Carroll spoke at Cloudstock, the cloud developer conference being held today in San Francisco.

Apigee, Hootsuite and Model Metrics presented with Carroll, showing integrations with the Salesforce.com API.

Apigeee

The Apigee integration allows developers to view requests and responses to the API. Developers may explore the surface area, drill into errors, debug and share what they see with others. Authentication is done within Apigee so users may explore the API.

Hootsuite

Hootsuite is a Twitter client that has focused on building an app platform. In November, the company announced a new API and App Exchange. Hootsuite now integrates with Salesforce Chatter via the API. That means a user may view a Twitter stream and Chatter in the same interface.

Hootsuite is a natural fit with Chatter. Both use the same river of news style. And both have a direct tie in to the fast adoption of social technologies in enterprise and business settings.

From Hootsuite:

Model Metrics

Model Metrics extends Salesforce.com applications for mobile use. it has developed an iPad application that uses the REST API to do on-site transactions. They showed an example in which a customer can use an iPad to buy a car at a retail location. The buyer chooses the color, interior and other features of the car. The customer may use the iPad app to sign a contract using the iPad app. One signed, the information about the transaction is fed into Salesforce.com.
