Custom API in Business Central

Today, I will demonstrate how to work with custom API in Business Central. Custom API is very useful when we are working with integration apps. So, lets start exploring custom API in business central.

We will take one table called student and will create one API page in order to access this table as API. Moreover, we can check this API in Postman as well. Here, we will mainly perform three operations GET, Post, and Delete.

First of all, we will create student Table with four fields ID, First Name, Last Name and Email. For the primary key we will take ID.


Once table is added, we will create one list page to view our data. So, we can easily check our custom API is working properly or not.


Now, we will add another page which is used as API. This is a new page type introduced in business central. You can check how to create API page in business central.(Click Here)


Now, we can interact with student  data with the help of this API page in the business central. We will write a logic in codeunit for calling this API.





Now, we will create three actions on the list page. First one is for getting data from the table. Second one is used to insert data. For the second action we will use report to enter data. For the third one we will use to delete our data from the table.




This is the report that I have created for importing a data.





Now, we will check how custom API will work in the Business Central.

I am using docker sandbox environment for this. May be API URL can be changed as per your environment and company that you are using.

  1. Warning AL0604: Use of implicit 'with' will be removed in the future. Qualify with 'Rec.'. This warning will become an error in a future release.

    You should start using
    field(Id; Rec.ID) instead of field(Id; Rec.ID)
