API stands for application programming interface, which allows servers to communicate with Each Other. API does interpolation between servers. Many old companies have rebuilt CRM or purchased it from a third party. 

Many big tech Companies, such as Google, Facebook, and Spotify, have APIs that provide them with different kinds of features. 

Display data not hosted on your server or domain from one page to the second page. 

So, should your CRM have an API or not? 

If you are wondering whether you should be an HRM developer, remember that API development is beneficial. However, it can also threaten your system if you cannot manage the API, which is ultimately connected to the database. This can cause many problems. 

Let's understand how APIs work and how you can use them. APIs play a massive role in your CRM or different management systems. APIs are created on top of routes, which are the places where different pages of your CRM are connected. 

These pages are also authorized and unauthorized, that is, those pages where login is required and those where login is not required. For example, you have shared a block post through your CRM or your CMS, and you want that block post to be visible on my other server, which you do not have. If it is on another server, you can request the developer to create an API for a CRM. 

The API scheme will have a client-side and a server side. Both will play different roles in their respective places, and whether they are authorized will be determined. This means that everyone can see it, or only a few people will be able to see it. 

Many companies in the market only provide some of their APIs. The main reasons for this are the risks of hacking and having a large number of data bridges. This risk is very high when data from different companies is in the same database, or when a larger team is needed to manage all these things.
