iOS Extract API

A focused use case

Let a user submit a selected document to a controlled processing workflow and review the resulting fields on the device before export.

A practical workflow

Design the client-to-service contract first. Use an appropriate networking layer, send only the selected source, and preserve job identity through interruptions. Keep large processing jobs and long-lived secrets outside a public client bundle.

An example record contract

These fields illustrate the decisions to make before implementation. Adapt the names and required values to the receiving system; the table is not a promise of a live endpoint or a provider-specific response.

Limits worth keeping visible

An iOS client is not unrestricted access to other apps’ data. Review permissions, background behavior, and storage choices for the actual application.

Before increasing the workload

Run a small, authorized test set through the whole path, including the receiving application. Keep accepted, rejected, and incomplete outcomes distinguishable. A result should retain the context needed to explain its meaning after it leaves the extractor.
