![]() This creates our mock server instance with a unique URL for our requests’ destination: Give the mock server a name, and stick with the defaults for all other options. ) next to your newly-forked collection and select Mock collection. ![]() While Postman allows us to create a mock server from scratch-and there are many use cases when this makes sense-we will create a mock server from the Salesforce API collection for now. Mock servers can be found within your Workspace view in Postman. By pointing your code to this mock server, you can write and test an API consumer even without having a full API implementation ready. With Postman, you can start a mock server that responds to HTTP requests of your design-quickly and without any coding required. Your collection is now configured! Mock serversĪ mock server is a lightweight server interface that responds to your API requests realistically so that you can quickly and easily get a valid response without worrying about the details. Return to the Variables tab and populate the _endpoint variable’s Current Value with the instance URL from your clipboard. Once you are redirected back to Postman, copy the instance_url parameter to your clipboard before clicking the Use Token button. Log in to Salesforce with the username and password you created when setting up your account. In the Authorization tab, click on Get New Access Token. In the Variables tab, ensure the URL parameter has the Current Value set to. Once you have a Salesforce org to work with, switch back to Postman and select the Salesforce API Collection again. (In Salesforce terminology, this is called a “sandbox” or a “scratch org”.) We’ll be working within the Salesforce development environment. In your browser, sign up for a Developer Edition account and org of your own. ![]() While it is perfectly possible to develop API code and mock servers against Salesforce without access to Salesforce, it is much easier if we have a real Salesforce org to work with. Once installed, you should see the collection appear in your workspace, and you can expand it to see the various API requests contained in the collection. Simply click the Fork button and, when prompted, give your copy a name to use locally. On the next screen, we need to fork the collection to our own local workspace. Click on its name on this list, as shown below: You’ll see many results, but the one we’re interested in is Salesforce APIs by Salesforce Developers. The easiest way to install the collection is to click on the Search Postman box at the top of the app and enter Salesforce. You can find details on how to do this step here. In order to meet the requirements of Salesforce CORS (Cross-Origin Resource Sharing) security requirements when using the Web client, you must add Postman to the list of Allowed Origins in Salesforce. For this article, we’ll use the Desktop client, but everything here is equally applicable within the Web client, with one additional step. To achieve this, we'll use one of Postman’s most powerful features-mock servers. Bringing it togetherīy using Postman’s tools for API development, we can rapidly prototype the use of the Salesforce APIs ahead of the full development of the production code that will use them. ![]() By seeing the requests and responses, it becomes much easier to develop your own code for handling these APIs. One of the most practical use cases for Postman is to explore third-party APIs, to better understand how to submit requests and work with the subsequent responses. Postman is like a powerful Swiss army knife for all things API-related-developing your own APIs, developing code that uses other APIs, or a mixture of both. We’ll look at this collection and build a mock server within Postman to simulate responses from Salesforce. There is also a Postman collection for exploring the various APIs that Salesforce exposes. Salesforce can also present your own developed code as a REST or SOAP APIs for use by other applications and services. The documentation for all the APIs is extensive. There are several Salesforce APIs available, many of which are specialized for key use cases or Salesforce products. However, for this article, we’ll focus on its capabilities as a development platform. It has several pre-built applications for key Salesforce-related business tasks. If you’re unfamiliar with Salesforce, think of it as a cloud-based development platform. In this article, we’ll show how mock servers and code snippets in Postman can help you build the core of your API-driven integration with Salesforce. Whether you’re a longtime Salesforce developer or you’re new to the platform, Postman brings you all the tools you need to streamline the Salesforce API integration process to be easier and faster.
