## Inputs

### Request body

<div class="x2mdx-ref-badges">
  <span class="x2mdx-ref-badge x2mdx-ref-badge--neutral">application/json</span>
</div>

<ParamField body="choiceArguments" type="object" required>
  The arguments that are intended to be passed to the choice provided by the factory. To avoid repeating the Daml type definitions, they are specified as JSON objects. However the concrete format is given by how the choice arguments are encoded using the Daml JSON API (with the `extraArgs.context` and `extraArgs.meta` fields set to the empty object). The choice arguments are provided so that the registry can also provide choice-argument specific contracts, e.g., the configuration for a specific instrument-id.
</ParamField>

<ParamField body="excludeDebugFields" type="boolean" default="False">
  If set to true, the response will not include fields prefixed with 'debug'. Useful to save bandwidth.
</ParamField>

</ResponseField>

<ResponseField name="choiceContext" type="ChoiceContext" required>
