## 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>

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

<ResponseField name="factoryId" type="string" required>
  The contract ID of the contract implementing the factory interface.
</ResponseField>

<ResponseField name="transferKind" type="string" required>
  The kind of transfer workflow that will be used: \* `offer`: offer a transfer to the receiver and only transfer if they accept \* `direct`: transfer directly to the receiver without asking them for approval. Only chosen if the receiver has pre-approved direct transfers. \* `self`: a self-transfer where the sender and receiver are the same party. No approval is required, and the transfer is typically immediate.

  Allowed values: <code>self</code>, <code>direct</code>, <code>offer</code>.
</ResponseField>

<ResponseField name="choiceContext" type="ChoiceContext" required>
  The context required to exercise a choice on a contract via an interface. Used to retrieve additional reference data that is passed in via disclosed contracts, which are in turn referred to via their contract ID in the `choiceContextData`.

  <Expandable title="child attributes">
    <ResponseField name="choiceContextData" type="object" required>
      The additional data to use when exercising the choice.
    </ResponseField>

    <ResponseField name="disclosedContracts" type="DisclosedContract[]" required>
      The contracts that are required to be disclosed to the participant node for exercising the choice.

        <ResponseField name="synchronizerId" type="string" required>
          The synchronizer to which the contract is currently assigned. If the contract is in the process of being reassigned, then a "409" response is returned.
        </ResponseField>

        <ResponseField name="debugPackageName" type="string">
          The name of the Daml package that was used to create the contract. Use this data only if you trust the provider, as it might not match the data in the `createdEventBlob`.
        </ResponseField>

        <ResponseField name="debugPayload" type="object">
          The contract arguments that were used to create the contract. Use this data only if you trust the provider, as it might not match the data in the `createdEventBlob`.
        </ResponseField>

        <ResponseField name="debugCreatedAt" type="string (date-time)">
          The ledger effective time at which the contract was created. Use this data only if you trust the provider, as it might not match the data in the `createdEventBlob`.
