In this section, you’ll be shown the alternative way of communicating with Telegram using Pyrogram: the main “raw” Telegram API with its functions and types.
Telegram Raw API¶
As already hinted, raw functions and types can be really confusing, mainly because people don’t realize soon enough they accept only the right types and that all required parameters must be filled in. This section will therefore explain some pitfalls to take into consideration when working with the raw API.
Every available high-level methods in Pyrogram is built on top of these raw functions.
Nothing stops you from using the raw functions only, but they are rather complex and plenty of them are already re-implemented by providing a much simpler and cleaner interface which is very similar to the Bot API (yet much more powerful).
If you think a raw function should be wrapped and added as a high-level method, feel free to ask in our Community!
Unlike the methods found in Pyrogram’s API, which can be called in the usual simple way, functions to be invoked from the raw Telegram API have a different way of usage and are more complex.
First of all, both raw functions and raw types
live in their respective packages (and sub-packages):
pyrogram.raw.types. They all exist
as Python classes, meaning you need to create an instance of each every time you need them and fill them in with the
correct values using named arguments.
Next, to actually invoke the raw function you have to use the
send() method provided by the
Client class and pass the function object you created.
Here’s some examples:
Update first name, last name and bio:
from pyrogram import Client from pyrogram.raw import functions with Client("my_account") as app: app.send( functions.account.UpdateProfile( first_name="Dan", last_name="Tès", about="Bio written from Pyrogram" ) )
Disable links to your account when someone forwards your messages:
from pyrogram import Client from pyrogram.raw import functions, types with Client("my_account") as app: app.send( functions.account.SetPrivacy( key=types.PrivacyKeyForwards(), rules=[types.InputPrivacyValueDisallowAll()] ) )
Invite users to your channel/supergroup:
from pyrogram import Client from pyrogram.raw import functions, types with Client("my_account") as app: app.send( functions.channels.InviteToChannel( channel=app.resolve_peer(123456789), # ID or Username users=[ # The users you want to invite app.resolve_peer(23456789), # By ID app.resolve_peer("username"), # By username app.resolve_peer("+393281234567"), # By phone number ] ) )
The way Telegram works makes it impossible to directly send a message to a user or a chat by using their IDs only.
Instead, a pair of
access_hash wrapped in a so called
InputPeer is always needed. Pyrogram allows
sending messages with IDs only thanks to cached access hashes.
There are three different InputPeer types, one for each kind of Telegram entity. Whenever an InputPeer is needed you must pass one of these:
But you don’t necessarily have to manually instantiate each object because, luckily for you, Pyrogram already provides
resolve_peer() as a convenience utility method that returns the correct InputPeer
by accepting a peer ID only.
Another thing to take into consideration about chat IDs is the way they are represented: they are all integers and all positive within their respective raw types.
Things are different when working with Pyrogram’s API because having them in the same space can theoretically lead to collisions, and that’s why Pyrogram (as well as the official Bot API) uses a slightly different representation for each kind of ID.
For example, given the ID 123456789, here’s how Pyrogram can tell entities apart:
-100IDChannel or Supergroup: -100123456789
So, every time you take a raw ID, make sure to translate it into the correct ID when you want to use it with an high-level method.
