# mypy-boto3-appflow — Type annotations for boto3 Appflow 1.43.23 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 5.4M/mo

## What it is and what it does

This package is a type stub library that adds static type information for boto3's Appflow service. It is generated from boto3 1.43.23 using mypy-boto3-builder 8.12.0 and works with VSCode, PyCharm, Emacs, Sublime Text, mypy, pyright, and other type-aware tools. When installed, it enables IDE code completion and catches type errors at development time without requiring explicit type annotations in your code.

The package contains type definitions for Appflow client operations, literals for valid parameter values, and type definitions for request and response structures. It is designed as a development-time dependency and can be used conditionally with TYPE_CHECKING to avoid runtime overhead in production code. The library supports Python 3.9 through 3.14 and has no external dependencies beyond typing-extensions.

Use it for:

- Enable IDE autocomplete and type hints when writing boto3 Appflow client code in VSCode or PyCharm.
- Run mypy or pyright type checking on boto3 Appflow code to catch type errors before runtime.
- Provide explicit type annotations for Appflow client, request/response structures, and valid literal values.
- Use in a TYPE_CHECKING block to add type safety during development without adding a production dependency.

## Worth the install?

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

Provides type annotations and IDE autocomplete support for boto3's Appflow service, enabling static type checking with mypy, pyright, and other tools.

Yes, if you use boto3 Appflow and want IDE autocomplete or static type checking. Install friction is minimal, maintenance is active, and the MIT license has no restrictions. The only caveat is PyCharm may experience performance issues with full type stubs; in that case, use boto3-stubs-lite instead. For mypy, pyright, VSCode, or other type checkers, this is a straightforward win.

## Install

pip install mypy-boto3-appflow
uv add mypy-boto3-appflow
poetry add mypy-boto3-appflow

## Installing mypy-boto3-appflow

Before you install: Low friction install with a single runtime dependency (typing-extensions). Actively maintained with recent releases; repo shows 670 stars and last commit on 2026-06-22.

License in practice: MIT license permits unrestricted use, modification, and distribution in both open-source and proprietary projects.

Quickstart:

pip install mypy-boto3-appflow

from boto3.session import Session
from mypy_boto3_appflow import AppflowClient

client: AppflowClient = Session().client("appflow")

Requires Python 3.9 or later; boto3 must be installed separately in your environment.

Verify before relying:

- Whether PyCharm performance issues mentioned in the docs (issue PY-40997) remain unresolved or have been addressed.
- Whether the lite variant (boto3-stubs-lite) is recommended as a default for PyCharm users or only when performance degrades.
