Missing API access
Customer needed programmatic access for automation or integration and your product does not offer it. Common for technical buyers and platforms used in workflows.
Where this hits hardest
- Developer tools
- Data products
- Automation-heavy workflows
What this sounds like in cancellation feedback
- “Need to pipe data into our system, no API.”
- “Cannot automate the manual export step.”
- “Webhooks would solve our issue.”
- “Power user features blocked behind GUI-only access.”
How to reduce no api churn
- Ship a read-only public API in 90 days. Solves 60-70% of API requests at minimal complexity.
- Add webhooks for the top 5 events your customers care about. Often more useful than full REST API for automation.
- Document your API on your main marketing site, not buried in a developer subdomain. Buyer-decision artifact.
- Rate-limit by tier. API access free for read-only, paid tiers for write and high-volume.
- Track which endpoints get the most third-party traffic. The top 3 are your platform pillars; invest in their stability.
Frequently Asked Questions
▶Should every SaaS have an API?
Read-only API yes if your product owns customer data. Write API only when you have integration partners or developer customers. Building one for show wastes engineering time.
▶Should APIs be free or paid?
Read access often free with rate limits. Write access and high-volume gated to paid plans. Mirrors developer-platform pricing patterns from Stripe, Twilio, etc.
▶What is the difference between API and webhooks?
API is request-response; the customer pulls data when needed. Webhooks are event-driven; you push data to the customer when something happens. Most workflows need both eventually.
▶How do I know if I should build an API?
If 5+ paid customers in a quarter have requested one, or if your product is used in workflows that include other tools. Otherwise focus engineering on core product.
▶Should APIs use REST, GraphQL, or both?
REST for general use; covers 90% of integration needs. GraphQL only when customers explicitly need it (data-heavy, frontend-driven integrations). gRPC almost never for B2B SaaS.
