Brief
You describe the users, the job to be done, current tools and any hard date or constraint. A page is enough.
Services
APIs and integrations that other software can depend on
Most modern products are a conversation between systems. Hirvex Technologies designs and builds APIs, webhooks and integrations so your app, your partners and your internal tools share one contract. Documentation, auth and versioning are part of the work, not a README written after the first outage.
Who this is for. Product and engineering leads who need a stable interface between a mobile app, a web app, a partner, or a legacy core.
Problems we typically meet
These are the patterns that show up before a useful first release—not abstract “digital transformation” language.
- Every new channel re-implements business rules.
- Partner integrations break when a field is renamed.
- There is no idempotency, so payments or tickets duplicate.
- Internal teams call the production database because no API exists.
How we approach the work
We define resources, errors and auth before writing controllers. Versioning and deprecation are explicit. Integrations with third parties include mapping, retries and an operations view of failed jobs. If the third-party API is poor, we isolate it so your product does not inherit that shape forever.
What a serious first release can include
Scope is confirmed in discovery. This is the shape of work we are equipped to deliver—not a menu you must buy in full.
- REST API design and implementation
- Token, session and key-based authentication patterns
- Webhooks, queues and retry policies
- Third-party billing, maps, messaging and ERP connectors
- API documentation your partners can use
- Contract tests around critical paths
- Gateway and rate-limit basics for public APIs
What we need from you
A useful brief is better than a long one. If you can answer most of the following, we can propose a first slice instead of a theatre estimate.
- Who will use this, and what must they finish in a session?
- Which systems must stay (accounting, payments, identity, a shop)?
- What is already live that we should not break?
- Any hosting region, language or compliance rule that is non-negotiable?
- The date that actually matters—and why.
How an engagement runs
Four steps. No mystery bench.
Scope
We reply with clarifying questions and a first-release outline: modules, roles, integrations and what “done” means.
Build
Named engineers work in visible increments, with staging you can click and a weekly written status.
Run
Launch, handover and a support path. The system is yours to operate—not a black box we disappear from.
Questions we are asked
REST or GraphQL?
REST is our default for business APIs because it is easy for partners to consume. GraphQL is used when the client graph genuinely needs it. We do not add GraphQL as decoration.
Can you integrate a system with no API?
Sometimes via supported file drops, database views you own, or a vendor’s official connector. We do not scrape UIs as a production integration strategy.
Will you document the API?
Yes. If partners consume it, documentation is a deliverable. Internal-only APIs still get a concise contract.
