[Deen12520]

Hello.
I use the line-bot-sdk-python to generate a Webhook, but I don't success.
I have watch your tutorial videos,but you skip this part. And I know how to deploy my project on Heroku.

Can you share your files which use to generate Webhook?

I need your help. Thanks a lot.

First make sure the request has been sent to your server

try response 'OK'

Hi @twtrubiks

I have tried with response OK too but the validation is failing. However, the response from LINE Api is successfully sent.

I am getting proper dummy response from webhook in LINE API as below:
{"destination":"U70371917134f788a6b8fd7620b139b4c","events":[]}

Do we not get success while verifying the webhook in LINE account?

Thanks

Do we not get success while verifying the webhook in LINE account?

Because the programming language you use is different from mine. I use Python Flask and the Python line bot SDK.

Which VPS is yours? I use Linode

Hi @twtrubiks

I am using Liquid Web. Are you getting success response when verifying URL in webhook in LINE messaging API?

yes. i use

@app.route("/callback", methods=['POST'])
def callback():
    # get X-Line-Signature header value
    signature = request.headers['X-Line-Signature']

    # get request body as text
    body = request.get_data(as_text=True)

    # handle webhook body
    try:
