitor the integration after launch and fix issues before they become data problems.

Who This Is For

Businesses juggling multiple platforms that don't talk to each other, needing to expose their own data to a partner or app, or tired of manually moving data between systems.
