Webhook setup via URL returns blank

[azickri]

Bug Report

I have read:

• Usage information
• Help information

I am using the latest version of the library.

Expected Behavior

I want to setup Webhook URLs directly using the API

Actual Behavior

I have tried to set Webhook via Telegram API directly with API as follows

https://api.telegram.org/{token}/setWebhook?url={webhookURL}

When I retrieve information about the Webhook with the API as follows

https://api.telegram.org/{token}/getWebhookInfo

The first time you retrieve information quickly after setting it up it matches the webhookURL you set, after a few seconds it returns to blank.

{
   "ok": true,
   "result": {
     "url": "",
     "has_custom_certificate": false,
     "pending_update_count": 0
   }
}

Steps to reproduce the Behavior

1. Create a BOT Token
2. Integrate BOT with this Package
3. Set Webhook URL using API https://api.telegram.org/{token}/setWebhook?url={webhookURL}
4. Retrieve Webhook related Information using API https://api.telegram.org/{token}/getWebhookInfo
