# microsoft-kiota-serialization-json — Core abstractions for kiota generated libraries in Python

License: permissive · Maintenance: active · Downloads: 14.3M/mo

## What it is and what it does

This package provides JSON serialization and deserialization support for API clients generated by Microsoft Kiota, a code generator that creates strongly-typed API client libraries from OpenAPI specifications. It handles the conversion of JSON payloads received from API endpoints into Python objects and vice versa, integrating with the Kiota abstractions layer. The package is designed as a companion to Kiota-generated projects rather than as a standalone JSON library—it implements the serialization contract expected by Kiota's generated code.

The package depends on microsoft-kiota-abstractions and is actively maintained with support for modern Python versions (3.10 through 3.14). It carries no known security vulnerabilities and uses permissive licensing, making it suitable for both commercial and open-source use.

Use it for:

- Handling JSON responses in Kiota-generated Microsoft Graph API clients.
- Serializing request payloads to JSON for OpenAPI-based services consumed via Kiota clients.
- Integrating JSON serialization into custom Kiota-generated SDK projects.
- Converting API response data into Python objects within Kiota client workflows.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Serializes and deserializes JSON payloads for Kiota-generated API client libraries in Python.

Yes, if you are using a Kiota-generated API client library that requires JSON serialization support. Install it as a direct dependency only if you are building custom Kiota clients; otherwise it will be pulled in transitively. The package is stable, actively maintained, and carries no security concerns.

## Install

pip install microsoft-kiota-serialization-json
uv add microsoft-kiota-serialization-json
poetry add microsoft-kiota-serialization-json

## Installing microsoft-kiota-serialization-json

Before you install: Low friction install with a single runtime dependency. Actively maintained as of 2026-08-14 with recent releases and no known security vulnerabilities.

License in practice: Licensed under permissive terms, allowing use in commercial and open-source projects without significant restrictions.

Quickstart:

pip install microsoft-kiota-serialization-json

from microsoft_kiota_serialization_json import JsonSerializationWriterFactory

factory = JsonSerializationWriterFactory()

Requires Python 3.10 or later.

Verify before relying:

- Whether the package is typically used directly or only as a transitive dependency of Kiota-generated clients.
- What specific JSON serialization features or edge cases are handled beyond standard Python JSON support.
