# Updating an existing Estimate Scenario

This endpoint returns structured Estimate Scenario objects.
As with all Kantata OX API endpoints, the returned data will be referenced in sorted order in the results array
and will be indexed by ID in the estimate_scenarios top-level JSON key.
Please see our Response Format section for more information.

Endpoint: PUT /estimate_scenarios/{id}
Version: 1.0.0

## Path parameters:

- estimate_scenario_resources (EstimateScenarioResource) - The Estimate Scenario Resources of the Estimate Scenario.
- external_references (ExternalReference) - Includes references to external integrations for this object.
- rate_card (RateCard) - The rate card being used for the estimate scenario.

## Request fields (application/json):

  - `estimate_scenario` (object)

  - `estimate_scenario.budget_in_cents` (integer)
    The planned budget for the scenario.

  - `estimate_scenario.name` (string)

Kantata OX (for example, to connect a Jira issue to a Kantata OX Project).

  - `estimate_scenario.external_reference.service_name` (string, required)
    The provider name of the integration. If you are adding multiple external references to the same object, the service_name must be unique.

  - `estimate_scenario.external_reference.service_model` (string, required)
    The object type of the external object this external reference belongs to.

  - `estimate_scenario.external_reference.service_model_ref` (string, required)
    The object ID of the external object this external reference belongs to.

  - `estimate_scenario.external_reference.status` (string)
    The status of the integration. Options are successful, pending,  or failed.

  - `estimate_scenario.external_reference.external_message` (string)
    The message on the external object.

  - `estimate_scenario.external_reference.external_link` (string)
    The link to the external object.

  - `estimate_scenario.external_reference.external_status` (string)
    The status of the external object in the external system.

  - `estimate_scenario.external_reference.locked` (boolean)
    Whether the subject is locked.
