Update Code from Git/Bitbucket to live server - version-control

How can i update my live server with the changes i made through Git/Bitbucket?
Is there any free service ?
Is it possible to do it with some kind of API which can be integrated with cronjob?

You could use the BitBucket service hooks.
They are illustrated in "Using Bitbucket for Automated Deployments", and that article uses the POST service.
Bitbucket POSTs to the service URL you specify.
The service receives an POST whenever user pushes to the repository.
The content header of the POST has an application/x-www-form-urlencoded type.
This services behaves similarly to an HTTP publish/subscribe service.
The payload has payload= prepended to the actual payload. The payload is url encode content.
The body of POST request contains information about the repository where the change originated, a list of recent commits, and the user that made the push.
Regarding GitHub, see this process which describes how to use the Post-receive hook

How to format Status Check Responses in Azure Devops Pull Requests

I have a branch policy that enforces the use of pull requests into a specific branch.
The policy also requires that an external status check is passed, in this case a web hook is triggered by the creation or update of the pull request. The web hook calls a web api which updates the status of the pull request via the devops REST API to set the required state check to succeeded or failed and include a description.
The description posted to the devops REST API is then displayed in the pull request in the event of a filed status check. For example:
I have control of the content of the returned description from the web api endpoint, and I am looking for a way to control the formatting of the displayed message in the pull request. Specifically a way to break the text over multiple lines.
I have tried adding a <br/> (shown above) or \n or \r or even \r\n to the text, all with no success.
Is it possible to do this? is there any parsing of the returned text, maybe to allow the use of something like markdown?

Webhook and API (Defination & Diffrences)

I want to know about webhook (what is webhook). What is the application of webhook (a real world scenario). Besides, what are the differences between webhook & API?
An API is a standardised way of communicating with a service. You've tagged REST in your question so I'll focus on RESTful APIs using HTTP but it is important to know that API is a very generic term.
In the REST world everything is a resource and you use the HTTP methods to define what action you want to take on or apply to that resource. For example, to list all the users on GitHub you would send a GET request to https://api.github.com/users. The URL (specifically the /users part) defines what resource you are interested in. Here the resource is a collection of all the users. There's other methods you can use; such as PUT to create or update a resource. To learn more about the different methods you can read the HTTP specification.
Webhooks are often used in conjunction with APIs but they are focused on events. They allow a service to send out 'notifications' when an event happens or some condition is met.
GitHub is again a good example of what webhooks are used for. Say I'm building a service which sends out an email every time someone leaves a comment on an issue in GitHub. I could use the GitHub API (like above) to list all of the comments on an issue and then check if there have been any new comments since the last time I checked. I can then just repeat this request every few seconds. This is known as polling. The issue here is that most of the time I'm checking the result is not going to change. This is going to be a waste of resources.
Webooks allow for Event-Driven Programming. Instead of randomly checking I can instruct GitHub to send my service a HTTP request every time a comment is added: aka a webhook. In this architecture I only have to send a request to GitHub's API when I know for sure that a new comment has been left.
Overall, you cannot really compare APIs and webhooks. The link between them is simply that webhooks send requests to APIs.

How do I check if an issue is a pull request?

I'm building a Github App. I receive an issue_comment webhook. Is there any quick way for me to know whether the comment was made in a pull request of not?
From the Issues API docs...
Note: GitHub's REST API v3 considers every pull request an issue, but not every issue is a pull request. For this reason, "Issues" endpoints may return both issues and pull requests in the response. You can identify pull requests by the pull_request key.
You should be able to look at comment["issue"]["pull_request"].

Github Pull Request Checks

Is it possible to create a Github Check for pull requests? I know there are WebHooks, but is there a way to also hook into the UI?
Aim:
Pull Request made. Perform validation and update pull request if valid.
Pull Request merged. Create web call to URL. Update Github issue with confirmation.
What's the best way to do this? Is it only via Web Hooks, API calls and getting write oAuth credentials?
Note: you now (August 2018) officially have the notion of Checks
When checks are set up in a repository, pull requests have a Checks tab where you can view detailed build output from status checks and rerun failed checks.
I know there are WebHooks, but is there a way to also hook into the UI?
The recommended way of doing this is to use required status checks and the Status API, in combination with webhooks:
https://help.github.com/articles/about-required-status-checks/
https://developer.github.com/v3/repos/statuses/
Users set up required status checks on the repository so that merging a pull request is blocked if a specific status isn't success.
At the same time, webhooks trigger an external process when a pull request is updated, and that process creates statuses based on the output of that process. If the process completes successfully, then the process should create a success status which will be shown in the UI and unblock the merging of the pull request.
Is it only via Web Hooks, API calls and getting write oAuth credentials?
In order to create statuses, you will indeed need to authenticate with the credentials of a user that has push access to the repository (e.g. via a token from that user with the right scopes).

How to get pull requests references for an issue

Given a GitHub issue, is there any way to get the pull requests that reference to that issue via API?
That info is showed in the GitHub html page but I can't see nothing in the API documentation.
Is it really possible?
is there any way to get the pull requests that reference to that issue via API
Not directly.
Even the reverse is not possible, as a pull request has a link 'issue' pointing to... itself.
But as mentioned in the issue API:
In the past, pull requests and issues were more closely aligned than they are now.
As far as the API is concerned, every pull request is an issue, but not every issue is a pull request.
This endpoint may also return pull requests in the response. If an issue is a pull request, the object will include a pull_request key.
So you would need to list the comments of a pull request (using the Issue Comments API since comments on PR are done with it), and parse said comment to find a reference to an issue.
