Preview changes from this workspace into the other workspace along a direct fork edge. Requires Admin access to both workspaces. The plan lists workflows to create, replace, or archive; replacements overwrite target drafts with the source deployment. Proposed mappings are not saved. Dependent choices use source workflow, block, and field IDs. Billing-enabled deployments require Enterprise. Billing-disabled deployments require forking to be enabled by deployment feature configuration, such as FORKING_ENABLED. Workspace API keys return 403; use a personal API key or scoped OAuth token.
OAuth scope: api:write.
/api/v2/workspaces/{workspaceId}/fork/push/previewSend a personal or workspace API key in X-API-Key. See key types and access; operations that reject workspace keys say so in their description.
In: header
Request examples use an API key. For OAuth, replace the X-API-Key header with Authorization: Bearer YOUR_ACCESS_TOKEN.
