Kling AI Async Workflows

Overview

Kling AI video generation is inherently async: you submit a task, then poll or receive a callback when done. This skill covers production patterns for integrating this into larger systems using queues, state machines, and event-driven architectures.

Core Pattern: Submit + Callback

import jwt, time, os, requests

BASE = "https://api.klingai.com/v1"

def get_headers():
    ak, sk = os.environ["KLING_ACCESS_KEY"], os.environ["KLING_SECRET_KEY"]
    token = jwt.encode(
        {"iss": ak, "exp": int(time.time()) + 1800, "nbf": int(time.time()) - 5},
        sk, algorithm="HS256", headers={"alg": "HS256", "typ": "JWT"}
    )
    return {"Authorization": f"Bearer {token}", "Content-Type": "application/json"}
