Schemas define the structure of data you want to extract from websites. They specify field names, data types, and descriptions. Schemas can be reused across multiple workflows. For example, if you need to extract store locations from 5 different websites, you can create one schema and use it for all of them.

​
Managing Schemas

Schemas can be created and managed in two ways:

In the UI

Create schemas visually using the schema builder, or select from existing templates.

Via Code

Create and manage schemas programmatically with full control over field definitions.

​
Data Types
