5. Sandbox

As an app Developer, when you learn about an API that you wish to use in your app, you’ll first want to test it out to see if the responses can be integrated to make them work with your application. DigitMarket™ API Manager provides the Sandbox environment that enables the user to do test runs on an API.

DigitMarket™ API Manager makes use of Swagger for its Sandbox UI. Swagger has a UI framework that accepts parameters and demonstrates in a Sandbox environment how an API behaves when a request is placed through its interface. Since the UI used for Sandbox testing uses standards used in Swagger Specifications as the mode for listing out resources and descriptions, the user has all the Resource descriptions that is required to start trying out APIs. The documentation that accompanies the listings allows the user to make calls from within the documentation. The API resources list presented in the Sandbox UI is extracted from JSON/YAML files (created and updated from API resources list defined by API Publishers using swagger specification) based on Swagger Specification. The JSON/YAML file contains descriptions of the REST service like Resource paths, HTTP methods, parameters of path or query, response/fault codes and types, and HTTP/fault error codes.

5.1. Configuring Sandbox Gateway

The first step for working with Sandbox requires users to configure a Sandbox Gateway. DigitMarket™ API Manager allows users to configure a Sandbox Gateway that serves as a control hub for Sandbox APIs. It decides which traffic is authorized to access the back-end services that are exposed via APIs.

  1. Navigate to the Gateways screen.
  2. Click New Gateway. The Add Gateway dialog box displays.
Add Gateway dialog

Fig. 5.1 Add Gateway dialog

  1. In the Gateway Name box, type the Sandbox Gateway name.

  2. Click the Gateway Type drop-down list to choose whether the Gateway is designated to Sandbox environment.

  3. In the URL box, enter the URL for accessing the gateway. Gateway URL is a combination of the IP address and host name for the new Gateway.

  4. In the Description box, type the description to describe the API Gateway.

  5. After entering the Gateway details, click Proceed to enter the Instance details. The Instance Details dialog box displays.

    Add Gateway Instance dialog

    Fig. 5.2 Add Gateway Instance dialog

    Note

    A Gateway can have multiple instances but one Gateway must have at least one instance. At the time of its creation, only one Gateway instance can be created.

  6. In the Gateway Instance Name box, enter the Gateway Name.

  7. In the URL box, enter the URL for accessing the main gateway instance.

  8. In the Description box, enter the description to describe the API Gateway instance.

  9. Click Save to finish adding the new Gateway and close the New Gateway dialog box. The newly added Gateway is now included to the Gateways list.

Note

Only one Sandbox Gateway can be created.

5.2. Backend Point

Under the Backend Point tab, you can find the list of all the Backend Points that are under Sandbox Gateway.

The Backend Point tab displays all the Backends along with details such as:

  • Server Name with details (Sandbox)
  • IP and Port details
  • Description
  • Mapped Filter - This option allows you to display - all Backends/only mapped Backends/only unmapped Backends.
  • Map to Gateways - Toggle button to map the unmapped Backends to the Gateway. Mapped Backends are displayed in green while unmapped Backends are displayed in red.
  • Status (Propagated or not)
  • Search box to search for a particular Backend. Enter the query in the search box and click the search icon search to display the results.
  • Repropagate - This button allows users to repropagate propagated Backends.

To map the Backend to a Gateway:

  1. Navigate to the Gateways screen.

  2. From the list of Gateways, select the Sandbox Gateway and then click the Backend Point tab. The Backend Point tab displays a list of all the Backends under this particular Gateway.

The Backend Endpoint is successfully synced to the Sandbox Gateway and no longer appears in the Changes to Backend Endpoint tab.

Next Steps: Configure API Endpoint for Sandbox.

5.5. Configuring API Endpoint for Sandbox

You can have an API Endpoint for Sandbox environment along with Production environment. The Sandbox environment is meant solely for testing the APIs with the intent of learning how to use them. You can call it the “Try-it Out” version of the Production environment. The Sandbox environment, nevertheless, has production-like data and capabilities. Sandbox allows the Consumers to try out APIs via the Sandbox Endpoints before going live and start using the APIs via the Production Endpoints. It is, however, important to know that the Usage Policies set for Sandbox environment are comparatively more rigid.

Before you begin:

It is assumed that you have a basic knowledge about how to create a REST API and add/edit API resources, configure endpoints, and manage REST API Versions and their Visibility. If not, visit these sections: Create an API and Edit an API.

To configure API Endpoints for Sandbox environment:

  1. Navigate to the REST API Configuration screen.

  2. In the REST API Configuration screen, click the Endpoints tab.

  3. In the Sandbox panel, click and drag the Sandbox toggler to the right to enable Sandbox feature. Inversely, click and drag the Sandbox toggler to the left to disable it.

    Sandbox Endpoint

    Fig. 5.15 Sandbox Endpoint

    Note

    APIs will not be propagated to Sandbox environment unless the Sandbox toggler is enabled.

  4. In the Sandbox panel, under Types of Routing, you can find two radio buttons namely, Static Routing and Dynamic Routing.

  5. In Routing, in Type of Routing, click to select the Static Routing radio button to display the Static Routing screen (Static Routing radio button is selected by default, displaying the Static Routing screen).

    Note

    Sandbox environment allows both static and dynamic routing.

  6. In Routing, in Type of Routing, click to select the Dynamic Routing radio button to display the Dynamic Routing script box. In the Script for Dynamic Routing box, type the script that will be used to dynamically route messages to the required Endpoint(s).

  7. If you have selected Static Routing, click the Select Backendpoint drop-down box to select a Real Endpoint you want to use for the Sandbox environment. The Select Backendpoint drop-down box displays all Real Endpoints added to the Sandbox environment from the Backends main menu option. In Protocol, click to select between radio buttons HTTP and HTTPS. Selecting HTTPS implies that you want to use SSL security over HTTP.

  8. The Select the Gateway you want to map drop-down displays the Sandbox Gateway configured for the publisher organization. From the Select the Gateway you want to map drop-down, choose the Sandbox Gateway to map the API. The Sandbox Gateway you select will appear at the top of the drop-down. You can remove the Sandbox Gateway by clicking the cross icon.

    Gateway to Map

    Fig. 5.16 Gateway to Map

    You can also map the API Version from the API tab of the selected Gateway. Refer API.

  1. In the Basepath box, type the base path to be used with the Sandbox Endpoint. The base path is the root path of the Real Endpoint.

    Note

    • Sandbox Basepath has “Production basepath” as the default value.
    • Sandbox Exposure Path should be configured uniquely on API Endpoint.
    • Sandbox Basepath needs to be configured same as Sandbox backend basepath.
  2. In the Exposure Path, type the exposure path to be used with the Sandbox Endpoint. The exposure base path is the root path that is visible to API consumers.

    Note

    Sandbox Exposure Path has a default value that is a combination of Publisher Sandbox Base Path and Production Exposure Path (PublisherSandboxBasePath+ProductionExposurePath) that can be modified by the user.

  3. Click the Select EndPoint security drop-down box to select security options as Pass-through.

Pass-through: When the user selects pass-through authentication as the API endpoint security, the message is allowed to pass through the Gateway without any processing or alterations and the backend server then authenticates the credentials passed in the message before sending the response back to the client.

Note

As the Sandbox environment is for testing case, Sandbox gateway doesn’t process any security authentications.

  1. Click Save as Draft to save changes.
  2. On the REST API Configuration screen, click the drop-down list and select Send for Approval(or Approve, if you have the approval rights) option to submit the API for propagation.

Note

You can add endpoints configurations to a Sandbox API only if the API is in its Draft State.

Note

An Admin user can view the REST APIs that have been enabled for propagation to Sandbox Gateway

Next Steps: Propagate the APIs that were configured to Sandbox Gateways.

5.6. Propagating APIs to Sandbox Gateways

After the Sandbox APIs are configured, it needs to be propagated to the Sandbox Gateway to be made operational.

To propagate APIS to Sandbox Gateways

  1. Navigate to the Gateway Synchronization - Changes screen.

  2. Click the Sandbox tab, and then Changes to Global Config, API, Usage Plan, Policy accordion tab to display an expanded view of the list of APIs that need propagation.

  3. In the displayed list, click to select the check box(es) corresponding to the APIs that you want to propagate to the Gateway to make them operational in the Sandbox environment.

    Gateway Sync dialog

    Fig. 5.19 Gateway Sync dialog

The API(s) is successfully synced to the Sandbox Gateway and no longer appears in the Changes to Global Config, API, Usage Plan, Policy tab.

Next Steps: Once the APIs are propagated to Sandbox, you need to create an API Pack and add the resources and other artifacts to the API Pack.

5.7. Configuring API Pack for Sandbox

Before you begin, it is assumed that:

  • The states of the APIs that you plan to add to the Pack is “Published”.
  • You have basic knowledge regarding API Pack creation and the editing process for an API Pack. If not, visit these sections: Create an API Pack and Edit an API Pack.

Once the APIs are propagated to Sandbox, you need to add the resources and other artifacts to the API Pack.

5.7.1. Add Resources from Approved or Published REST APIs to a REST API Pack

You created/edited resources for Sandbox-enabled APIs when we was in the topic: Configuring API Endpoint for Sandbox. These resources can now be added to a Pack. All the resources from Approved and Published API Versions are available for forming Pack Contents for an API Pack.

  1. Navigate to the API Packs Configuration screen.

  2. In the API Packs Configuration Screen, click the Pack Contents tab. The Pack Contents tab displays a list of all resources that have been added to the Pack. In case you are adding Pack contents to the API Pack for the first time, an empty list with the message: “There are no pack contents added yet” displays.

  5. Click to select the check boxes corresponding to Resource names that you want to add to the API Pack. Alternatively, you can click the header check box to select all resources in one go.

    Note

    By default, the Version drop-down box displays the most recent version of the Approved and Published API. To choose a different Version, click the Version drop-down box.

  6. Click Add to add the selected resources to the API Pack. The Add Resources to Pack dialog box closes. The newly added Resource(s) now displays in the Pack Contents list.

  7. Click Save as Draft to save the newly added Pack Contents. A notification message “API Pack details were updated successfully” displays indicating that the newly added Pack contents are saved successfully.

Note

The Add Resources to Pack option is enabled and hence available for API Pack versions that are in Draft State.

5.7.2. View and modify a Sandbox Plan

A Sandbox Plan is a set of policies that defines the level of Sandbox service that is offered to the subscriber. If a Sandbox-enabled API is added to a pack, a Sandbox plan is created by default for that API pack. You can also add a regular usage plan apart from the Sandbox plan for an API Pack. Vist this section for more details: Create a Usage Plan.

  1. Navigating to the API Packs screen.

  2. In the API Packs Configuration screen, click the Usage Plans tab. Sandbox plan in draft state is displayed by default.

    Note

    Sandbox plan will change into draft state automatically while updating/inserting/deleting the API Pack contents of sandbox-enabled API version resources.

    Note

Note

All the Plans (including the Sandbox plan) under an API pack have to be in the Approved or Published State for you to be able to send the Pack for approval.

Once the Sandbox Plan is approved, if Automatic Approval Workflow is not enabled, the Sandbox Plan’s State changes from Submitted for Approval to Approved. If Automatic Approval Workflow is enabled, the Sandbox Plan’s State changes from Draft to Approved. An Approved Sandbox Plan displays in the Gateway Sync page, from where it needs to be propagated and made operational in the Gateway. Once the Plan is propagated to the Gateway, the State of the Plan changes to the Published state. The Published state of the Plan (and other plans in the case of Usage-based strategy) allows you to send the Pack for approval.

5.7.4. Send an API Pack for Approval for Sandbox

You need to publish the Sandbox plan and all the Usage Plans that have been created within a API Pack for you to be able to publish the API Pack. An API Pack is restricted from being send for approval if Sandbox/Usage Plan remains in the Draft or Approved State, which means that all the Plans under the Pack must be in the Published State.

Next Steps: Test using Sandbox.

5.18. Test using Sandbox

Developers use the Sandbox environment to test and find how their Apps could be integrated with the APIs that they want to use. The Sandbox allows you to make a sample API call from within the documentation page. This will help the developers to choose the appropriate subscription for their API plans as it allows them to know the number of APIs in a plan and how to consume those APIs.

The Sandbox uses industry-standard Swagger to describe the REST API service, Resource name, Resource Description, Resource methods, parameters (covering parameter types: form/path/query) - whether parameters are required or are optional, Expected Response Content type (JSON or XML), Response message, HTTP response code or Error code depending on whether the response was a success or failure.

To learn more about Sandbox environment, refer ‘Sandbox’ under Developer Portal.

Given below is a typical workflow that you can use as a checklist prior to and while using Sandbox:

  • Create an Application profile
  • Generate Access Tokens
  • Invoke the API using the Try-it feature
  • Generate Client code with SDK
  • Develop Apps and integrate them with Sandbox Endpoints
  • Perform integration tests with data provided in Sandbox
  • Validate token Expiry scenarios and simulate errors

To invoke an API using the Try it feature:

  1. Log in to the Developer portal.

  2. Navigate to API Packs Details screen.

    The API Pack Details page displays.

    API Pack Details

    Fig. 5.78 API Pack Details

  3. Click Try it tryit. The API Pack Sandbox page displays with the API Pack Resource list in a Swagger UI.

    Note

    Some of the APIs might require authorization. Scopes are used to grant an application different levels of access to data on behalf of the end user. Each API may declare one or more scopes. You can select the scope that you want to grant to Swagger UI.

  4. Click the right / down icon to toggle between showing/hiding the Resource details - Resource names, methods, parameters and other details.

    Resource details

    Fig. 5.79 Resource details

  5. Click the resource method to display an expanded view.

    Expanded view of Resources

    Fig. 5.80 List view of Resources

  6. Click Try it Out.

  7. In the mandatory parameter fields, type the required parameters and click Execute to test invoke the API. Response message will be displayed based on the value of the parameters entered.

Note

Users must keep in mind the points listed below while using the Sandbox feature to test the APIs:

  • Sandbox “Try it” feature shows only REST resources configured using swagger specifications file.
  • Sandbox “Try it” feature, doesn’t support storing transaction details and analytics.
  • Sandbox doesn’t support auto propagation to linked plans for API propagation.
  • Plan level security policies will not be applicable.
  • Plan defined with oAuth security policy doesn’t validate the access token on Sandbox.
  • Sandbox doesn’t support rollback functionality.
  • Sandbox doesn’t support two-way SSL between Portal and Nginx.
  • All service calls to the Sandbox backend must implement URL encoding.
  • IP Black listing, White listing and MCT limit are not applicable for sandbox.
  • URI encoding containing any of the following characters will not work: # [ ] { } ~ | %
  • Only the following special characters are tested as working for path and query parameters: @ ! # $ % ^ & * - _ = + [] {} | : ; , . `
  • Only the following special characters are tested as working for Resource name - @ $ space ! * - _ = + . ,
  • Only one Sandbox Gateway is allowed per publisher account.
  • Sandbox plan can support only subscription-key authentication model.
