Cloud Document AI API Connector Overview

The Workflows connector defines the built-in
functions that can be used to access other Google Cloud products within a
workflow.
This page provides an overview of the individual connector.
There is no need to import or load connector libraries in a workflow—connectors
work out of the box when used in a call step.
Cloud Document AI API
Service to parse structured information from unstructured or semi-structured documents using state-of-the-art Google AI such as natural language, computer vision, translation, and AutoML.
To learn more, see the Cloud Document AI API documentation.
Cloud Document AI connector sample
Module: googleapis.documentai.v1.projects.locations
| Functions |
fetchProcessorTypes |
Fetches processor types. Note that we do not use ListProcessorTypes here
because it is not paginated. |
get |
Gets information about a location. |
list |
Lists information about the supported locations for this service. |
Module: googleapis.documentai.v1.projects.locations.operations
| Functions |
cancel |
Starts asynchronous cancellation on a long-running operation. The server
makes a best effort to cancel the operation, but success is not
guaranteed. If the server doesn't support this method, it returns
google.rpc.Code.UNIMPLEMENTED. Clients can use Operations.GetOperation
or other methods to check whether the cancellation succeeded or whether
the operation completed despite cancellation. On successful
cancellation, the operation is not deleted; instead, it becomes an
operation with an Operation.error value with a google.rpc.Status.code of
1, corresponding to Code.CANCELLED. |
get |
Gets the latest state of a long-running operation. Clients can use this
method to poll the operation result at intervals as recommended by the
API service. |
list |
Lists operations that match the specified filter in the request. If the
server doesn't support this method, it returns UNIMPLEMENTED. NOTE:
the name binding allows API services to override the binding to use
different resource name schemes, such as users/*/operations. To
override the binding, API services can add a binding such as
"/v1/{name=users/*}/operations" to their service configuration. For
backwards compatibility, the default name includes the operations
collection id, however overriding users must ensure the name binding is
the parent resource, without the operations collection id. |

create |
Creates a processor from the type processor that the user chose. The
processor will be at "ENABLED" state by default after its creation. |
delete |
Deletes the processor, unloads all deployed model artifacts if it was
enabled and then deletes all artifacts associated with this processor. |
disable |
Disables a processor |
enable |
Enables a processor |
get |

ProcessDocument and BatchProcessDocuments. |

| Functions |
batchProcess |
LRO endpoint to batch process many documents. The output is written to
Cloud Storage as JSON in the [Document] format. |

will be deleted. |
