Perth API developers for businesses tired of double entry, broken connectors and reporting delays. We build custom APIs and system integrations that keep data moving properly.
API development Perth businesses can rely on: REST APIs, middleware, webhooks and API integration Perth teams can run across accounting, CRM, e-commerce, job management and payroll platforms with fixed pricing and clear scope.
Perth SMBs pick HELLO PEOPLE for API development because we have already integrated with the platforms you use. Every project runs through the founder, from the scoping call to production monitoring.
Week 0
Fifteen minutes to map the systems, data flows and edge cases. In-person in Perth if that suits. Fixed-price quote inside 48 hours.
Weeks 1-N
Real data flowing between your actual systems, not mock environments. You see the integration working every two weeks.
Deploy
Production deployment with monitoring, alerting and error logging. If an API fails at 2am, automated retries handle it and we get notified. Thirty days of post-launch support included.
Five categories of API and integration work, one Perth team building all of them. Each category has been delivered for real Perth SMBs and is available as a fixed-price scope.
We build RESTful APIs in Laravel, Node.js, .NET and Python. Clean resource-based endpoints, proper HTTP methods, consistent error responses, pagination, filtering and sorting.
Your mobile apps, React frontends, partner systems and internal tools all consume the same API. One backend, many consumers.
Authentication with JWT, API keys or OAuth 2.0. Rate limiting, input validation, CORS. OpenAPI/Swagger documentation included.
Connecting your business systems so data flows automatically. CRM to accounting. E-commerce to inventory. Website to ERP. Job management to payroll.
Xero, MYOB, Salesforce, HubSpot, Shopify, WooCommerce, Square, Stripe, simPRO, ServiceM8, Australia Post: we have integrated with most platforms Perth businesses use.
Real-time sync via webhooks. Scheduled batch sync for systems without webhook support. Queue-based processing for high volumes. Error recovery and retry logic on every connection.
Real-time data flow between systems. When an invoice is created in Xero, your CRM updates. When a Shopify order comes in, your warehouse system queues it. When a form is submitted, your sales pipeline triggers.
We build webhook listeners that validate payloads, process data, handle retries and log everything. Reliable event-driven architecture, not fragile point-to-point scripts.
For systems that do not support webhooks natively, we build polling services with change detection.
When System A speaks a different language to System B, you need middleware. We build the translation layer: mapping fields, converting formats, applying business rules, enriching data.
Common scenario: your job management software needs data from your accounting system, but the data shapes are completely different. Our middleware handles the transformation so both systems stay clean.
Handles data validation, field mapping, format conversion (JSON, XML, CSV, EDI), and business logic in one manageable layer.
Stripe, Square, PayWay, B2Bpay, Tyro, Windcave: we build payment integrations that process transactions securely and reconcile with your accounting software.
Invoice payment links, subscription billing, split payments, refund automation. Connected to your MYOB or Xero so every transaction reconciles automatically.
PCI compliance, tokenisation, and secure credential management built into every payment integration.
No hourly billing that spirals, no vague estimates. Here is how fixed-price Perth API development actually works, from first call to signed scope.
Tell us which systems need to talk. We give you an honest answer on whether an off-the-shelf connector will do, whether custom middleware is worth the spend, and what the realistic timeline looks like. In-person in Perth if that suits.
After the free consultation and a proper discovery of the systems, data flows and edge cases, you get a fixed price for the entire Perth API integration project. No hourly billing that spirals.
Every API we build ships with monitoring, alerting, error logging and automated retries. If something breaks at 2am, we know before you do. Fixed-price monitoring plan optional after launch.
Why HELLO PEOPLE
Connecting systems is a big call. Here is how HELLO PEOPLE compares to the three other realistic paths for a Perth business.
| Concern | HELLO PEOPLE | Zapier / Make | Freelance developer | Vendor connector |
|---|---|---|---|---|
| Fit to your Perth workflow | Built to your exact data model | Fits simple cases, breaks on volume | Depends on the person | Vendor decides the fields |
| Complex business rules | Custom code, any logic you need | Simple if/then only, then it breaks | Depends on the person | Off-the-shelf, generic |
| Volume and reliability | Queue-based, retries, monitored | Fine for low volume, fails silently | Depends on the person | Depends on the vendor tier |
| When third-party APIs change | We fix, monitored contract | You wait for vendor update | You call the person | Vendor updates on their schedule |
| Ongoing cost | One-off + optional support plan | Per operation, per month, forever | Hourly + scope creep | Per user, per month, forever |
| Direct access to the builder | Email Kasun, get Kasun | Support ticket queue | Depends on the person | Support ticket queue |
| Code and integration ownership | You own the code and the docs | Vendor owns the workflow | Often disputed at handover | Vendor owns everything |
A Perth trades business was entering job data into simPRO, then re-entering invoices into MYOB, then manually updating their customer portal. We built API integrations that sync jobs, invoices and customer data automatically across all three platforms.
Read the full case studyWe had three people spending half their day copying data between systems. HELLO PEOPLE connected everything with APIs. Now invoices, job updates and customer records sync automatically. My team works on actual work instead of data entry.
Data flowing automatically, less manual entry, cleaner reporting, integrations you can trust. Here is what custom API development delivers for a Perth SMB, once it is built and running.
We are in Perth. Not offshore behind a local phone number. When you need to workshop how your systems connect, we can sit across the table and map it out on a whiteboard.
API projects need tight communication: data formats, business rules, edge cases. Being local means questions get answered in hours, not days.
Xero, MYOB, Salesforce, HubSpot, Shopify, simPRO, ServiceM8, SharePoint: we have built integrations for most of the platforms Perth businesses use. We know their APIs, their limits, and their quirks.
Your API integration connects your actual systems with proper error handling, retry logic and monitoring. Not a demo that breaks the first time an API rate limit hits.
When off-the-shelf connectors do not fit, we build custom REST APIs from scratch. Clean endpoint design, proper authentication, versioning, documentation.
Your mobile app, web portal, partner systems and internal tools all consume the same reliable API. One source of truth, multiple consumers.
API integrations fail silently when built poorly. Ours include monitoring, alerting, error logging and automatic retries. If something breaks, we know before you do.
Queue-based processing for high-volume data. Webhook listeners that handle bursts. Scheduled sync for systems without real-time support. Built to run reliably at scale.
Every API we build uses proper authentication (OAuth 2.0, API keys, JWT tokens) depending on the use case. Data encrypted in transit and at rest. Access controls and audit logging built in.
For Perth businesses handling sensitive financial or customer data, we deploy within your infrastructure and follow Australian data residency requirements.
Every API project is different, but the delivery structure stays the same. Discover, design, build, test, deploy. You always know what phase you are in and what has to happen next.
Custom REST API development, third-party system integration (Xero, MYOB, Salesforce, Shopify, etc.), webhook development, API middleware, payment gateway integration, and legacy system data migration. We build in Laravel, Node.js, .NET and Python.
We start with a free scoping call to map the systems involved, the direction of data flow and the exception cases, then provide a fixed-price quote before any work begins. A single SaaS-to-SaaS integration sits at the lower end. A custom REST API for a mobile app or web portal, or a multi-system integration hub, is larger. No hourly billing - you know the full cost upfront.
Yes. Accounting integrations are one of our most common projects. We connect Xero and MYOB to CRMs, job management tools, e-commerce platforms, custom software and websites. Two-way sync, automatic invoice creation, payment reconciliation.
We work with what you have. Direct database connections for legacy systems, file-based integration (CSV, XML) for older platforms, screen scraping as a last resort. If data exists in a system, we can usually get it out and into another system.
A straightforward two-system integration takes 2 to 4 weeks. A custom API with multiple consumers takes 6 to 12 weeks. Complex multi-system integrations with middleware can take 8 to 16 weeks. Fortnightly demos throughout.
Yes. We build backend REST APIs that mobile apps consume: user authentication, data sync, push notifications, file uploads, payment processing. The API serves both iOS and Android apps through one consistent interface.
Every integration we build includes monitoring, error logging and automated retries. If a third-party API changes or a connection fails, our retry logic handles transient errors. Persistent issues trigger alerts and we fix them before they affect your operations.
Yes. We regularly connect legacy Access databases, old desktop applications and on-premise systems to modern cloud platforms. Direct database connections, file export processing, or full data migration - whatever makes the most sense for your situation.
