Digital delivery workflow
Turn a paid brief into a protected comic download.
A digital comic product accepts a bounded customer brief, creates the final comic after payment, and releases downloadable assets only after generation and approval succeed.
Removing print and shipping makes this the simplest commerce validation path, but the product still needs status, review, secure delivery, correction, and refund rules.

}Output evidence
Inspect the visual result and the machine-readable state.
The visual is evidence of the output category. The JSON is what lets an application correlate the generation, render a preview, store assets, and continue the workflow.
Digital fulfillment
A download becomes available only after the job is approved.
The storefront can sell a familiar digital product while the backend treats generation, approval, and file release as separate observable states.
- 01Commerce platform
Confirm payment
Start the expensive generation only after the order reaches the merchant's approved paid state.
- 02App backend
Create the job
Use an idempotency record so webhook retries cannot create duplicate billable generations.
- 03Review queue
Inspect the output
Validate names, captions, continuity, safety, and the purchased panel count.
- 04Delivery service
Package the files
Store approved images or a rendered PDF under a private, expiring download route.
- 05Customer account
Release and measure
Notify the buyer, record download access, and retain a visible correction or refund path.
Capability and boundary facts
Facts an integration can verify.
Last verified:
- Fulfillment
- Protected page image or PDF download
- Generation trigger
- Verified paid order
- Status
- Queued, processing, review, ready, or failed
- Access
- Short-lived or authenticated download URL
- Recovery
- Retry, correction, and refund paths
Good fit
Use it when
- Testing willingness to pay without print logistics
- Last-minute gifts and event downloads
- Stores that can review output before release
Wrong fit
Do not use it for
- Emailing raw temporary API URLs
- Promising instant output when generation is asynchronous
- Unlimited regeneration without a cost boundary
Production limits
Plan for the boundaries.
- 01A successful API response is not the same as an approved customer deliverable.
- 02Do not publish permanent public asset URLs containing customer-specific output.
- 03Define download duration, file formats, revision allowance, and refund handling before checkout.
- 04Generation is asynchronous; production interfaces must handle processing and failure states.
- 05Outputs should be reviewed against product, brand, safety, and print requirements before delivery.
- 06You must have the rights to prompts, photos, scripts, and reference assets submitted to the API.
Next step
