Colleagues evaluating the product may first need to see where the API fits. Follow one supported request and response to give them that introduction without trying to replace an integration guide. ![Programming code on a computer screen](https://caprivideo.com/content/images/code.jpg) *Illustrative stock photo: [Daniil Komov / Pexels](https://www.pexels.com/photo/close-up-of-computer-screen-with-code-displayed-34803966/).

Follow a sample request through supported processing and a documented response. Keep credentials fictional and clearly marked for demonstration. A brief error or exception path can be more informative than implying that every request always succeeds in the same way. ## Prepare a consistent demo Use current documentation, a working demo and confirmed interface details, with a technical reviewer for the example. Use fictional demo data and record the screens and product version shown. Check who acts in each scene and what the screen actually confirms. ![Server racks and cabling in a data center](https://caprivideo.com/content/images/server.jpg) *Illustrative stock photo: [Brett Sayles / Pexels](https://www.pexels.com/photo/server-racks-on-data-center-5480781/). [Pexels License](https://www.pexels.com/license/).* ## Try it before the next demo Link the overview to the relevant documentation. Ask which system sends the request and what comes back. If viewers recall only connected logos, add the missing technical detail. The film should help them find the right reference material while leaving the interface contract and integration work to the documentation. ## Related reading - [Show what someone can do with your software](https://caprivideo.com/guides/saas-video-production) - [Connect the sensor reading to the next action](https://caprivideo.com/industries/software-saas/iot-platform-explainer-videos) ## Related pages - [Industry group: Software & apps](https://caprivideo.com/industries/software-saas) - [A little more background: Show what someone can do with your software](https://caprivideo.com/guides/saas-video-production) - [Connect the sensor reading to the next action](https://caprivideo.com/industries/software-saas/iot-platform-explainer-videos): Trace one supported IoT signal into the platform while keeping monitoring and machine control distinct. - [Make it clear when an app booking is confirmed](https://caprivideo.com/industries/software-saas/app-explainer-videos): Follow one user role through request, response and confirmation, with payment kept separate where the product requires it. - [Explain where the money goes](https://caprivideo.com/industries/software-saas/payment-provider-explainer-videos): Show merchants how a payment runs, when the money arrives and how integration works. - [Show what happens to a new lead in your CRM](https://caprivideo.com/industries/software-saas/crm-explainer-videos): Follow the same fictional contact through intake, assignment and the next supported sales action. - [Follow one order through your ERP](https://caprivideo.com/industries/software-saas/erp-explainer-videos): Connect order entry, inventory and invoicing while showing where people review information and where systems connect. - [Show a working day in practice-management software](https://caprivideo.com/industries/software-saas/practice-software-explainer-videos): An appointment can connect booking, staff roles and administrative tasks without turning the demonstration into a clinical claim. ## See your offer as a video We create a free watermarked video for your business from your website.
