FAQs

How does Voiden handle API documentation and testing?

Voiden unifies API documentation and testing by allowing requests, docs, and explanations to live side-by-side in plain Markdown files. These files are executable, meaning you can run API requests directly from the documentation, eliminating the need to switch between tools.

What does 'Git-native' mean for Voiden users?

Being Git-native means Voiden uses Git as its storage layer. All API definitions, tests, and documentation are stored as pure Markdown files in your Git repository. This enables version control, diffing, reviewing, and branching of your API work just like code, without proprietary formats or export/import steps.

Can Voiden integrate with existing API specifications like OpenAPI or Postman collections?

Yes, Voiden supports importing existing API specifications. It offers enhanced Postman Import for both v2.0 and v2.1 collections, and can import OpenAPI specs to auto-generate .void files, facilitating smooth migration of your existing API assets into the Voiden workflow.
