Check the verification code

To verify the code submitted by the user you make a call to the Verify check endpoint. You pass in the request_id (which was returned by the call to the Verify request endpoint in the previous step).

The response tells you if the user entered the correct code. If the status is zero then the code they entered is the same one that they were sent. In that case, create a user session object.

After checking the code, return your user to the home page.

Enter the following code in the /check-code route handler to achieve this:

@app.route("/check-code", methods=["POST"])
def check_code():
    response = verify.check(session["request_id"],
                            code=request.form.get("code"))

    if response["status"] == "0":
        session["verified_number"] = session["unverified_number"]
        return render_template("index.html",
                               number=session["verified_number"],
                               brand=VONAGE_BRAND_NAME)
    else:
        return render_template("index.html", error=response["error_text"])
