**How to set this up:**

- **On Space B:** You need to build your Space so that it exposes a web endpoint. A common way to do this is using a **Docker Space** running a lightweight `FastAPI` server, or using the `@webhook_endpoint` decorator provided by the `huggingface_hub` Python library in a Gradio Space.

- **In your HF Settings:** You go to your user/organization Webhooks settings, select Space A as the “Target Repository,” and paste the Direct URL of Space B as the destination.

- **Security:** You configure a Webhook Secret in your settings and set that same secret as an Environment Variable in Space B. Space B’s code should verify the `X-Webhook-Secret` header so it only accepts requests from Hugging Face.
