The API is accessible at http://localhost:4502/api/screens.json. Acceptable reasons to break from this rule are: Well-known exceptions, as described below. The JCR (Java Content Repository) 2.0 APIs is part of a specification for JCR implementations (in the case of AEM, Apache Jackrabbit Oak). When a change is detected, it will build an AEM Package and upload it to your AEM Server via a Restful API. Restful Web Services is a lightweight, maintainable, and scalable service that is built on the REST architecture. The following are common exceptions to the rules defined above. An AEM page that uses a Restful request to calculate the distance between two cities. The API is accessible at http://localhost:4502/api/screens.json. In REST Architecture everything is a resource. REST APIs enable you to develop any kind of web application having all possible CRUD (create, retrieve, update, delete) operations. Note that this is not a ValueMap, the 2nd parameter (default value, and auto-type casting) is not supported. OSGi application container abstractions such as services and (OSGi) components. Simply create Sling Servlets that can be accessed using an HTTP GET or HTTP POST. I want to create REST call in AEM E.g. In JSON, just three types of data exist: ... Handling Sling Schedulers in AEM … Always use PageManager to create pages as it takes a Page Template, is required to properly define and initialize Pages in AEM. Introduction to RESTFul web services A web service is a collection of open protocols and standards used for exchanging data between applications or systems. JCR-SQL2 and XPath can be executed directly via Sling and JCR APIs, returning results a Sling Resources or JCR Nodes, respectively. To answer you first part of the question: You need to invoke the API from JSP/Sightly/JS using Ajex or you can achieve it from OSGI custom Service/Component. RESTful web services: RESTful web services are basically REST based architecture web services. If you  want to get page data, you can use default sling Get servlets. RESTful Web Services is a module that takes advantage of Entity API to provide you the information of all entity types, be it nodes, comments, taxonomy terms or your users. Despite this robust API, it is rare they’re preferred over the higher level AEM and Sling abstractions. I am able to test the Servlet with admin credentials . For example, this URI, /IBM/director/rest/resources/PowerOutletGroup, will return a resource that contains the list of … And what sort of Read / Write access  levels should be assigned to the user. Condition is, when REST call in invoked   E,g, localhost:4502/content/a/b_jcr_content.getData.json (POST). AEM supports multiple query languages. This can only write to the immediate node (relative property paths are not supported). Copyright © 2020 Adobe. For testing purposes - try removing credentials to make sure that the POST servlet works - once we know if works - then we can figure out why authentication is not working. Posted by Naveen | 6:00 AM | In this article , I am going to write about how to consume data from a third-party Restful Webservice in Adobe Experience Manager. AEM will get all POST data and create a predefined node structure. Adapting a resource to a Page requires the resource itself to be the cq:Page node. AEM Forms connected with REST API using FDM. and serve that data as the servlet's response - then you need to write your own Servlets. When creating higher level abstractions (AEM Pages, Assets, Tags, etc.) 1) Content Services 2) Assets HTTP API 3) Custom Sling Model Exporter The Assets HTTP API exposes folders and assets from AEM to external world over Restful HTTP APIs. You can find theinstallation instructions on the .NET Core Downloadspage. Copyright © 2020 Adobe. This REST service will be invoked from an external system (outside AEM).

RESTful API focuses more on how to expose these microservices while keeping them decoupled. However - you can easily hit the AEM Servlet from other apps that support Restful operations, Please refer to these post for detail answers:-. In its basic form, a REST API is a URI that can perform a single operation. use the methods provided by their respective Managers. However - if you want to get non-page data - for example - a list of DAM assets in XML or pull data from a 3rd party database. The Asset API provides convenient methods for reading properties from the [dam:Asset]/jcr:content/metadata node. AEM Sync will look for and detect jcr_root folders, and begin watching all the folders and files in them for changes using fs.watch. or Sling Resource APIs as they provide better abstractions. RESTful API: A RESTful API is an application program interface ( API ) that uses HTTP requests to GET, PUT, POST and DELETE data. Since AEM 6.2, the Sling ResourceResolver is AutoClosable in a try-with-resources statement. com.day.cq contains “original” APIs. Adobe Experience Manager (AEM) is built on a rich open-source software stack that exposes many Java APIs for use during development. It makes it easier for these smaller independent applications to communicate with each other. ResourceResolvers can be must be manually closed in a finally block, if the auto-closing technique shown above cannot be used. Data and content abstractions such as node, properties and sessions. would they have to use credentials to fire the rest call along with port number ? Adapting a resource to an Asset requires the resource itself to be the dam:Asset node. Using the AEM APIs ensures consistent behavior between AEM the product, and customizations and extensions to AEM. These APIs are supported and should not be avoided, unless com.adobe.cq or com.adobe.granite provide a (newer) alternative. The two functions are often tied together in single solutions, but the easiest way to divide authorization and authentication is to ask: what do they actually state or prove about me? What are the data sources ? Creating and removing resources via ResourceResolver’s create/move/copy/delete methods. pageManager.getContainingPage(..) resolves any resource under the cq:Page to the Page object by walking up the tree as needed. However, you can use whatever tools you arecomfortable with. AEM APIs provide abstractions and functionality specific to productized use cases. And following are my properties for servlet : Try giving the user that you use to authenticate the HTTP request read and write permissions required to access  the part of the JCR that you want to modify. Authenticationis when an entity proves an identity. These snippets also illustrate how to move from less preferred APIs to more preferred APIs. What are the data sources ? For example, AEM’s PageManager and Page APIs provide abstractions for cq:Page nodes in AEM that represent web pages. REST and resource-based abstractions such as resources, value maps, and HTTP requests. The best place for the newbies to start and a good refresher for the experienced AEM developers. AEM APIs have an intra-package preference, identified by the following Java packages, in order of preference: com.adobe.cq supports product use cases whereas com.adobe.granite supports cross-product platform use-cases, such as workflow or tasks (which are used across products: AEM Assets, Sites, etc.). AEM QueryBuilder API leaks a ResourceResolver object. We know that AEM Supports 3 ways of headless delivery in JSON format. In the Java Swing article - notice the properties that removes authentication. This order is a general rule, meaning exceptions exist. Lets use them rather than building an additional API layer which would put extra load on AEM. 1. That is very easy to do. AEM’s OSGi implementation, Apache Felix, provides several of its own APIs as well. In this example - the client is a Java Desktop app. OSGi annotations for declaring OSGi services and components. Use Sling’s ModifiableValueMap to write properties to nodes. The preferred API is AEM Query Builder, which is the highest level abstraction and provides a robust API for constructing, executing and retrieving results for queries, and provides the following: Simple, parameterized query construction (query params modeled as a Map), OOTB predicates supporting common query requirements, Extensible API, allowing for the development of custom query predicates. Then after parsing the response data you can save it in JCR using JCR API. Another question : how would external system can invoke the call to AEM  Author instance , would they have to use credentials to fire the rest call along with port number ? While these nodes are available via Sling APIs as Resources, and JCR APIs as Nodes, AEM’s APIs provide abstractions for common use cases. Accessing JCR nodes as Sling Resources and accessing their data via ValueMaps. New abstractions such as Content Fragments and Experience Fragments are built out in the com.adobe.cq space rather than com.day.cq described below. This article explores the major APIs and when and why they should be used.
