Create and Publish an API

API creation is the process of linking an existing backend API implementation to the API Publisher so that you can manage and monitor the API's lifecycle, documentation, security, community, and subscriptions. Alternatively, you can provide the API implementation in-line in the API Publisher itself.

The steps below shows you how to create a new API.

1. Log in to the API Publisher.
   https://<hostname>:9443/publisher
2. In the APIS menu, click Add New API.
   
3. Select Design New REST API and click Start Creating.
   

4. Give the information in the table below and click Add to add the resource.

   Field		Sample value
   Name		PhoneVerification
   Context		/phoneverify   Tip: You can define the API's version as a parameter of its context by adding the {version} into the context. For example, {version}/phoneverify. The API Manager assigns the actual version of the API to the {version} parameter internally. For example, https://localhost:8243/1.0.0/phoneverify. Note that the version appears before the context, allowing you to group your APIs based on the versions.
   Version		1.0.0
   Visibility		Public
   Resources	URL pattern	CheckPhoneNumber
   	Request types	GET, POST

   

5. After you add the resource, click it's GET method to expand it and update the Produces to application/xml and Consumes to application/json. Next, add the following parameters. You use these parameters to invoke the API using our integrated API Console, which is explained in later tutorials. 
   Once done, click Next: Implement > .

   Parameter Name	Description	Parameter Type	Data Type	Required
   PhoneNumber	Give the phone number to be validated	Query	String	True
   LicenseKey	Give the license key as 0 for testing purpose	Query	String	True

   
   Alternatively, click Save to save all the changes made to the API. You can come back later to edit it further by selecting the API and clicking on Edit. For details about the states of the API see Manage the API Lifecycle.

6. Click the Managed API option.
   

7. The Implement tab opens. Enter the information in the table below.

   Field	Sample value
   Endpoint type	HTTP/REST endpoint
   Production endpoint	This sample service has two operations as CheckPhoneNumber and CheckPhoneNumbers. Let's use CheckPhoneNumber here. http://ws.cdyne.com/phoneverify/phoneverify.asmx To verify the URL, click the Test button next to it.
   Sandbox endpoint	This sample service has two operations as CheckPhoneNumber and CheckPhoneNumbers. Let's use CheckPhoneNumber here. http://ws.cdyne.com/phoneverify/phoneverify.asmx To verify the URL, click the Test button next to it.

   

8. Click Next: Manage > and enter the information in the table below.

   Field	Sample value	Description
   Subscription Tiers	Select all	The API can be available at different levels of service. They allow you to limit the number of successful hits to an API during a given period of time.

   

9. Click Save & Publish.
   This publishes the API that you just created to the API Store so that subscribers can use it. You have created an API.
