Generating an API key

If you have enabled authentication, then you need an API key to call a model. If you are not a collaborator on a particular project, then you cannot access the models within that project using the API key that you generate. You need to be added as a collaborator by the admin or the owner of the project to use the API key to access a model.

There are two types of API keys used in Cloudera Machine Learning:

API Key: These are used to authenticate requests to a model. You can choose the expiration period and delete them when no longer needed.
Legacy API Key: This is used in the CDSW-specific internal APIs for CLI automation. This can’t be deleted and neither does it expire. This API Key is not required when sending requests to a model.

You can generate more than one API keys to use with your model, depending on the number of clients that you are using to call the models.

Sign in to Cloudera Machine Learning.
Click Settings from the left navigation pane.
On the User Settings page, click the API Keys tab.
Select an expiry date for the Model API Key, and click Create API keys.
An API key is generated along with a Key ID.

If you do not specify an expiry date, then the generated key is active for one year from the current date, or for the duration set by the Administrator. If you specify an expiration date that exceeds the duration value set by the Administrator, you will get an error. The Administrator can set the default duration value at Admin > Security > Default API keys expiration in days
note
- The API key is private and ephemeral. Copy the key and the corresponding key ID on to a secure location for future use before refreshing or leaving the page. If you miss storing the key, then you can generate another key.
- You can delete the API keys that have expired or no longer in use. It can take up to five minutes by the system to take effect.
To test the API key:
1. Navigate to your project and click Models from the left navigation pane.
2. On the Overview page, paste the API key in the API key field that you had generated in the previous step and click Test.
  The test results, along with the HTTP response code and the Replica ID are displayed in the Results table.
  If the test fails and you see the following message, then you must get added as a collaborator on the respective project by the admin or the creator of the project:
```
"User APikey not authorized to access model": "Check APIKEY permissions or model authentication permissions"
```
