# Extract ZATCA E-Invoice Data

Finance teams use this recipe to extract ZATCA E-Invoice fields into structured JSON for accounts receivable, accounts payable, tax, and ERP workflows.

## APIs Used

Document Extraction (1 credit per page)

## Prerequisites

You need an Iteration Layer API key. Get one at [platform.iterationlayer.com](https://platform.iterationlayer.com) during the 7-day trial.

For full integration guidance (SDKs, auth, MCP, error handling), see the [Iteration Layer Integration Guide](https://iterationlayer.com/SKILL.md).
