channels.updateUsername can be used to directly assign or change the public username of a supergroup or channel.

channels.joinChannel can be used to join a supergroup or channel using peer information obtained using contacts.resolveUsername.

Private invite links can optionally have an expiration date, a usage limit, and can even be set to only allow users into the channel, supergroup or group upon explicit approval of an admin: see join requests » for more info.
Invite links match the following regex: @(?:t|telegram)\.(?:me|dog)/(joinchat/|\+)?([\w-]+)@i
.
The first matching group can be passed to the hash
parameter of messages.checkChatInvite to get info about the chat, and messages.importChatInvite to join the chat.
messages.checkChatInvite may return chatInvitePeek only for supergroups and channels, in which case the user may directly fetch chat messages using updates, messages.getHistory and channels.getMessages until the time indicated by the expires
unixtime field.
Newly created groups, supergroups and channel already have a default invite link.
To generate a new one, use messages.exportChatInvite.
To get info about existing chat invites, optionally filtering only links created by a given admin, use messages.getExportedChatInvites.
messages.getExportedChatInvite can be used to obtain info about a specific invite link.
messages.editExportedChatInvite is used to edit or revoke existing invite links: revoked links cannot be used by users to join the group, but info about revoked links can still be fetched using messages.getExportedChatInvites with the revoked
flag set.
Use messages.deleteExportedChatInvite to permanently remove an invite link, and messages.deleteRevokedExportedChatInvites to permanently remove a revoked invite link.
messages.getChatInviteImporters can be used to fetch info about users that joined using a specific invite link.
Some basic stats about the number of invite links generated by a given admin can be fetched using messages.getAdminsWithInvites.

Channel administrators can create special invite links that allow joining a channel in exchange for a monthly payment in Telegram Stars.
To create such links, invoke messages.exportChatInvite passing a starsSubscriptionPricing constructor to subscription_pricing
, passing in peer
the private channel we wish to sell access to, and in amount
the amount of Telegram Stars users should pay every period
seconds to gain and maintain access to the channel.
Currently the only allowed subscription period is 30*24*60*60
, i.e. the user will be debited amount
stars every month, and the maximum allowed amount
is specified in the stars_subscription_amount_max
config key ».
Users obtaining info about the invitation link using messages.checkChatInvite will obtain a chatInvite constructor with the subscription_pricing
and subscription_form_id
flags set.
To pay for the subscription, follow the usual payment flow », with the following variation: since subscriptions already have a pre-generated form contained in the subscription_form_id
returned in chatInvite, the first two steps of the payment flow » (those used to generate a payment form) must be skipped, starting directly at the payments.sendStarsForm call in step 3 », passing to invoice
an inputInvoiceChatInviteSubscription with the hash
component of the invite link, and to form_id
the chatInvite.subscription_form_id
.
Once the payment is successfully completed, the user will be automatically added to the channel, without having to invoke messages.importChatInvite to join the private channel.
The end date of the current subscription period will be contained in channel.subscription_until_date
.
If the user decides to leave the channel without cancelling the subscription (or before the end of the current cancelled subscription period), subsequent calls to messages.checkChatInvite will return a chatInvite with the can_refulfill_subscription
flag set, indicating that they may re-join the channel using payments.fulfillStarsSubscription (passing inputPeerSelf to peer
and the starsSubscription.id
to subscription_id
; alternatively, messages.importChatInvite may simply be used) without repeating the payment; the subscription_pricing
will also be returned, but no subscription_form_id
will be returned.
To obtain a list of all active and cancelled subscriptions invoke payments.getStarsSubscriptions, passing inputPeerSelf to peer
: this will return a vector of starsSubscription constructors, containing info about each subscription.
To cancel an active subscription, invoke payments.changeStarsSubscription passing inputPeerSelf to peer
, the starsSubscription.id
to subscription_id
and boolTrue to canceled
; to resubscribe, invoke the same method passing boolFalse to canceled
.
When we get close to the end of the subscription period of one or more active subscriptions, and the current Telegram Star balance is not high enough to autorenew at least one of them, the "STARS_SUBSCRIPTION_LOW_BALANCE" suggestion » will be activated: when the user clicks on the suggestion, the client should fetch and display the list of expiring subscriptions by invoking payments.getStarsSubscriptions, passing inputPeerSelf to peer
and setting the missing_balance
flag: the returned subscriptions may be renewed by filling up the current Telegram Star balance with at least payments.starsStatus.subscriptions_missing_balance
stars.
payments.getStarsTransactions may be used to fetch only and all transactions for a specific subscription by populating the subscription_id
flag.
Admins may also use messages.getChatInviteImporters with the subscription_expired
flag set to fetch only and all users with an expired subscription.
Channel admins can also see the end date of the current subscription period for any user in channelParticipant.subscription_until_date
.

If the request_needed

RPC error, indicating that an join request was successfully sent to the chat admins.
Related supergroup information will also have the channel.join_request
flag set accordingly.
Bot administrators will receive a updateBotChatInviteRequester update for each separate join request.
User administrators will receive an updatePendingJoinRequests, and should invoke messages.getChatInviteImporters with the requested
flag set to obtain a list of users waiting to be admitted into the group.
Administrators can then use messages.hideChatJoinRequest to approve or dismiss a join request, and messages.hideAllChatJoinRequests to approve or dismiss in bulk multiple join requests.
Administrators can also choose to send a message to the user before admitting them into the group: in this case, graphical clients on the user side should display a message on the dialog bar of the chat with the admin, indicating that the chat was initiated by the admin of a chat/channel they have recently requested to join, see the action bar documentation » for more info.

Users may also be directly invited to groups and channels during their creation (basic groups via messages.createChat) or afterwards (basic groups via messages.addChatUser, supergroups and channels via channels.inviteToChannel).
The methods will return a messages.invitedUsers constructor, containing a list of updates about successfully invited users (and eventually info about the created group), and a list of missingInvitee, with a list of users that could not be invited for some reason.
Specifically:
premium_would_allow_invite
flag is set, we could not add the user only because the current account needs to purchase a Telegram Premium subscription to complete the operation. premium_required_for_pm
flag is set, we could not add the user because of their privacy settings, and additionally, the current account needs to purchase a Telegram Premium subscription to directly share an invite link with the user via a private message.
