Cancel a long running operation

Cancels a long running operation (LRO)

Change the default processor version

A processor's default version specifies the version that is used to process documents when you don't specify a specific version. When you create a processor, the initial default version is the latest version in the stable channel. If you change the default version, incoming requests are processed using the newly selected version. If you change the default version while the processor is in the middle of a request, the request will continue to use the previously selected version.

Delete a processor version

After creating a new processor version, you can delete it if you have no further use for the processor version. Note: You cannot delete pretrained processor versions or the current default version.

Deploy a processor version

After creating a new processor version, you will need to deploy it before you can process documents with this version. Note: You cannot change the deployment status for pretrained processor versions or the current default version.

Poll a long-running operation

To poll an LRO, repeatedly call the get_long_running_operation method until the operation finishes. Use a backoff between each poll request, such as 10 seconds.

Process a document using a Form Parser processor

Sends an online processing request to a Form Parser processor and parses the response. Extracts and prints form fields and tables.

Send a batch process documents request

Sends a batch (asynchronous) processing request to a processor.

Send a batch processing request to a processor version

Starting with the v1 API version of Document AI you can create multiple versions of a processor resource. After creating a processor version you can send processing requests to that specific processor version. If you do not specify a processor version, the default version will be used.

Send an online processing request

Online (synchronous) requests let send a single document for processing.
