Query completions list (blocking call) Deprecated: please use `GetCompletions` instead. Subscribe to command completion events. Notice: This endpoint should be used for small results set. When number of results exceeded node configuration limit (`http-list-max-elements-limit`) there will be an error (`413 Content Too Large`) returned. Increasing this limit may lead to performance issues and high memory consumption.

</ParamField>

### Request body

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

<ParamField body="userId" type="string">
  Only completions of commands submitted with the same user\_id will be visible in the stream. Must be a valid UserIdString (as described in `value.proto`). Required unless authentication is used with a user token. In that case, the token's user-id will be used for the request's user\_id. Optional
</ParamField>

<ParamField body="parties" type="string[]" required>
  Non-empty list of parties whose data should be included. The stream shows only completions of commands for which at least one of the `act_as` parties is in the given set of parties. Must be a valid PartyIdString (as described in `value.proto`). Required: must be non-empty
</ParamField>

<ParamField body="beginExclusive" type="number">
  OpenAPI type: `integer (int64)`.

  This optional field indicates the minimum offset for completions. This can be used to resume an earlier completion stream. If not set the ledger uses the ledger begin offset instead. If specified, it must be a valid absolute offset (positive integer) or zero (ledger begin offset). If the ledger has been pruned, this parameter must be specified and greater than the pruning offset.
