    In This Topic

    Introduction

    The Process Manager implements the following public API to allow users to create work processes which will be handled by worker instances. Each type of worker will require specific input parameters and return their own output data. See the documentation for those workers for additional details:

    Workers

    Available URLs

    URL Description
    POST /v1/processes/{processType}
    GET /v1/processes/{processType}/{processId}

    POST /v1/processes/{processType}

    Creates and starts a new process.

    NOTE: There is a deprecated alias for this route: POST /v4/processes/{processType}.

    Request

    URL Parameters

    Parameter Description
    {processType} The type of process desired. See worker documentation for more details.

    Request Headers

    Name Description
    Content-Type Must be application/json

    Request Body

    JSON object conforming to the following:

    Successful Response

    Response body

    JSON object with the following properties:

    • input (Object) A copy of the request body input object.
    • processId (String) The id of the new OCR process.
    • expirationDateTime (String) The date and time (in ISO 8601 Extended Format) when the OCR process will be deleted.
    • state (String) The current state of the OCR process running on the server. The response will always be "processing".

    Error Responses

    Error response will have the http status code set to one of following values and the JSON object will contain a property errorCode indicating the type of error:

    Status Code JSON errorCode Description
    480 "MissingInput" A required input value was not provided. See errorDetails in the response body.
    480 "InvalidInput" An invalid input value was used. See errorDetails in the response body.
    480 "UnrecognizedInput" An unrecognized JSON property was provided. See errorDetails in the response body.
    580 "InternalError" The server encountered an internal error when handling the request.

    GET /v1/processes/{processType}/{processId}

    Gets the state and result of an existing process created by POST /v1/processes/(processType). Requests can be sent to this URL repeatedly while state is "processing".

    When state is "complete" the response will include a result object which contains the output from the worker process. See worker documentation for more details.

    If the process encountered an error, the state property will be set to "error" and the errorCode property will contain an error code string.

    NOTE: There is a deprecated alias for this route: GET /v4/processes/{processType}/{processId}.

    Successful Response

    Response body

    JSON object with the following properties:
