What do API development services include?

API development services involve designing, building, documenting, and maintaining application programming interfaces that allow different systems and applications to communicate. This includes REST and GraphQL API development, third-party API integrations, API gateway setup, authentication and authorization, rate limiting, versioning, and mobile backend development.

How much do API development services cost?

Costs depend on the number of endpoints, authentication complexity, and integration requirements. WebMob Technologies offers dedicated API and backend developers starting at $25/hr or $3,400/month. Full backend and API engineering teams with senior architects are available at $16,000/month for large-scale systems.

How long does API development take?

A focused API for a mobile app or web platform with standard CRUD operations and authentication can be built in 4 to 8 weeks. Complex API ecosystems with multiple third-party integrations, real-time webhooks, advanced security, and high-availability infrastructure typically take 3 to 6 months to design, build, and test.

Why choose WebMob Technologies for API and mobile backend development?

WebMob Technologies has 15+ years of backend and API development experience with 120+ in-house engineers skilled across Node.JS, Python, Java, and PHP. We have built APIs for 700+ projects globally and offer NDA protection, 100% code security, a 5-day risk-free trial, and team onboarding within 48 hours.

API Development Services

Q: What is the difference between REST and GraphQL APIs?

REST APIs use fixed endpoints and return predefined data structures — simple and widely supported. GraphQL allows clients to request exactly the data they need in a single query — reducing over-fetching and under-fetching. REST suits most standard applications, while GraphQL excels in complex, data-heavy frontends with variable data requirements.

WebMob Technologies delivers api development services trusted by businesses across the US and globally. From custom REST and GraphQL APIs to cloud-native backend infrastructure, our in-house team ships production-ready backends that scale from MVP to enterprise volume without cutting corners.
