RapidAPI Teams is a collaborative platform that enables organizations to share internal API documentation and testing with team members. To create an organization account, you need to fill out a registration form, specify an organization name, and invite team members to join it. Once the organization is created, you can add an internal API for use in your organization. The API can be defined using a "Design First" or "Code First" approach, with documentation that can be shared with team members. Team members can access the API's Endpoints page, edit its settings, and test it using the auto-generated test interface. This allows teams to collaborate on API development and testing, while maintaining control over sensitive data sources.
