API Documentation​

Security​

The API employs several security measures to ensure the integrity and confidentiality of your data:

  • Authentication: All API requests require an API key to be included as a query parameter. This key uniquely identifies the client making the request and provides access control to the API endpoints.
  • HTTPS: Communication with the API is always encrypted over HTTPS, ensuring that data transmitted between the client and the server remains confidential.
  • Input validation: The API performs input validation and sanitization to prevent common security vulnerabilities such as SQL injection or cross-site scripting (XSS) attacks.

Base URL​

Authentication​

The API uses an API key for authentication. The API key must be included as a parameter in all requests.

Authentication Parameters​

  • api_key (required): The API key to authenticate the request.

Available Resources​

MagicApi library
# B4X Library Documentation

## Description
This library provides methods for performing CRUD (Create, Read, Update, Delete) operations on an API. It is designed to interact with an API that uses JSON as the data exchange format.

## Installation
1. Download the MagicApi.b4xlib library file.
2. Copy the MagicApi.b4xlib file to the additional libraries folder in your B4X development environment.

## Initialization
Before using the library methods, you need to initialize it by calling the `Initialize` method and providing the following parameters:
- `CallbackModule` (Object): the name of the callback module where the events handling API responses are located.
- `cEventname` (String): the base name for the response events.
- `urlbase` (String): the base URL of the API.
- `api_key` (String): The api key defined in the php file.

## Events
The library generates response events for each CRUD operation. These events should be implemented in the specified callback module during initialization.

### Generated Events
- `EventName_Insertmaps(m As Map, success As Boolean)`
- `EventName_Delete(tablename As String, success As Boolean)`
- `EventName_DeleteByColumn(tablename As String, success As Boolean)`

**Security**

The API prioritizes security and implements various measures to safeguard the integrity and confidentiality of your data:

1. **Authentication**: To access the API, every request must include an API key as a query parameter. This key serves as a unique identifier for the client making the request and grants access control to the API endpoints.

2. **HTTPS**: All communication with the API is encrypted using HTTPS. This ensures that data transmitted between the client and the server remains confidential and protected from unauthorized access.

3. **Input Validation**: The API incorporates robust input validation and sanitization techniques. By doing so, it guards against common security vulnerabilities like SQL injection and cross-site scripting (XSS) attacks. This helps maintain the integrity of the data and protects against malicious input.

For users who have previously obtained an earlier version, they can access the store and log in to their user panel. In the "Recent Orders" section, they will find the option to view their order and download the updated Version 2.0 of the API.

Think about magic for
1) searching records by a part of field's value, ">", "<", ">=", "<="...
2) pagination of the output

Yes, this API fulfills the following requirements:

1) **Searching records by a part of field's value, ">", "<", ">=", "<="...**: The API has the ability to search for records using comparison operators such as ">", "<", ">=", "<=", and more. This allows you to perform more specific queries and obtain results based on custom conditions.

2) **Pagination of the output**: The API supports pagination of the results, allowing you to retrieve smaller data sets and control the number of records returned in each response. This is useful when dealing with a large number of records and you want to divide them into pages for better navigation and performance.

In summary, this API provides functionalities for searching records by a part of a field's value and for paginating the results, thus meeting the mentioned requirements.

Hi buddy @fernando1987 ,
Have you thought about adding the ability to send and receive a bmp/jpg/png in your magicApi?
in the case, for example, of a user table, where it is entered, Name, Surname, Photo, etc.
