Sending photo with Telegram-messenger using http-request node

[Egg Nine]

Hi,

I am trying to send a photo with Telegram messenger using an URL request with a http-request node. For some reason my photo is not being sent.
It seems I have problems indluding the photo (/tmp/img.jpg) itself.

This is what I put in the http-request node fields:

msg.url="https://api.telegram.org/bot12345678/sendPhoto?chat_id=-1234567890&photo=/tmp/img.jpg";
msg.headers = {"Content-type" : "multipart/form-data"};
msg.method="POST"

When I run a curl command from the cli it works:
curl -F photo=@/tmp/img.jpg -H "Content-Type:multipart/form-data" "https://api.telegram.org/bot123456789/sendPhoto?chat_id=-123456789"

Can someone advice how I can translate the curl command into a http-request node?

Thanks,
Rene

Can;t help with that but have you tried the 2 different nodes that talk to Telegram?

I don't use telegram API url directly, but as Julian wrote you can use chatbot nodes for that.

Here an example using chatbot

This sends an image picked from the web, but you can use file image too
