API Product Manager
API Product Managers own the API as a product — defining strategy, writing API design guidelines, managing versioning and deprecation, and communicating with external developers who depend on their APIs. Their English work includes writing API product roadmaps, authoring deprecation notices, engaging with the developer community, and presenting API business metrics to executives. This path builds the vocabulary for discussing API product decisions and communicating them clearly to both technical and business audiences.

Vocabulary spotlight
4 terms every API Product Manager should know in English:
A product management philosophy that treats APIs as products with their own lifecycle, roadmap, target developers, and success metrics — not just internal technical artifacts
"Our API-as-a-product approach means every endpoint decision is evaluated against developer experience and integration success rate, not just technical correctness."
A modification to an API that is not backward compatible — requiring existing consumers to update their integration to avoid failures
"The field rename is a breaking change — we need a 90-day deprecation notice and a migration guide before removing the old name."
An official communication to API consumers that a feature, endpoint, or version will be removed at a specified future date — giving time for migration
"We sent the deprecation notice for v1 six months in advance, with migration examples and a personal outreach to our 20 highest-usage integrators."
The practice of generating revenue from API access — through usage tiers, per-call pricing, freemium models, or partner revenue sharing
"Our API monetisation model uses tiered pricing: free for 10,000 requests/month, then usage-based pricing above that."

Recommended exercises
Real-world scenarios you'll practise
- Writing a deprecation notice email to all active API consumers: clearly communicating the timeline, what is changing, migration steps, and support resources
- Presenting API product metrics to a VP: active developers, API call volume, integration success rate, and time-to-first-successful-call
- Facilitating an API design review: gathering feedback from developer relations, engineering, and legal before finalising a new endpoint design
- Explaining API versioning strategy to an engineering team: why the team will maintain v1 and v2 simultaneously for 12 months during migration
