"""
This code adapts the following code for Linear.app. It is not official code.
https://github.com/huggingface/huggingface_hub/blob/main/src/huggingface_hub/_webhooks_server.py
https://github.com/huggingface/huggingface_hub/blob/main/src/huggingface_hub/_webhooks_payload.py

Currently, it only supports a small subset of the Issue Object.
https://studio.apollographql.com/public/Linear-API/variant/current/schema/reference/objects/Issue

You need to set `api_key = linear-api-key` and `webhook_secret = linear-webhook-secret` in your `.env` file.

Since the local URL changes with each startup, the URL is updated in the Linear API at startup.
At startup, it overwrites the webhook with the label specified by `target_webhook_label` (default value: Gradio).

You need to pre-install gradio, fastapi, and pydantic.
You need to describe your Linear API key and Linear webhook secret in the `.env` file.
Also, since this example is only for Update, please create a Webhook with the label Gradio beforehand.
