Your Stack. Your Rules.
Most promotions tools are locked to a single platform. If you're building on a headless or custom architecture, you're usually left stitching together scripts or building from scratch.
Deducto was built for exactly this.
Full Control
Define all your promotions in Deducto's dashboard, then get the results from our API. You own the entire customer experience.
No Vendor Lock-In
Deducto sits alongside your stack as an independent service. Swap platforms, change frontends, migrate backends, your promotions stay.
How It Works
Three steps to production-ready promotions in any stack
1
Configure in the Dashboard
Use Deducto's visual interface to build your promotion rules. Set conditions, define rewards, configure stacking behaviour, and schedule campaigns. No code required at this stage.
- Nested if/then/and/or logic for complex conditions
- Product-level and cart-level targeting
- Custom attributes for total flexibility
- Priority ordering and stacking controls
2
Integrate via API
Send your cart and customer data to Deducto's API and get back the applicable promotions and discounts. Integrate at checkout, in the cart, or anywhere in your customer journey.
- Simple REST API integration
- Coupon validation and redemption
- Works with any language or framework via standard HTTP
- Ultra-low latency designed for checkout flows
3
Launch & Iterate
Once integrated, your marketing team can create, modify, and schedule promotions independently through the dashboard. No developer involvement needed for day-to-day campaign management.
- Marketing team self-serves via the dashboard
- Scheduled campaigns with automatic start/end
- Version tracking to roll back any change
- Comprehensive logging for full visibility
For Developers
Ship Faster with a Sensible API
Deducto's REST API uses key-based authentication and is designed to get you from sign-up to production quickly. With full documentation, predictable responses, and an edge-optimized infrastructure, it adds negligible overhead to your checkout times. Promotions are verified server-side on every record call, so no client-side request can fabricate or inflate a discount.
// Send a cart
curl -X POST /v1/checkout/verify \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"cart": {
"cartItems": [...],
"currency": "USD"
"customer": {...},
"shipping": {...}
},
"couponsCodes": ["DEDUCTO-RULES"]
}'
// Get the discounts
{
"discounts": [
{ "name": "VIP 15% Off", "amount": -42.75 },
{ "name": "Free Shipping", "amount": 0 }
],
"total_discount": -42.75,
"final_total": 242.25
}
