From Chaos to Capsules: Scalable Supplement Fulfillment via the OK Capsule API
I’ve worked with teams launching everything from longevity stacks to private label GLP-1 support vitamins, and they all ask the same thing:
"How do we scale this without building a fulfillment operation from scratch?"
That’s exactly what we designed the OK Capsule API to solve.
It’s not just about automating shipping — it’s about providing nutraceutical personalization and fulfillment as a service. That includes everything from compliant manufacturing in cGMP-certified facilities, to packet-level customization, to direct-to-consumer shipping — all controllable via one clean, well-documented API.
Fulfillment, Fully Integrated
Fulfillment is often a blocker for personalized supplement brands. Why? Because most APIs assume you’re shipping static SKUs. But personalized wellness doesn’t work that way.
The OK Capsule API is different:
Personalized daily packets? ✅
Variable serving sizes? ✅
Reusable or one-off consumers? ✅
Custom-branded pouch and dispenser labeling? ✅
Multi-dispenser orders in one call? ✅
It plugs directly into your onboarding flow, product logic, or practitioner UI — so fulfillment disappears into the background.
Submit a Full Order in One Call
Here’s what a real-world, multi-dispenser order looks like:
bash
CopyEdit
POST /orders
Content-Type: application/json
json
CopyEdit
{
"consumer": {
"first_name": "Bart",
"last_name": "Simpson",
"email": "user@email.com",
"phone_number": "+18885551212"
},
"shipping_address": {
"addressee": "Lisa Simpson",
"address1": "742 Evergreen Terrace",
"city": "Springfield",
"province_name": "Ohio",
"postal_code": "45501",
"country_name": "United States"
},
"order_lines": [
{
"pouches": [
{
"custom_label": "Daily Essentials",
"contents": [
{
"client_product_id": "d290f1ee-6c54-4b01-90e6-d701748f0851",
"serving_size": 2
},
{
"client_product_id": "d290f1ee-6c54-4b01-90e6-d701748f0851"
}
]
}
]
},
{
"pouches": [
{
"custom_label": "GLP-1 Support Protocol"
},
{
"pack_id": "d290f1ee-6c54-4b01-90e6-d701748f0851"
}
]
}
]
}
🧠 Note: Each order_line equals one dispenser box. Multiple order lines = multiple boxes in one shipment. Use it to split daily packets, onboarding protocols, or time-specific regimens.
Lifecycle Management: Track, Cancel, Follow Every Step
You can monitor each order as it moves through the pipeline: received, processing, fulfilled, and more.
To view fulfillment activity tied to an order, use:
bash
CopyEdit
GET /orders/{order_id}/fulfillments
This returns detailed records for each fulfillment event, including status, timestamps, and tracking data when available — ideal for real-time order status pages or proactive customer support.
If you need to cancel an order before it enters production:
bash
CopyEdit
PUT /orders/{order_id}
Content-Type: application/json
json
CopyEdit
{
"status": "Canceled"
}
The API enforces safe state transitions and integrates cleanly into error handling or customer service flows.
