# Feishu Card JSON 2.0

Create production-oriented Feishu Card JSON 2.0. Select the delivery surface first, build only supported interactions, keep the visual hierarchy compact, and validate the exact final payload.

## Select the delivery surface

Classify the request before choosing components:

| Surface | Output shape | Supported interaction |
|---|---|---|
| Custom bot webhook | `{"msg_type":"interactive","card":{...}}` | Static display and URL navigation only |
| Application bot / OpenAPI | Raw card object, or the enclosing API request requested by the user | URL navigation, callbacks, forms, updates |
| Callback response | `{"toast":...,"card":{"type":"raw","data":{...}}}` | Immediate toast and optional card replacement |
| CardKit/template | Template ID, version, and variables | Follow the specific CardKit API; do not pretend raw JSON supports template variables |

Never add `callback` behavior, form submission, input collection, or server-side interaction to a custom-bot webhook card. Custom bots are one-way senders. Use an application bot when the user needs callbacks or data collection.

Read [delivery-and-interaction.md](references/delivery-and-interaction.md) for webhook signing, callbacks, updates, streaming, and payload envelopes.

## Gather the minimum brief

Infer safe defaults when possible. Identify:

- one primary purpose and audience;
- delivery surface;
- title, summary, content sections, severity/status;
- primary and secondary actions;

Build a scroll-scrubbed hero from one or two REAL photos plus an idea — or from the idea alone. Scrolling drives a subject through a transformation (bare yard → finished pool, empty room → staged interior, raw stock → machined part, before → after). Uses kie.ai: GPT 5.6 Sol writes the storyboard, GPT Image 2 renders keyframe stills so the client's ACTUAL property stays recognisable (and draws the opening frame when there is no photo), Kling 3.0 first/last-frame tweens the motion, and ffmpeg cuts drop-in scrub frames plus config.js. Use whenever someone wants a scroll-driven build/progress/befo
