Create an API walkthrough video without hitting record
Point Flowcase at your API console or dev dashboard, describe the flow, and get a clean, captioned MP4 rendered in the cloud.
Developers do not watch a forty-minute screen capture of someone fumbling through a settings page. They want the exact path: generate a key, fire a request, read the response, confirm the webhook landed. Flowcase records that path for you and renders it as a video clean enough to ship on your docs site, your changelog, or a launch post.
You do not install anything or stage a perfect take. You give Flowcase the URL and the steps. It drives the browser, captures the run, and edits it into paced scenes with auto-zoom and captions.
Re-render on every API change
When an endpoint or screen changes, regenerate the same walkthrough against the new UI instead of re-shooting it.
Auto-zoom on the right detail
The camera eases into each request, field, and response key, then back out, so viewers never hunt for what matters.
Real data, no password shared
Save a login session once on Connections and Flowcase records as your account without ever seeing your credentials.
Captions and clean cursor motion
Auto-generated captions and smooth, eased cursor movement come standard, so mute-watching devs still follow every step.
How a walkthrough gets built
Start with your URL: the API playground, the OpenAPI explorer, your project dashboard, a CLI running in a web terminal. Then describe the flow in plain English, like 'create a new project, generate an API key, send a test request, and show the 200 response.' If you need exact control, give scripted steps instead: click this button, type this payload, wait for that row to appear.
Flowcase runs the flow as a real session in the cloud. It captures the screen, then a director pass groups the raw clicks into named scenes with timing and importance, so key creation gets room to breathe and the boilerplate moves quickly.
The result renders as an MP4 up to 4K. Drop it in your docs, embed it in a README, or attach it to a release.
Why this beats recording it yourself
A manual screen recording means clearing notifications, resetting test data, redoing the take when you misclick, then cutting it in an editor and re-recording the parts where you talked over yourself. Every API change means doing it all again.
Flowcase removes the take. Because the run is defined by a goal or a script, you regenerate the same video against the new UI in minutes when your endpoint changes. The camera also does work no hand-held recording does: it eases into each click and field, then pulls back out, so a viewer always knows which header or response key you mean.
Example flows developers ship
A quickstart for your REST API: register an app, copy the bearer token, run the first authenticated GET, and show the JSON come back. A dashboard tour for a new analytics feature: filter events, build a chart, save the view. A webhook walkthrough: add an endpoint, trigger a test event, and watch the delivery log flip to succeeded.
For anything behind a login, save a session once on the Connections page. Flowcase then records as your account, so the video shows real project names and live data, and your password is never exposed to the system.
From flow to shareable link
Captions are generated automatically, which matters for developer content watched on mute in a feed or a Slack channel. Cursor motion is smoothed and eased, so fast clicks read as deliberate moves rather than jitter.
Pick your resolution up to 4K, render, and download the MP4 or share it. No timeline scrubbing, no export presets to guess at.
Frequently asked questions
- What makes a good API walkthrough video?
- Show one path end to end with no dead air: authenticate, make the call, read the response. Flowcase handles the pacing by grouping clicks into named scenes through a director pass, zooming into each step, and adding captions, so the video stays tight and the important moments get the most screen time.
- Can it record a flow that requires logging in?
- Yes. Save a login session once on the Connections page, and Flowcase records as your account so the walkthrough shows live data and real project names. Your password is never exposed to Flowcase during capture.
- Do I have to write exact steps, or can it figure out the flow?
- Either way works. Describe the goal in plain English and the AI agent plans the clicks and typing for you, or hand it scripted steps when you need an exact, repeatable path: click this, type that, confirm this result.
- What resolution can I export for docs and changelogs?
- Cloud rendering goes up to 4K. The Free plan renders 1080p, Starter does 1080p, Pro does 1440p, and Scale does 4K. Higher resolutions look sharp embedded in documentation or played full screen in a launch post.
- Will the video break when our dashboard or API changes?
- If a screen or endpoint changes, you do not re-shoot. Update the flow if needed and re-render against the new UI, which keeps your walkthroughs current without booking time to record again.
- Can I show terminal or CLI output in the walkthrough?
- If your CLI runs in a web terminal or your output shows in a browser-based console, Flowcase captures it like any other page. It records what loads in the browser or cloud, so anything you can reach at a URL can be part of the video.
