API · Validation Tests PUT `/api/v1/validation-tests/{validationTestUuid}` Requires the GV.APIContributor application role, or a higher role (Owner > Contributor > Reader). Operation ID · update\_validation\_test ## Request example ```bash theme={null} curl --request PUT \ --url 'https://api.generalvalidation.com/api/v1/validation-tests/99999999-9999-4999-8999-999999999999' \ --header 'Accept: application/json' \ --header 'Authorization: Bearer ' \ --header 'If-Match: ""' \ --header 'Content-Type: application/json' \ --data '{ "comment": "Allow one cent of aggregate rounding variance.", "functionCode": "SUM", "operator": "=", "sourceField": "amount", "targetField": "amount", "threshold": "0.01" }' ``` ## Authentication and access * **Required role:** GV.APIContributor * **Data classification:** metadata * **Side effects:** configurationWrite Use an authentication scheme declared below. Ordinary workloads use application tokens; signed-in users use delegated tokens and Organization membership. Activation and invitation acceptance require a person, and execution callbacks require their registered identity. * Microsoft Entra delegated user token * Microsoft Entra application token ## Parameters ### validationTestUuid path Required Opaque Validation Test UUID. `string (uuid)` Opaque Validation Test UUID. ### If-Match header Required Exact strong ETag from the current Validation Test.

Retrieve the deployed, authenticated OpenAPI document for the exact response body schemas and examples. The API also provides an authenticated Swagger UI; opening it in a browser does not automatically attach a bearer token. Error responses use `application/problem+json`. The response's stable `code` and `type` map to the [error-code reference](/errors). ### 200 Validation Test updated. #### Headers * **ETag:** `string` ### 401 A valid Microsoft Entra bearer token is required. ### 402 The organization entitlement does not permit this mutation. ### 403 The authenticated principal does not have the required role. ### 404 The resource does not exist in this tenant. ### 409 The operation conflicts with current resource or Azure state. ### 412 If-Match did not match the resource's current strong ETag. ### 422 The request is syntactically valid but semantically invalid. ### 428 The exact current ETag is required in If-Match. ### 429 The bounded application request rate was exceeded. #### Headers * **Retry-After:** Seconds to wait before retrying. `integer`minimum: 1 ### 503 A required dependency is temporarily unavailable. #### Headers * **Retry-After:** Seconds to wait before retrying. `integer`minimum: 1
