Build a developer-facing API — extensibility that makes your platform more valuable.
Developer-facing APIs turn your platform into a platform. Third-party developers build integrations. Partners extend functionality. Your product becomes part of their workflow instead of an isolated tool.
SaaS platform founder who wants to offer API access to allow customers, partners, and third-party developers to integrate with and extend the platform
A SaaS platform without an API is a closed system. Customers can only work within the interface you've built. An API makes the platform open: customers can automate workflows, sync data to other tools, and build custom integrations.
The platform flywheel: API access → third-party integrations → customers who've integrated are harder to churn → increased switching cost → increased LTV.
Stripe, Twilio, and Shopify all built developer-facing APIs as a core part of their growth strategy. The API is the product, even for non-API-primary products.
What a developer-facing API requires:
From your existing platform: The core data and actions need to be exposed as API endpoints. This means the platform's logic is decoupled enough that it can be called from an API layer.
New infrastructure: API key management. Rate limiting. Webhook delivery. Developer documentation portal.

One honest number to start.
Fixed-scope, fixed-price. The number below is the starting point — final scope is built from your brief.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
Developer-facing APIs have defined endpoints and infrastructure patterns. Fixed-price from the spec.
Questions, answered.
The most common developer use case first. Typically: list and retrieve core resources, create/update the most actionable resources, and webhooks for the most important events. Not everything on day one.
Webhook delivery with exponential backoff retry (5 attempts over 24 hours). Delivery log per webhook endpoint. Manual retry from the developer portal for failed deliveries.
