# Get Template

GET https://api.onepin.ai/api/v1/templates/{template_id}

Fetch a single template by ID.

Returns the template if it is visible to the caller: templates owned by the
caller's workspace are returned with the live draft definition; public/starter
templates from other workspaces are returned with the published snapshot.

Returns 404 for templates that exist but are not visible to the caller (not
owned, not public, not a starter) — same response as for a missing ID.

Dual-auth: Bearer JWT or API key (scope `templates:read`).

Reference: https://onepin.ai/docs/reference/api-reference/templates/get

## Authentication

- `Authorization` header (bearer token, required) — Clerk JWT token
- `Authorization` header (bearer token, required) — Onepin live API key (`op_live_...`). Test and public keys are reserved in Phase 1.

## Servers

- `https://api.onepin.ai` (prod, default)
- `https://dev-api.onepin.ai` (dev)

## Request

### Path parameters

- `template_id` (string, required) — Case-sensitive 8-character base62 template identifier.

### Headers

- `X-Workspace-Id` (string, optional, nullable)

## Response

### 200

Successful Response

- `data` (TemplateOut, required) — Response shape. `workspace_id` is intentionally omitted so the gallery endpoint (which returns rows from any workspace) does not leak tenant ownership IDs across tenants. `created_by` is retained as author provenance for public/starter rows. `definition` is the serialized `WorkflowDefinition` JSONB (same shape as `Workflow.definition`) — a template is a reusable workflow snapshot.
- `meta` (Meta, required)

## Errors

### 422 Unprocessable Entity Error

Validation Error

- `detail` (list of ValidationError, optional)

## Types

### TemplateOut

Response shape. `workspace_id` is intentionally omitted so the gallery endpoint (which returns rows from any workspace) does not leak tenant ownership IDs across tenants. `created_by` is retained as author provenance for public/starter rows. `definition` is the serialized `WorkflowDefinition` JSONB (same shape as `Workflow.definition`) — a template is a reusable workflow snapshot.

- `id` (string, required) — Case-sensitive 8-character base62 template identifier.
- `name` (string, required) — Display name of the template.
- `definition` (WorkflowDefinition-Output, required) — Full workflow definition (graph + execution config). Use this directly as the `definition` body when creating a workflow from scratch, or clone via `POST /templates/{id}/clone`.
- `is_starter` (boolean, required) — `true` for platform-curated starter templates. Starter templates cannot be updated or deleted.
- `is_public` (boolean, required) — `true` when this template has an active published snapshot visible in the gallery.
- `uses_count` (integer, required) — Number of times this template has been cloned into a workflow.
- `created_at` (datetime, required)
- `updated_at` (datetime, required) — Last-modified timestamp. For gallery rows this reflects the most recent publish; for own-workspace rows it reflects the most recent draft save.
- `description` (string, optional, nullable) — Optional human-readable description.
- `category` (enum, optional, nullable) — Gallery category tag, if set.
  - Allowed values: `media`, `creative`, `business`, `education`, `wellness`
- `is_favorite` (boolean, optional, default: false) — `true` when the authenticated caller has favorited this template.
- `created_by` (string, optional, nullable) — User ID of the template author.

### Meta

- `request_id` (string, required)
- `timestamp` (datetime, required)

### ValidationError

- `loc` (list of ValidationErrorLocItems, required)
- `msg` (string, required)
- `type` (string, required)
- `input` (any, optional)
- `ctx` (ValidationErrorCtx, optional)

### WorkflowDefinition-Output

- `graph` (GraphDefinition-Output, optional)
- `execution` (ExecutionDefinition, optional)

### ValidationErrorLocItems

### ValidationErrorCtx

### GraphDefinition-Output

- `nodes` (list of GraphNode, optional)
- `edges` (list of GraphEdge, optional)

### ExecutionDefinition

- `steps` (list of string, optional)
- `params` (map from string to any, optional)

### GraphNode

- `id` (string, required)
- `type` (enum, required)
  - Allowed values: `source_script`, `operator_translator`, `operator_normalizer`, `operator_generator`, `operator_phoneme_injector`, `sink_preview`, `validator_error_rate`, `validator_naturalness`, `validator_noise`, `validator_pronunciation`, `operator_pronunciation_corrector`
- `position` (NodePosition, required)
- `name` (string, optional, nullable)
- `config` (map from string to any, optional)
- `config_version` (integer, optional, default: 1)

### GraphEdge

- `id` (string, required)
- `source` (string, required)
- `sourcePort` (string, required)
- `target` (string, required)
- `targetPort` (string, required)

### NodePosition

- `x` (double, required)
- `y` (double, required)
