# Validate template field assignments

> Validates current or proposed field-to-submitter assignments without persisting any changes.
Use this to catch automapping mistakes before sending documents.




## OpenAPI

````yaml post /api/templates/{id}/validate_assignments
openapi: 3.0.3
info:
  title: SpitShake API
  version: 1.0.0
  description: >
    SpitShake is a document signing and e-signature platform. This API allows
    you to

    manage templates, send documents for signing, track submissions, and
    integrate

    document signing into your applications.


    ## Authentication


    SpitShake supports the tenant authentication methods below plus an isolated
    partner credential:


    ### API Token (Recommended)

    Pass your API token in the `X-Auth-Token` header or as `Authorization:
    Bearer <token>`.

    Generate tokens at **Settings > API** with granular scopes.


    ```

    curl -H "X-Auth-Token: YOUR_TOKEN" https://your-instance.com/api/templates

    ```


    ### OAuth 2.1 (Authorization Code + PKCE)

    For connector directories and third-party agents. Discover endpoints at

    `GET /.well-known/oauth-authorization-server`. PKCE is mandatory.


    ### Session Cookie

    Automatically set when logged into the web application. Used by the
    frontend.


    ### JWT Bearer Token (Embed API only)

    For embedded forms and builders. Generate via `POST /api/embed/token`.


    ```

    curl -H "Authorization: Bearer JWT_TOKEN"
    https://your-instance.com/api/embed/submission/123

    ```


    ### Partner Bearer Key (`/api/partner/v1` only)

    Operator-issued `spk_` keys authenticate the reseller control plane. Partner
    keys and tenant

    credentials are mutually non-acceptable.


    ## Idempotency

    Create and send operations accept an `Idempotency-Key` header. A repeated

    request with the same key and body replays the original response without

    creating a duplicate. Keys expire after 24 hours.


    ## Versioning

    Tenant API responses include an `X-API-Version: v1` header. The tenant API
    is available

    at both `/api/*` and `/api/v1/*` (explicit pin). Partner responses include

    `X-API-Version: partner-v1`, and that control plane is separately pinned at

    `/api/partner/v1/*`.


    ## Pagination


    List endpoints use cursor-based pagination:


    | Parameter | Type | Description |

    |-----------|------|-------------|

    | `limit` | integer | Items per page (1-100, default 10) |

    | `after` | integer | Return items after this ID |

    | `before` | integer | Return items before this ID |


    Response includes a `pagination` object:

    ```json

    {
      "data": [...],
      "pagination": {
        "count": 10,
        "next": 456,
        "prev": 123
      }
    }

    ```


    Use `pagination.next` as the `after` parameter to get the next page.


    ## Rate Limits


    API requests are limited to 120 requests per minute per API token.

    Partner API requests are limited to 100 requests per minute per partner key.


    ## Errors


    All errors return a JSON object with an `error` field:


    ```json

    { "error": "Not found" }

    ```


    | Status | Meaning |

    |--------|---------|

    | 400 | Bad request - invalid parameters |

    | 401 | Unauthorized - invalid or missing authentication |

    | 403 | Forbidden - insufficient permissions or plan limits exceeded |

    | 404 | Not found |

    | 422 | Unprocessable entity - validation errors |

    | 500 | Internal server error (includes `detail` field with exception
    message for debugging) |


    ## Plan Limits


    Some endpoints require specific subscription plans. If your plan doesn't
    support an endpoint,

    you'll receive a 403 response with an `upgrade_url` field.
