SAP HANA Cloud Platform, API management provides enterprises a comprehensive solution to address all API needs, with features such as API provisioning and publishing, API discovery and consumption, security and access control, analytics and reporting, monitoring and operations and developer portal.
This SAP HANA Cloud Platform, API management repository provides samples of API proxies and applications, showcasing the capabilities of SAP HANA Cloud Platform, API management to deliver APIs protected by state-of-the-art authentication mechanisms and security policies (API Keys, basic authentication, SAML tokens, SQL threat protection) to effectively secure access to your data and services and protecting them for consumption in the cloud using quotas, spike arrests and URL rewriting.
An API Proxy is a representation of a HTTP-based service that abstracts the actual proxy endpoint properties on one end and the actual target endpoint (the endpoint that is relevant for the end user to invoke) on the other end. Additionally it includes properties that describe the policies that can be invoked on the API. Policies define a set of rules (such as enforcing security and controlling traffic) that is applied on the API. More information on supported policies is available at help.sap.com
The graphical user interface of API Management is itself API-based, permitting extensions and customizations. A sample is given in the cloudportaltemplate sub folder.

| Scenarios | Description |
|---|---|
| Basic authentication to target endpoint | Sample showcasing the generation of basic authentication header values for authentication with target endpoint. Edit the setcredential policy to provide the credentials to be used to connect to the target endpoint |
| SAML 2.0 browser profile based authentication to target endpoint | Sample showcasing the handling of SAML 2.0 browser profile based authentication to the target endpoing using JavaScript policy |
| Basic authentication for user credentials, SAML 2.0 Browser Profile Authentication for Target Endpoint | Sample showcasing the enablement of an API proxy with basic authentication. The user name and password is passed in the HTTP header. Authorization is then used to trigger the SAML 2.0 browser profile flow to the target endpoint. |
| Cross-Origin Resource Sharing (CORS) | Sample showcasing the handling of a response with a CORS header. This is helpful in scenarios where the targer server doesn't support sending CORS headers. |
| Quota | Sample showcasing the control the flow of traffic from the client to the target servers using Quota polices. It contains samples to limit the no of calls allowed per developer and also showcases quota violation handling using a HTTP 429 status as per the RFC |
| Spike Arrest | Sample showcasing the throttling of the number of incoming request processed by the API proxy. |
| SQL Threat Protection | Sample showcasing the detection of SQL threats in a query parameters and error handling via HTTP 403 Forbidden response. |
| Url Masking | Sample showcasing the masking/rewriting of the target system host, basepath and replacing it with the proxy endpoint host and base path. |
| Verify API Key | Sample showcasing the enforcement and verification of API key based access to the API Proxy. Sample contains examples to pass the API key either as header parameter or as query parameter. |
API Proxies samples are available in each sample folder under the sub folder APIProxy. The sample shared are in the API Proxy structure of SAP HCP, API management which is described in link.
- Click on the *.zip file available in each example folders and then click on the "View Raw" Link or "Download" button to download the sample.
- Import the Downloaded API Proxy zip into your SAP HCP, API management tenancy. Additional instruction for this is available in link.
Cloud Portal Template in the cloudportaltemplate sub folder contains a sample website project that uses SAP HCP, Portal Service to build a custom API Management Developer Portal. This is helpful in scenarios where API creators want to give their developers features not present in the standard API Management Developer Portal.
These samples are provided as a starting point for your implementation and are provided without any warranty or support obligations.
