Generate Seedance videos with the Vancine Doubao API using polling
Ready for 3.0Ready for 3.0. This template uses no nodes that n8n 3.0 removes. No removed nodes, versions or helpers found. Static check, last run 2026-10-19.
What this workflow does
This workflow has 16 nodes and runs manually, when you click “Execute workflow”. It uses only n8n's built-in nodes.
How it runs
Trigger: Manually, when you click “Execute workflow”.
- setFields (Edit Fields (Set)): sets 6 fields: model, prompt, size…
- submitTask (HTTP Request): calls an HTTP API (POST)
- saveTaskId (Edit Fields (Set)): sets 5 fields: task_id, base_url, intervalSeconds…
- Wait: pauses before continuing
- pollTask (HTTP Request): calls an HTTP API (GET)
- carryState (Edit Fields (Set)): sets 5 fields: task_id, poll_index, maxPolls…
- Merge: merges the data from its input branches
- mergeState (Code): runs custom JavaScript code
- If: checks a condition and branches into true / false
- outputResult (Edit Fields (Set)): sets 2 fields: result_url, task_id
…plus 5 more steps. See the full node list below.
Before you upgrade to n8n 3.0
Nothing in this workflow is removed in n8n 3.0, so it should import and run after the upgrade.
