fastapi-security-typeform

Security plugin for FastAPI which allows you check Typeform signature in your webhook endpoint.

How to setup signing flow for your typeform webhook

Current flow is here https://developer.typeform.com/webhooks/secure-your-webhooks/ (it's little bit a lie about working only via API)

tl;dr:

• create a webhook via UI or API
• generate random string (secret)
• update a webhook via UI or API with your secret

How to use

Use pip or another package management util:

pip install fastapi-security-typeform

or

poetry add fastapi-security-typeform

or

pipenv install fastapi-security-typeform

Then initialize it with your webhook secret and pass it to endpoint as dependency.

It will raise 403 error if signature isn't valid.

from fastapi import Depends, FastAPI

from fastapi_security_typeform import SignatureHeader

app = FastAPI()
signature_header_security = SignatureHeader(secret=b'{your_secret}')

@app.post("/typeform_webhook")
def typeform_webhook(signature = Depends(signature_header_security)):
    ...
    return {"success": True}
