After you submit the task to us, you should receive in the response a ‘taskId’ if it’s successful. Please read errorCode: full list of errors if you didn’t receive the task id.
Example Response
{
"errorId": 0,
"errorCode": "",
"errorDescription": "",
"taskId": "61138bb6-19fb-11ec-a9c8-0242ac110006"
}
Getting Results
After you have the taskId, you need to submit the taskId to retrieve the solution. Response structure is explained in getTaskResult.
Depending on the system load, you will get the results within the interval of 1s
to 10s
