Strict validation (as if publishing). Returns `isValid` with warnings, or errors. A workflow is a DAG of nodes described by the `plan` object: `{ name?, nodes: [] }`. Each node has a stable string `id` and a `next` array of node ids it points to (an empty string `""` marks an unwired slot). There are three node `kind`s: - `BLOCK` — one workflow step. `{ id, kind: "BLOCK", blockId, inputs: {}, next: [] }`. `blockId` comes from `GET /v1/workflows/blocks`; `inputs` are the block's configurable inputs (discover them with `GET /v1/workflows/blocks/{blockId}`). A BLOCK has exactly one `next` slot, except the `WAIT_FOR_APPROVAL` block which has two: `[approvedTargetId, rejectedTargetId]`. - `CONDITIONAL` — branches the stream. `{ id, kind: "CONDITIONAL", conditions: [], fallbackName?, next: [] }`. Each condition is EITHER a field predicate `{ field, operator, value? }` (lead/company/AI-variable fields — discover them with `GET /v1/workflows/condition-fields`) OR a random-split branch `{ type: "RANDOM_SPLIT", percentage }` (deterministic A/B split; integer 1-100, percentages must sum to ≤ 100 across the node, the remainder falls through to the fallback). `next` has exactly `conditions.length + 1` entries: one target per matched condition (in order) then the fallback target LAST. - `KING` — dedupes/groups the stream. `{ id, kind: "KING", groupBy, orderBy, checkAnyDomain?, limit?, next: [] }`. `next` is `[leftTargetId, rightTargetId]`. The first node (the one no other node points to) should be a selector/import entry block. A plan may hold at most 60 nodes and no cycles. An empty plan (`nodes: []`) is valid for a brand-new draft. Field/entity prefixes used inside conditions: `company.`, `anyLead.`, and `webhookInput.` for webhook-triggered workflows. > **Required scope:** `WORKFLOWS_WRITE` > > **Rate limit:** 30 requests per minute ## OpenAPI ````yaml https://openapi.enginy.ai/definitions.json post /v1/workflows/validate openapi: 3.1.0 info: title: Enginy API version: 1.0.0 description: Public API for Enginy platform servers: - url: https://openapi.enginy.ai description: Configured server security: [] tags: - name: AI Variables description: >- Manage AI variables and discover the entity fields you can reference in prompts and entity requests. - name: Inbox description: >- Inbox endpoints for listing contact threads, reading thread messages, managing tags, and sending manual replies. - name: Workflows description: >- Build, validate, publish, run, and inspect advanced (graph) workflows, plus the block/condition catalog needed to author a workflow plan. paths: /v1/workflows/validate: post: tags: - Workflows summary: Validate workflow description: >- Validate a workflow `plan` payload without creating anything.
