Build with PrintKK API
Start from signature authentication, then implement image upload, design creation, order creation, and order payment with REST endpoints.
Core API Capabilities
Focus on the key production workflow from assets to payment, based on the documented endpoint groups.
Signature and Authentication
Use the Signature and Auth specifications to secure each request and control access to your API operations.
Upload Images
Upload design assets through image endpoints and prepare files for downstream design generation.
Create Designs
Create design data with the design endpoints and organize required parameters for production-ready output.
Create and Pay Orders
Submit order payloads and complete payment through order endpoints to close the transaction flow.
API Integration Flow
From the very first authenticated call to a paid order, this four-stage path mirrors how our APIs are grouped in the documentation: secure access, image assets, printable designs, then checkout and payment. Treat each stage as a checkpoint so your backend stays predictable and easy to debug.
Configure signature and authentication
Read the Signature and Authentication chapters, issue or import the credentials your environment needs, and implement signing exactly as specified. Send a few low-risk test requests and confirm you receive successful responses before touching uploads--when auth is solid, later errors almost always point to payload shape instead of mystery 401s.
Upload the images your products need
Use the image endpoints to upload logos, artwork, or other files your integration requires. Store each identifier returned in the API response so you can pass those values into subsequent design requests in the same shape as the request examples.
Create and persist design records
Call the design endpoints to create design records that combine products, placements, and the image references from the previous step. Keep the returned design identifiers in your system so order payloads can reference them as described in the Order section of the documentation.
Submit the order and finish payment
Submit orders through the order endpoints using the design identifiers you stored. Complete payment by following the steps documented for the payment-related endpoints. Responses, status codes, and error bodies in the documentation are authoritative--do not rely on behavior that is not described there.
Beyond the core integration path
The official API documentation also groups Product, General, FAQ, and Changelog alongside Authentication, Image, Design, and Order. Use these sections when you need catalog data, shared utilities, or release history that the core flow does not cover by itself.
-
Product
The Product endpoints describe how to query catalog items, variants, and options that pair with designs and orders. Consult them when you must resolve product IDs or attributes before building a payload.
-
General
The General section covers utilities and cross-cutting requests that sit beside image, design, and order calls. Check the reference when you need helper operations documented there.
-
FAQ and Changelog
Read the FAQ for common integration questions and use the Changelog to track API updates, additions, and any breaking changes over time.
Common API Use Cases
Typical implementation patterns built on image, design, and order capabilities.
Automated Design Pipeline
Upload images in batches and generate designs programmatically to accelerate content production.
Order Submission Service
Build a backend service that converts checkout data into standardized order requests.
Payment Completion Workflow
Connect order creation and payment endpoints into one controlled transaction sequence with clear status handling.
Resources for Teams
Use documentation and support channels to accelerate development and rollout.
Developer Documentation
Review endpoint groups, authentication details, and payload examples for image, design, and order operations.

API FAQ
What should we implement first?
Start with Signature and Authentication so every subsequent image, design, and order request is verifiable and secure.
Which core operations are supported?
The core documented operations are image upload, design creation, order creation, and order payment.
How should we structure the call sequence?
Use a linear flow: authenticate requests, upload images, create designs, create orders, then complete payment.
Where can we find request details?
See the API documentation for endpoint parameters, request examples, and section-specific implementation notes.
