How To Use an API with Spring RestTemplate

This is a summary of the text in one paragraph: In this tutorial, we connect to three different RapidAPI application programming interfaces (APIs) using Spring Boot. First, we explore using HTTP GET to obtain COVID-19 totals from the COVID-19 data API on RapidAPI. Second, we explore using HTTP POST to upload an image and generate a meme using the Meme Generator API on RapidAPI. And Third, we use HTTP POST to send a JSON request to the Microsoft Computer Vision API to generate a thumbnail from an image provided using a URL. We use Spring Initializr to generate a Spring Boot Rest application, create a Spring RESTful client that uses Spring's RestTemplate to call a REST endpoint using a GET request, and add a method to our Spring Boot Rest client that passes a query parameter to a GET REST endpoint. We also create a Spring Boot RestTemplate client that sends binary data to a REST endpoint using a POST request.
