# Run Actor synchronously without input

`GET /v2/actors/{actorId}/run-sync`

Runs a specific Actor and returns a key-value store record. The response contains the
record stored under the `OUTPUT` key in the run's default key-value store.
This is a legacy approach that has been replaced by the Actor
[output object](https://docs.apify.com/platform/actors/development/actor-definition/output-schema#output-object-definition);
the record may not exist, in which case the response contains no data. Use the
`outputRecordKey` query parameter to return a different record.
The run must finish in 300<!-- MAX_ACTOR_JOB_SYNC_WAIT_SECS --> seconds
otherwise the API endpoint returns a timeout error.
The Actor is not passed any input.

Beware that it might be impossible to maintain an idle HTTP connection for a
long period of time,
due to client timeout or network conditions. Make sure your HTTP client is
configured to have a long enough connection timeout.
If the connection breaks, you will not receive any information about the run
and its status.

To run the Actor asynchronously, use the [Run
Actor](#/reference/actors/run-collection/run-actor) API endpoint instead.
