For example, if they’ve downloaded our tool but haven’t used it yet, we can send them a personalized message on LinkedIn saying: □ At Waalaxy, our strength has been to automatically retrieve the LinkedIn URLs of people who signed up with us, and thus be able to retarget them in campaigns, to keep the link throughout the conversion tunnel. □ Digital prospecting, it may seem complex, especially with APIs, but promise the tuto is ultra-easy to reproduce, just copy and paste. You can use this online Python client to run the code.In this Live + Tutorial summary, we’re going to explain how to take your marketing strategy to the next level to prospect for new customers ultra-efficiently. Try the program out and see if you get a similar response to that with curl. # Use the library to perform an HTTP GET request to the URL # Import a library that allows to make HTTP request Let’s see how to do the same using a Python program This fetches location information for locations matching the query parameter san Use curl on your command line to make a REST API call to. But, what was the purpose of having an API? It was for applications to communicate with each other, right? Let’s now see how to do that programmatically. We saw how to make REST API calls using the browser. Was it included among the accept-encoding request header sent to the server? What is the data format sent by the server?Ĭheck the response encoding used. What are the HTTP methods this API endpoint supports? See if you can answer some questions based on these response headers. Here, the locations returned get filtered by the value of the query parameter, query we provide.įor every API request, the corresponding API response also contains HTTP headers that the server sends back along with the data requested. It specifies the search criteria for the resource. Query parameter: ?query=san - the part of the URL that comes after a ? character is the query parameter. Here, we are asking for the resource named location. Path: /api/location/search/ - there will be one api path for each type of resource. Root-endpoint: - defines the API provider Scheme: https - denotes the request was made using the HTTPS protocol ie, secure version of the HTTP protocol Request Body: is empty for the current request but can be used for sending additional information like a file’s content when uploading it to the server. Request Headers: eg: accept, accept-encoding - used to send additional info like the type of encoding that the requesting application (browser) supports Request Method: GET which denotes the type of HTTP request made. Let’s look at the different components of the REST API request. Use Chrome’s Developer Tools to monitor the API request made. The following video will give you a quick overview of REST API. XML is another popular format for data transfer between applications. For example, an Android app can effortlessly utilize data sent by a Node.js server. So the data format in REST is usually JSON. JSON (JavaScript Object Notation - how cryptic :| ) is a standard format that is easily "understandable" by applications and can be handled well in most languages. But, in the case of APIs, the request can be for any data (not just webpage) and the response is read by the requesting program which interprets the data. HTTP requests for webpages return HTML, CSS & JavaScript files which are rendered by the browser and displayed to the user. How an API request differs from a usual HTTP request for a webpage, is in terms of the data returned. REST APIs commonly use the HTTP protocol to send requests & receive responses. They follow a client-server model where one software program sends a request and the other responds with some data. REST APIs are those APIs which follow the guidelines set by the REST architecture. Now, these APIs have different styles, or in more formal terms - conventions and architectures about how they are used. The waiter does that for you, and that’s exactly what an API is - with the client being you, the customer and any resource that can send data, being the chef. You don’t go into a cafe and walk straight into the kitchen to tell the chef what you wanna eat. Don’t worry - no one’s gonna ask you the meaning of each word :)ĪPI stands for Application Programming Interface, and unfortunately, people will ask you the meaning of each word here. REST stands for REpresentational State Transfer.
