I've used SOAP protocol in the telecommunication industry for a project involving the migration of customer SIM cards between two companies. When we started to work with SOAP, the SoapUI (a windows software) became a must, but it cannot be incorporated to the ETL we were building on a Linux server, so we ended up recreating their request to Postman, then exporting the command, and finally creating the bash request we all know about.

One of the reasons to use an API is for Data Extraction. There are multiple APIs which are popular for Data Extraction. They are as follows 1. Database APIs 2. RESTful APIs 3. SOAP APIs 4.GraphQL APIs When it comes to data extraction, we should also consider a technique called "web scraping". It involves extracting data directly from web pages. For example, in python, we can make use of libraries like 'requests', 'grequests' to extract the html file and we can use 'BeautifulSoup' to parse and find the data that we are looking for.

The most common types of APIs used for data extraction include: Web Scraping APIs: Tools like BeautifulSoup (Python), Puppeteer (JavaScript), Scrapy (Python), or requests-html (Python) facilitate web scraping by parsing HTML and extracting data from websites. Database APIs: Libraries such as JDBC (Java Database Connectivity), SQLAlchemy (Python), or Sequelize (Node.js) enable interaction with databases like MySQL, PostgreSQL, SQLite, and others, allowing the extraction of structured data. Cloud Service APIs: APIs provided by cloud platforms like AWS SDK, Google Cloud Client Libraries, or Azure SDK offer access to various cloud services for data extraction from storage, databases, or other services hosted in the cloud.

To extract data using APIs, first, obtain API access, then authenticate (API key, OAuth). Understand endpoints and parameters for desired data. Make HTTP requests (GET, POST) to relevant endpoints, handle pagination for large datasets, and parse responses (JSON, XML). Implement error handling, retries, and data processing. Finally, ensure compliance with rate limits, security, and API terms.

Steps to use APIs for data extraction: ??Understand the API Documentation: This is the first step, one must understand the documentation detailing API endpoints, parameters, and authentication. ??Authentication: To connect to the API, first you need to obtain the API credentials (API key, OAuth tokens) as per documentation. ??Choose the right Endpoint: Identify the specific API endpoint for desired data extraction. ??Construct Requests: Build HTTP requests (GET to extract data) with necessary parameters and headers. ??Make Requests: Use tools or programming languages to send requests and retrieve data. ??Handle Pagination: Manage pagination if the API paginates results. ??Parse Data: Parse API responses and extract relevant data.

The most common data extraction APIs typically involve web-based services, offering different protocols like REST, SOAP, or GraphQL. These APIs are used to access and retrieve data from various sources. The process involves crafting a request, which includes selecting the appropriate method, parameters, and any necessary headers or body content. After sending the request, the received response is parsed, taking into account its format and any potential errors. The final step is the transformation and storage of the data, which can be done using various data management systems like data warehouses or lakes. This approach allows for the effective organization and analysis of the extracted information.
