# Create or extend a CAPI interface

# Create or extend a CAPI interface {#ariaid-title1}

You can create a new CAPI interface or extend an existing one by adding new
operations.

## Before you begin

* Role required: admin
* Review [Default CAPI APIs](https://servicenow-prod.fluidtopics.net/RolLhhB8~VeKVVapQD94rg "Several CAPI APIs are provided by default with the Cloud Provisioning and Governance application.") and make sure the provider and product that you want to create do not exist.
* Familiarize yourself with the cloud provider API so that you know how to create REST calls to the provider. If you are not familiar with the headers, authentication requirements, endpoint, and data that you can pass into the provider API, you cannot build your own CAPI components.

## About this task

Usually, you can use the default interfaces that are provided in the Cloud Provisioning and Governance application. To create a custom interface,
base it on an existing one that is similar.

## Procedure

1. In the Cloud Admin Portal, navigate to DesignCloud API, and then click the Interface tab.
2. Click New.
3. In the Add Cloud interface window, enter a name for the interface, a helpful description, and select the most relevant category to which the API interface should belong.  
   This example shows an interface for Azure storage:

4. In the CAPI Interface Operations related list, click New.  
   Each operation that you create corresponds to a different REST API call.
5. Provide a name for the operation that corresponds to the API you want to call in the provider.  
   For example, you can create an operation called
   CreateContainer that corresponds to the Create
   Container operation in Azure.

6. Right-click the header and select Save.
7. In the Interface Operation Parameters related list, click New.
8. Create a parameter that the operation needs as defined by the cloud provider REST API documentation.  
   If you do not know the parameters, the operation fails. In the Azure storage example, the CreateContainer operation must have the name of the container that is referred to here as
   ContainerName.

9. Click Submit.
10. Add as many parameters as you need for the operation, and then add all the operations you need.

## What to do next

[Create a CAPI API](https://servicenow-prod.fluidtopics.net/uTxEhJSV5DXMWx5odnGzMw "If the existing CAPI APIs do not integrate with the CAPI interface for a provider, you can create an API. The steps in resource blocks can call your API methods when operations are executed.")
