FAQs
How to send messages to multiple groups
You just have to send multiple API requests, one per target group.
For instance, if you want to send a message to 10 groups, you should send 10 independent HTTPS requests to the API.
There is no option to send multiple messages in a single API request.
What type of messages can be sent?
You can send different types of messages, including text, images, videos, emojis, audio, gifs, geographic locations and file documents via API.
Check out other tutorials for more information.
