Step 2: Enable APIs

What you're doing in this step

Most APIs, by default, are disabled for new projects. You typically enable APIs one at a time so that your project can then access other services. To use Apigee, you must enable the following APIs for your Cloud project:

API Name	Location	Description
Apigee	`apigee.googleapis.com`	Provides communications between your project and other services and Cloud APIs.
Service Networking	`servicenetworking.googleapis.com`	Enables your managed services on internal IP addresses to connect to service consumers.
Compute Engine	`compute.googleapis.com`	Used for managing your runtime (or cluster).
Cloud Key Management Service (KMS)	`cloudkms.googleapis.com`	Manages keys and performs cryptographic operations for direct use by other cloud resources. When you use this API, you need to have a cert/key pair. You can create them now or create them later when you have to use them.

Perform the step

You cannot use the Apigee provisioning wizard to perform this step. However, you can use either the command line or the Cloud Console's UI. For more information, see Enabling APIs.

To enable the required APIs on the command line:

Log in and initialize your Cloud project if you haven't done so already.
Enable the four required APIs listed above by executing the following command:
```
gcloud services enable apigee.googleapis.com \
  servicenetworking.googleapis.com compute.googleapis.com \
  cloudkms.googleapis.com --project=$PROJECT_ID
```
Note that this command uses the $PROJECT_ID variable that you created for your Cloud environment in Step 1: Define environment variables.

Tip: Instead of using the command line, you can use the APIs & Services Dashboard in Google Cloud Console to enable the APIs.

(Optional) To check your work, list all the enabled APIs by executing the following command:

gcloud services list

The response shows all enabled services, including the APIs that you just enabled (Apigee, Service Networking, Cloud KMS, and Compute Engine). The following example shows a possible list of APIs displayed by this command:

...                                    ...
analyticsreporting.googleapis.com      Analytics Reporting API
apigee.googleapis.com                  Apigee API
appengineflex.googleapis.com           Google App Engine Flexible Environment
...                                    ...
cloudkms.googleapis.com                Cloud Key Management Service (KMS) API
compute.googleapis.com                 Compute Engine API
computescanning.googleapis.com         Compute Scanning API
...                                    ...
resourceviews.googleapis.com           Compute Engine Instance Groups API
servicenetworking.googleapis.com       Service Networking API
...                                            ...

While your list of APIs might be different than those shown above, it must include the APIs you enabled in this step. If it doesn't, try executing the previous command for each API—one at a time—to enable them. Alternatively, try using the Console to enable APIs.

For more information, see gcloud services enable.
