Get the userid in telegram - telegram

I'm using #username_to_id_bot to retrieve the user_id.
Sometimes the user doesn't have a username.
How can I retrive in this case?

For each user response the Telegram payload includes information like user_id and chat_id.
You can always access these navigating the JSON.
When processing a simple text response
update.message.from_user.id
When processing a Callback Query
update.callback_query.from_user.id

If you are using web application, in address bar you can see URL like following:
https://web.telegram.org/#/im?p=u1111111111_2222222222222222222
In this case 1111111111 is the user_id which you are looking for.

How to forward (filter) Telegram messages from a private group to myself based on sender?

I'm in a private Telegram group that has a continual stream of many messages from a large number of people. I need to somehow pull out just those from a handful of specific people, and forward them to myself somehow - e.g. a new group I'm the only member of, or private chat, or some other way (email?). I just need to read them, not reply.
I'm a full stack developer (PHP back end but willing to consider others if works better) and know how to interface with APIs etc so can write some code to do this.
Can anyone advise on what API functions I'd use, or other approach here - and is it the Telegram or Bots API? Or is there a pre-existing solution out there?
Asking here as I've done my own research and not finding any solutions!
You can create a bot and put it in the private group. Set the bot as administrator so it can read all messages from all users. For each message the users send in the group, the bot will recive an update containing a message object. The message object contains all the information about the message just sent in the group, including the user's data. To filter a message from a specific user you can compare the user_id in $update['message']['from']['id'] with an array containing all the user_ids of the users you want to forward their messages to you, with the in_array php function passing the user_id and the array. Then, if it match, use the forwardMessage method with these parameters:
{
"chat_id": "YOUR_USER_ID",
"from_chat_id": "PRIVATE_GROUP_CHAT_ID",
"message_id": "THE_FILTERED_MESSAGE_ID"
}
If you use your user_id in the chat_id field, the bot will forward the message from the private group to your chat with it. The from_chat_id field is the chat_id of the private group (you can get it from $update['message']['chat']['id']). The message_id is the unique identifier for a message in that private group. It's contained in $update['message']['message_id'].
Instead of comparing the user_id to filter users, you can compare the first_name, last_name or username of the users but only the user_id is unique for each user and can not be changed.
You are using the Bot API.

Firebase Cloud Firestore request

I have a MESSAGERECAP collection which includes a unique id for each message, the id of the receiver of the message, the id of the sender and the message itself. In my application, when the user clicks on a friend to chat with him, I want the chat activity to start with the list of messages they have both sent.
I did this but obviously it does not give the desired result :
Query query = messageRef.orderBy("mssgId",Query.Direction.DESCENDING);
// with messageRef a reference to the MESSAGERECAP collection
Here is an overview of my database
You are getting the whole list because you are not filtering the data, just ordering it. If you check the Querying documentation for Firestore, also provided by #FrankVanPuffelen on the comments of your question, you can see that you have to use .where() to filter the data that you want to retrieve.
Also, as pointed out by #Jay in the comments, you can use Compound Queries to create a logical AND on your query to retrieve the data you want.
So if you do something like:
messageRef.where("senderId", "==", [currentUserId])
.where("receiver_id", "==", [receiverUserId])
.orderBy("mssgId",Query.Direction.DESCENDING)
When you execute this query you will get all the messages sent by the current user to the receiving user of the correponding id.

How to fetch email marketing insights data from Marketo using API?

I am trying to fetch "Email Performance Report" from the platform
using API to analyze the KPI's like CTR etc by type of the email
(newsletter,email marketing etc).
I went through the documentation, however I didn't find endpoint from
which I can fetch the same.
Does anyone know if there is a way to get this information?
There is no endpoint to query reports directly. However, the good news is, that the “things” that make up an “Email Performance Report”, namely: email delivery, bounce, open and click are available to query via the API.
This means that you have to build the report yourself, but you can fetch the dataset to work on.
These “things” are called activity types (activity measured on a Lead) and can be fetched by querying against the Get Lead Activities endpoint, which is also mentioned as the Query in the API docs.
It sits at the GET /rest/v1/activities.json url and you have to pass a nextPageToken and the activityTypeIds as query parameters.
The nextPageToken indicates a datetime. Activities after that date will be returned by the call. To obtain one, you have to make a call to GET /rest/v1/activities/pagingtoken.json, where you have to specify the earliest datetime to retrieve activities from. See more about Paging Tokens.
To figure out the value of activityTypeIds, you first need to get the internal Ids of the activity types you are interested in. In order to do so, you have to query the GET /rest/v1/activities/types.json endpoint and look for the activity types with names like Send Email, Email Delivered, Email Bounced, Unsubscribe Email, Open Email and Click Email. (I don't know if these Ids are changing from instance to instance, but in ours these are from #6 to #11).
Once you have all of these bits at hand, you can make your request like that:
GET https://<INSTANCE_ID>.mktorest.com/rest/v1/activities.json?activityTypeIds=<TYPE_ID>&nextPageToken=<NEXTPAGE_TOKEN>&access_token=<ACCESS_TOKEN>
The result it gives is an array with items like below. Items can be filtered to specific email based on the primaryAttributeValue property and processed further accordingly.
{
"id":7370416,
"marketoGUID":"7170506",
"leadId":291305,
"activityDate":"2017-12-17T00:00:00Z",
"activityTypeId":11,// #11 = `Click Email`
"campaignId":1790,
"primaryAttributeValueId":1638,
"primaryAttributeValue":"EMAIL_NAME",// Name of the Email as seen in Marketo
"attributes":[
// …
]
}

Custom metric to track email opens

I am trying to track the number of email opens of a mailing.
This mailing is not personalised, so each receiver will get exactly the same email contents.
So far I have found out that I can add a tracking pixel in the mailing, which will send data to GA that a user opened the mail (images were loaded).
Example code:
<img src=”http://www.google-analytics.com/collect?v=1&tid=UA-XXXXXX-X
&cid=EmailOpenTest&t=event&ec=email&ea=open&el=EmailOpenTest
&cs=newsletter&cm=email&cn=Email&cm1=1″ />
'tid' will be our custom tracking ID.
This all works, as when this link is opened the total number of hits increases.
But my question relates to parameter 'cid'. For testing purposes, I have set this here to "EmailOpenTest". But this should be a random/unique ID per user actually. But as the mailing is not personalised, I wonder if it would be possible to track individual users?
Does this mean I have to include javascript in the mail? Would that even work in all email clients? Or are there other options?
All suggestions are welcome.
Assumption: you are using a mail client like Mail Chimp
Assign a unique id to every email on the email list. lets say this unique id is uid
Create a custom dimension in GA, lets name it as Client Mail Id with index say 1
Create the same pixel just like you have created above in the OP.
Add a custom Dimension in the hit as
http://www.google-analytics.com/collect?v=1&tid=UA-XXXXXX-X
&cid=EmailOpenTest&t=event&ec=email&ea=open&el=EmailOpenTest
&cs=newsletter&cm=email&cn=Email&cm1=1&cd1=uid
In place of uid, you actually need to pass the mail list unique id for that email
How it will work
Once the user sends this hit, your unique id will be recorded in custom dimension 1.
Generate a custom report in GA with event category=email & event action=open and add a dimension custom dimension 1.
All the id's displayed there have actually opened the email ;)
PS: It's tried and tested, so won't cause any issue. Also if you don't want to use custom dimensions, you can also send this id in event label or event value
PPS: In any mail client, getting unique value for that email is pretty easy. You can actiually use its position number or add another column for the unique id, then grab that id win the template
The cid is the clientId, an identifier that is used to aggregate pageviews into sessions, and sessions into unique users.
The way to use that in email-tracking would be to capture the client id when a user subscribes to your newsletter and then insert it into the email links. Since your mails are not personalized this will not work.
If you use a random ID you will not be able to link the request from the mail to an existing user. So one way to deal with the problem would be to ignore it - using a constant userId would still give you an event count (the unique events metric might be a little of if users click the link multiple times within a session lifetime).
If for some reason you absolutely need to track these as different users you can set up a redirect - do not send data to ga directly from your mail, instead call a script on your server that inserts a random clientId and then sends the data to Google.

Ensuring user is updating its own record

I'm building a simple web form which allows user to edit there data like email, emergency contact etc.
The edit form is rendered using Asp.NET MVC 5. Proper html fields are rendered for Id, email, emergency contact etc.
Lets say the request to save the data is received by the following controller method.
SaveData(recordId, email, emergencyContact)
{
;
}
Question: How do I make sure that recordId was indeed the id that was rendered as part of the edit form? We don't want this user to update another user's record.
I have the following options in mind
1. Create a hash of the record id and send the hash as well.
2. Ensure user is authorized to modify the record indicated in given record id.
Is there any other way? Does MVC 5 provide any features so that I don't have to put this sort of logic in my application logic?
Typical approaches are:
Store the ID of the record as a hidden field. If you are concerned with hijacking, encrypt the value and decrypt on the server.
Store the ID of the record in session; this way, you always pull back the record and keep the value on the server. But when session dies, so does the link to the record.
Yes I'd highly recommend check permissions to the record if you store the ID in the URL.
