Seedance 2.0 API workflow

Seedance 2.0 API Workflow for Batch Video

API generation is useful only after the creative pattern is stable. Use the website demo to find the prompt, reference image, duration, and aspect ratio that work, then move repeated variants into a queue so you can produce clips without manually babysitting every render.

Connect to the current customer API

Sign in to the developer console after a successful purchase to create a key. Keep it on your server. Read the REST API documentation for request fields and API pricing for the shared credit balance.

Submit one job per POST to /api/v1/generations with a Bearer key and a unique Idempotency-Key. Poll /api/v1/generations/{id} for status. Reuse the same idempotency key when retrying the same request after a network failure; a changed request needs a new key. Keep your queue within the documented rate limits.

For references, create an upload draft, upload its image or video files, and pass that draft ID with the generation request. Submit within the 24-hour reference lifetime. A batch queue is your application workflow, not a separate bulk endpoint.

When to use API batching

Use batching when you need many similar outputs: product color variants, ad hooks, UGC-style scene tests, localization, or thumbnail motion studies. If the prompt still changes heavily after every render, stay with the prompt playbook until the recipe is repeatable.

Batch pipeline overview

  1. Create a shot table with one row per output: shot ID, prompt, aspect ratio, duration, reference image, and status.
  2. Render three manual samples first. Do not batch a prompt that has not produced at least one usable result.
  3. Submit small groups before large queues. Ten reliable jobs are more useful than one hundred unknown failures.
  4. Retry only failed or off-brief shots. Keep successful prompt rows unchanged so the batch stays comparable.
  5. Archive output URL, cost, render time, and notes. This makes later ad tests and client revisions faster.

Prompt row example

shot_id: watch_hook_03
prompt: 6-second macro product hook. Silver smartwatch rotates on wet slate, screen wakes with soft blue glow, slow clockwise orbit, shallow depth of field, no text.
aspect_ratio: 9:16
duration: 6
reference_image: watch_front_silver.png
status: ready

Quality control before download

Check every batch against the same criteria: subject identity, motion direction, camera behavior, brand safety, frame composition, and whether the first second earns attention. For ecommerce and ad clips, the product should be recognizable immediately. For character or story clips, the viewer should understand the action without reading the prompt.

If outputs are inconsistent, reduce variables. Use one product image, one background style, one camera movement, and one duration. Once the first batch performs, create a second batch for variants. Internal links such as Seedance 2.0 pricing and the comparison hub can help buyers choose the right workflow before committing to larger queues.

Validate before you batch

Create a short manual sample, save the exact prompt, then scale the same recipe into a queue.
