Step 4: Test your API

You're viewing Apigee and Apigee hybrid documentation.
View Apigee Edge documentation.

To test the deployed helloworld API, click the Terminal tab in Apigee in VS Code and enter the following curl call:

curl 0:8998/helloworld

Note: The examples in this section use 0 for the host value and 8998 for the port value. You can configure the port values, as described in Managing the Apigee Emulator. If you get an error when using 0, substitute localhost for the 0:

curl localhost:8998/helloworld

The following error message is displayed:

Calling API in terminal tab and getting an authorization error

Since you enabled API key based authentication when creating the API proxy, you need to pass an API key using the apikey query parameter when calling the API.

To obtain an API key, you need to create a test bundle and configure the following test resources:

API product used to bundle the API and make it available to developers
Developer that will create an app to access the API
Developer app that will enable access to the API using an API key

Build and export test resources, obtain the API key, and re-test your API.

Create a test bundle:
1. Position your cursor over the tests folder in the Apigee section and click .
  
  The Create test bundle wizard opens.
2. Enter mytestbundle for the test bundle name and press Enter.
  The test bundle is created.
3. Expand the mytestbundle folder in the Apigee section to view its contents.
Configure the API product test resource:
1. Position your cursor over the products.json file in the Apigee section and click .
  
  The Create API product wizard opens.
2. Enter myproduct for the name of the API product and press Enter to confirm and proceed.
3. Enter myproduct for the description of the API product and press Enter to confirm and proceed.
4. Select helloworld to add the API proxy to the API product and click OK.
  The products.json file is opened in the editor with the new API product configured, as shown below:
```
[
  {
    "attributes": [
      {
        "name": "sample_attribute_0",
        "value": "sample_attribute_value_0"
      }
    ],
    "scopes": [],
    "environments": [],
    "apiResources": [
      "/",
      "/*",
      "/**"
    ],
    "quota": "100",
    "quotaInterval": "1",
    "quotaTimeUnit": "minute",
    "name": "myproduct",
    "displayName": "myproduct",
    "proxies": [
      "helloworld"
    ]
  }
]
```
Configure the developer test resource:
1. Position your cursor over the developers.json file in the Apigee section and click .
  
  The Create developer wizard opens.
2. Enter the following values at the prompts and press Enter to confirm and proceed:
  - Developer email: ahamilton@example.com
  - Username: ahamilton
  - First name: Alex
  - Last name: Hamilton
  The developers.json file is opened in the editor with the new developer configured, as shown below:
```
[
  {
    "attributes": [
      {
        "name": "sample_attribute_0",
        "value": "sample_attribute_value_0"
      }
    ],
    "email": "ahamilton@example.com",
    "userName": "ahamilton",
    "firstName": "Alex",
    "lastName": "Hamilton"
  }
]
```
Configure the developer app test resource:
1. Position your cursor over the developerapps.json file in the Apigee section and click .
  
  The Create developer app wizard opens.
2. Select ahamilton@example.com as the owner of the app.
3. Enter the following values at the next set of prompts and press Enter to confirm and proceed:
  - App name: myapp
  - Description: myapp
  - Callback URL: Leave blank
4. Select myproduct to add it to the app and click OK.
5. Select never for the expiry value.
  The developerapps.json file is opened in the editor with the new app configured, as shown below:
```
[
  {
    "attributes": [
      {
        "name": "sample_attribute_0",
        "value": "sample_attribute_value_0"
      }
    ],
    "developerEmail": "ahamilton@example.com",
    "name": "myapp",
    "displayName": "myapp",
    "callbackUrl": "",
    "apiProducts": [
      "myproduct"
    ],
    "expiryType": "never"
  }
]
```
Export the test resources to the Apigee Emulator.
In the Apigee section, position the cursor over the mytestbundle test bundle and click .

Note:If multiple containers for the Apigee Emulator are running, you are prompted to select the container to which you want to deploy the environment.

The active test resources appears in the Apigee Emulators section, as shown in the following figure.
In the Apigee Emulators section, under Active test resources, click Active developer apps.
The active developer apps configuration file is opened in the editor. The file contains credentials for myproduct, as highlighted in the following figure.
Copy the consumerKey value (without the quotes) for the myproduct API product.
Pass the API key in your curl call using the apikey query parameter, as follows:
```
curl 0:8998/helloworld?apikey=ZQA5euYtNeJ7ZCGCJMpvd6F2BZOmxOzY
```
The following response is returned:
```
Hello, Guest!
```

Congratulations! You've successfully run an API in your local environment.

In the next step, you'll learn how to change the target endpoint.
