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

• OCR Readers Worker
• AI Hub

NOTE: The Process Manager API for the AI Hub is currently only used internally by PrizmDoc Application Services (PAS). Directly using the Process Manager API for the AI Hub is not currently supported.

Available URLs

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

Request Headers

Request Body

JSON object conforming to the following:

• input - Worker specific input parameters. See worker documentation for more details.

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:

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}.
