Workflow nodes

Add a branch

Add a branch and a child node under an existing Branch or Experiment node. Returns the created child node plus the latest workflow.

  • Adding a branch to a BranchNode creates one AudienceFilter child node.
  • Adding a branch to an ExperimentBranchNode creates one VariantNode child node.

This endpoint does not accept node configuration fields; update the child node with POST /v1/workflows/{workflowId}/nodes/{nodeId} after creation. Public workflows are limited to 300 nodes, and this endpoint adds 1 node.

post/v1/workflows/{workflowId}/nodes/{nodeId}/add-branch

Request body

expectedRevisionIdstring nullable required

The workflow revision token returned by the latest workflow read or mutation. Older workflows may return null before their first revision-aware mutation; pass null back as expectedRevisionId in that case. If the token is stale, the API returns a 409 Conflict error.

Response

Branch added.
