Build with the
SparkVox API
Turn podcasts and transcripts into LinkedIn posts programmatically. Submit content, receive webhooks when posts are ready, and manage drafts via REST.
Quick start
Everything you need to integrate SparkVox into your workflow.
Get an API Key
Create a key in Settings → Developer. Keys start with sk_sparkvox_.
Read the docs
Authentication, endpoints, webhooks, and code examples.
Create a project
Resolve YouTube duration with GET /api/url-metadata, then POST a URL or transcript. Processing is async.
Set up webhooks
Get notified when projects are ready or fail. Verify HMAC signatures.
What you can do
The v1 API covers the core repurpose workflow - long-form LinkedIn posts only.
- Submit podcast URLs or transcripts and receive LinkedIn posts asynchronously
- Resolve YouTube metadata (duration, title) via a public helper before creating projects
- List integrations, projects, and posts; delete projects when done
- Approve, edit, schedule (Buffer, Publer, LinkedIn), generate AI images, or upload custom images via REST
- Register webhooks for project.ready and project.failed events
- Same billing and pipeline as the SparkVox web app
