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.

Direct answer

The decision this page is for.

Last verified:

A digital comic download charges first, generates once, reviews the output, then releases a protected file. It is the lowest-operations commerce pilot because there is no print or shipping, but status, retries, and refunds are still required.

Customer scenario

Deliver an approved comic without a physical fulfillment step.

The flow focuses on payment, generation, customer review, one revision boundary, and secure digital-file access.

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.

  1. 01Commerce platform

    Confirm payment

    Start the expensive generation only after the order reaches the merchant's approved paid state.

  2. 02App backend

    Create the job

    Use an idempotency record so webhook retries cannot create duplicate billable generations.

  3. 03Review queue

    Inspect the output

    Validate names, captions, continuity, safety, and the purchased panel count.

  4. 04Delivery service

    Package the files

    Store approved images or a rendered PDF under a private, expiring download route.

  5. 05Customer account

    Release and measure

    Notify the buyer, record download access, and retain a visible correction or refund path.

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.

Questions

Direct answers before you integrate.

01When is the download URL created?
After the job is approved, from files you stored privately. Do not email raw temporary API URLs.
02What if generation fails after payment?
Show a failed state, retry with idempotency, or refund. A successful HTTP create is not the same as an approved deliverable.
03Why start here instead of print?
You validate willingness to pay without inventory, prepress, or carriers, while still exercising the async generation contract.
