# Accessing Entando APIs

# Overview

Entando includes the Swagger UI in a quickstart environment and is reachable at /entando-de-app/api/swagger-ui.html:

http://[your-host-name]/entando-de-app/api/swagger-ui.html

# Enable or disable the Swagger UI in a running container

The Swagger UI can be enabled or disabled in a running container by modifying the SPRING_PROFILES_ACTIVE environment variable for the entando-de-app container.

  1. Edit the deployment. The name may be different outside of a quickstart environment.
sudo kubectl -n entando edit deployment/quickstart-server-deployment

  1. (Optional) Scale the deployment spec.replicas to 0 before updating the deployment. This is necessary if you're using an in-memory database, e.g. the default quickstart configuration, and will prevent database errors that can happen on an immediate restart after the profile is changed. Save the deployment to apply the change.

  2. Find the entando-de-app env variables section under spec.template.spec.containers.env[image: entando-de-app]

4a. To enable the swagger UI, add the SPRING_PROFILES_ACTIVE environment variable, if it's missing, or add swagger to its comma-delimited list.

        - name: SPRING_PROFILES_ACTIVE
          value: default,swagger

4b. To disable the swagger UI, remove swagger from the value.

  1. (Optional) Reset the deployment spec.replicas back to 1.

  2. Save the deployment to apply the change.

# How to find your client secret

You'll need your client credentials to execute the Entando APIs.

  1. Login into your Keycloak instance

  2. Go to Administration → Clients

  3. Select the desired client (e.g. in a quickstart environment this is quickstart-server)

  4. Click on the Credentials tab to get the secret

# Setup in local environment

You may prefer to run a local standalone Entando application for some tasks. You'll need Java 11, maven, and Keycloak for authentication. See these instructions (opens new window) to setup a standalone Keycloak.

# Configure Keycloak

Configure your Keycloak client in order to support Swagger UI. A quickstart environment has this pre-configured.

  1. Login to your Keycloak instance

  2. Access the Administration console

  3. Click on Clients on the left bar and select your client (e.g. quickstart-server)

  4. Update the following values under Settings:

    • Set Valid Redirect URIs to http://localhost:[your port]/entando-de-app/* or * to allow all redirect URIs.
    • Set Web Origins to http://localhost:[your port] or * to accept all origins.

# Start the Entando Application

  1. Clone the Entando reference application:

    git clone https://github.com/entando/entando-de-app

  2. Start the application with the following options:

    • Enable the Swagger profile via -Dspring.profiles.active=swagger
    • Enable the Keycloak profile via -Pkeycloak
    • Configure the application connection to Keycloak itself. For simplicity this uses the same client credentials you'll use to try out the APIs.
      • Set -Dkeycloak.auth.url to your Keycloak endpoint (including /auth), e.g. -Dkeycloak.auth.url=http://my-keycloak-server/auth
      • Set -Dkeycloak.client.id to your client id, e.g. -Dkeycloak.client.id=quickstart-server
      • Set -Dkeycloak.client.secret to your client secret, e.g. -Dkeycloak.client.secret=my-secret. See How to find your client secret above.
    • (Optional) Set-Djetty.port=8085 if the default port 8080 is already in use.
    • (Optional) To skip the docker steps (or if you don't have docker installed/running), add -DskipDocker=true

    Here's a full example:

    mvn clean package jetty:run-war -Pjetty-local -Pderby -Pkeycloak -Dspring.profiles.active=swagger -Djetty.port=8085 -Dorg.slf4j.simpleLogger.log.org.eclipse.jetty.annotations.AnnotationParser=error -Dkeycloak.auth.url=http://my-keycloak-host/auth -Dkeycloak.client.id=quickstart-server -Dkeycloak.client.secret=my-client-secret -DskipDocker=true

  3. Wait for the application to start.

    [INFO] Started ServerConnector@1355c8be{HTTP/1.1, (http/1.1)}{0.0.0.0:8085}
[INFO] Started @66257ms
[INFO] Started Jetty Server

  4. Navigate to the Swagger UI in a browser at /entando-de-app/api/swagger-ui.html

     http://localhost:[your port]/entando-de-app/api/swagger-ui.html

# APIs Overview

The Entando core exposes REST APIs for every action that can be taken in the App Builder environment. For example, you can use these APIs to create pages, create page templates or to add widgets to pages. The APIs can be used to support automation, testing, or integrations with external systems.

# API structure

All of the APIs share a common top level structure. Each response will contain a top level entry for errors, metadata, and payload.

The errors will always contain code and a message string indicating an error condition in the request. The metadata section is used for paging, sorting, filtering and data that is distinct from the body. The body of each response is included in the payload section of the response and varies according to each API.

# Models

All of the model classes returned by the Entando core are annotated so that the model definition is included in the Swagger documentation. At the bottom of the Swagger page all of the model classes returned by the API endpoints can be found.

# Tutorial

  1. Access your application Swagger UI as discussed above

  2. Click on the Authorize button in the upper right corner

  3. Enter the client id and client secret in the open window and click Authorize

  4. If you are redirected to the Entando login page, log in with your credentials (default are admin/adminadmin)

  5. You will be redirected to the Swagger UI page, now authenticated

  6. Use the Try it out button on the APIs

    • Scroll to widget-controller

    • Select the blue GET row

    • Select Try it out

    • Look at the results in the window. You should see a Server response with Code 200 and full response body.
