How to use offset on Telegram bot API webHook

Question

Since 2 days I've been exploring the Telegram bot API, which is pretty neat. But there is one thing I can't figure out.

When you don't use the webHook but the /getUpdates call, you can tell the API via the offset parameter which message where processed by the server.

But how do you do this with the webHook in place? I keep getting the same message as an update. Which results in the server spamming the user with the same message.

The solution I came up with is as follows:

1. Receive an update from the webhook
2. Save the update_id
3. Reply to the user /sendMessage
4. disable the webHook /setWebhook?url=
5. Set the offset /getUpdates?offset={update_id+1}
6. Reinstate the webHook /setWebhook?url=https://mywebhook.domain.com

There must be a better way right? Anyone?

Answer 1

Ok, problem solved. It appeared that just a 200 (OK) wasn't enough (the body of my response was null. I've added a body to the response {}, and know it works fine.

Answer 2

You must say to telegram that you get updates successfully with this:

 - 200 response code
 &
 - empty json like this {}
