API Demo Video: Showcase Developer Products

Why API Videos Matter

Developers prefer to self-serve. They evaluate tools through documentation, not sales calls. But reading API docs is time-consuming.

Video demos let developers quickly understand what your API does, how it works, and whether it's worth exploring further.

Understanding Your Developer Audience

What Developers Want

Quick answers to:

  • What does this API do?
  • How hard is implementation?
  • What's the learning curve?
  • Does it solve my problem?

They don't want:

  • Marketing fluff
  • Unnecessary animations
  • Slow pacing
  • Vague explanations

Developer Content Preferences

Effective approaches:

  • Code examples first
  • Real terminal output
  • Actual API calls
  • Practical use cases

Avoid:

  • Slideshow explanations
  • Abstract diagrams without code
  • Scripted corporate tone
  • Oversimplified examples

Types of API Demo Videos

API Overview (2-3 minutes)

Purpose: Quick introduction for evaluation

Content:

  • What the API does
  • Key capabilities
  • Quick code example
  • Where to start

Best for: Homepage, documentation landing, discovery

Quick Start Tutorial (5-10 minutes)

Purpose: Get developers to first success

Content:

  • Account/key setup
  • First API call
  • Basic workflow
  • Next steps

Best for: Getting started docs, onboarding

Feature Deep Dive (10-20 minutes)

Purpose: Comprehensive feature education

Content:

  • Specific endpoint or feature
  • Multiple use cases
  • Edge cases
  • Best practices

Best for: Reference documentation, advanced users

Integration Tutorial (15-30 minutes)

Purpose: Show integration with popular tools

Content:

  • Integration setup
  • Configuration
  • Common patterns
  • Troubleshooting

Best for: Partner/integration pages, search

Recording API Demos

Environment Setup

Terminal preparation:

  • Clean terminal history
  • Appropriate font size (16-18pt)
  • High contrast color scheme
  • Relevant environment variables set

Code editor setup:

  • Clean workspace
  • File structure visible
  • Appropriate syntax highlighting
  • Extensions/plugins hidden if distracting

Screen setup:

  • 1920x1080 resolution
  • Relevant windows only
  • Browser with API docs if needed
  • API testing tool ready (Postman, curl)

Recording Best Practices

Pacing:

  • Type at readable speed
  • Pause after commands
  • Explain before executing
  • Give time to process output

Code visibility:

  • Use large font sizes
  • Highlight important lines
  • Split screen for code + result
  • Zoom on key sections

Narration style:

  • Technical but accessible
  • Explain the "why" not just "what"
  • Acknowledge complexity honestly
  • Point out common pitfalls

Common Recording Approaches

Live coding:

Actually write and run code during recording

  • More authentic
  • Shows real workflow
  • Mistakes can be edited

Pre-written code:

Reveal and explain pre-prepared code

  • Faster, cleaner
  • Easier to polish
  • Less authentic feel

Hybrid:

Pre-written structure, live execution

  • Best of both worlds
  • Run actual API calls
  • Controlled but genuine

Structuring API Demo Content

The Developer-Friendly Formula

Opening (30 seconds):

  • State what you're building
  • Mention prerequisites
  • Show end result first

Setup (1-2 minutes):

  • Installation/authentication
  • Environment requirements
  • Quick verification

Main Demo (variable):

  • Write/show code
  • Execute and explain
  • Show results
  • Handle errors gracefully

Wrap-up (30 seconds):

  • Recap what was built
  • Point to next resources
  • Invite questions/feedback

Code Example Structure

Effective pattern:

  1. Show the goal
  2. Explain the approach
  3. Write/reveal the code
  4. Execute and show output
  5. Explain the result
  6. Mention variations

API Video Best Practices

Technical Accuracy

Essential:

  • Use current API version
  • Show actual responses
  • Include realistic data
  • Acknowledge limitations

Testing:

  • Run all code before recording
  • Verify outputs match narration
  • Test with fresh accounts
  • Check for deprecation

Accessibility

Include:

  • Closed captions
  • Transcript with code
  • Chapter markers
  • Links to written docs

Maintenance

Plan for updates:

  • Document recording setup
  • Note API version used
  • Create reusable segments
  • Track outdated content

Developer-Focused Distribution

Documentation Integration

Embed videos in:

  • Getting started guides
  • API reference pages
  • Tutorial sections
  • Troubleshooting guides

Developer Platforms

Share on:

  • YouTube (developer channels)
  • Developer blogs
  • Stack Overflow references
  • Technical communities

Developer Events

Use for:

  • Conference presentations
  • Webinar content
  • Workshop materials
  • Demo days

Measuring API Video Success

Engagement Metrics

Watch behavior:

  • Watch time
  • Completion rate
  • Rewatch sections
  • Speed preferences

Developer signals:

  • Documentation visits after video
  • API key signups
  • First API call timing
  • Tutorial completion

Feedback Channels

Collect input:

  • YouTube comments
  • GitHub discussions
  • Support tickets mentioning video
  • Developer surveys

Common API Demo Mistakes

Marketing Over Substance

Problem: Too much sell, not enough show

Solution: Lead with code, save positioning for elsewhere

Outdated Examples

Problem: API has changed, video shows old version

Solution: Regular audits, version tracking, update process

Poor Audio Quality

Problem: Can't hear explanation while looking at code

Solution: External microphone, quiet environment, post-processing

Unrealistic Examples

Problem: Examples too simple to be useful

Solution: Show real-world complexity, acknowledge edge cases

Assuming Too Much Knowledge

Problem: Skipping over setup or prerequisites

Solution: State assumptions, link to prerequisite content

Example API Demo Script Outline

[0:00] "In this video, I'll show you how to authenticate
with the [API] and make your first request."

[0:15] "By the end, you'll have working code that
[specific outcome]."

[0:30] "Prerequisites: [list]. Links in the description."

[0:45] [Show terminal] "First, let's install the SDK..."

[1:30] "Now let's authenticate. You'll need your API key
from the dashboard..."

[2:30] "Here's our first request. [Explain code]"

[3:00] [Execute] "And here's the response. Notice that..."

[4:00] "Let's try something more complex..."

[5:00] "That's [what we built]. Check out [next resource]
for more advanced patterns."

Conclusion

API demo videos accelerate developer adoption by showing rather than telling. By focusing on code, maintaining technical accuracy, and respecting developers' time, you create content that drives evaluation and implementation.

Your API video checklist:

  1. Define target developer segment
  2. Choose appropriate video format
  3. Set up clean recording environment
  4. Script with code-first approach
  5. Record with clear narration
  6. Embed in documentation
  7. Track engagement and update

Developers learn by doing. Show them how to do it.
