Telegram official api

I need someone to host telegram official api for me so I should be able to do api actions from my server/postman on it. For this if any hosting service / digital ocean is required will provide.

Through official api I aim to achieve this (already available in api) :
- Create new group/channel
- Query members in a group / channel created by me
- Add / remove members
- Send message on a group / channel created by me
