What this service is for
What can an API integration specialist help you build?
Connect accounting, sales, forms and internal tools so data flows where it's needed. Integration specialists build no-code automations, webhooks and custom API connectors to cut admin, reduce errors and save time.
Sync sales and accounting
Automatically push orders, invoices and payments into Xero or your accounting system to reduce reconciliation work.
Capture and qualify leads
Connect webforms or marketing tools to your CRM and trigger follow-ups so leads are captured without manual copying.
Replace repetitive admin

Ideas for your brief
Project ideas you can brief
Three practical scopes you can use to brief freelancers. Deliverables are examples to agree with the freelancer — ongoing support is optional and negotiated separately.
No-code lead capture and CRM sync
Use Zapier or Make to capture leads from forms and route them into your CRM with basic lead scoring and notifications.
- Map form fields to CRM contact and lead objects
- Create Zapier/Make workflows to push new leads and update records
- Add conditional steps for lead scoring or tagging
- Test flows and provide a short handover guide
Xero bookkeeping connection and payments
Integrate your sales platform with Xero so sales, invoices and payment status are synchronised and easier to reconcile.
- Design data mapping between sales platform and Xero accounts
- Build connection (Xero API or through middleware) to create invoices and record payments
- Handle tax codes and customer matching rules for NZ settings
- Provide test run & deployment checklist
Custom middleware and webhook layer
For multiple systems or where no ready-made connector exists, build a small middleware service (serverless or hosted) to transform and route data reliably.
- Design an integration flow diagram and error-handling strategy
- Implement webhook receivers and API connectors (example: REST/JSON endpoints, OAuth where required)
- Build lightweight transformation logic and retry handling
- Deploy to a cloud environment and produce operational notes

Oliver Le LievrePricing guidance
How much does API integration cost?
Indicative NZD price bands to help you budget. Final cost depends on scope, APIs involved, security and ongoing platform fees.
Small automation (no-code)
Single workflow using Zapier/Make/n8n to sync forms, CRM or email lists. Includes mapping, testing and handover.
NZ$800–3,500
Medium integration (custom + middleware)
One or two system integrations with custom mapping, authentication (OAuth/API keys), logging and basic error handling.
NZ$4,000–15,000
Large integration or platform work
Multi-system integrations, bespoke middleware, data migrations, and enterprise-grade error handling or data reconciliation.
NZ$15,000–60,000+
What affects the price
- Number of systems to connect and whether they have public APIs
- Complexity of data mapping, reconciliation and business rules
- Use of no-code tools (Zapier/Make) versus custom code or middleware
- Security, hosting and ongoing maintenance requirements
Estimates are indicative and may exclude GST and ongoing software or platform fees. Final scope and freelancer rates are agreed directly with the freelancer — request a tailored quote on your brief.
Frequently asked questions
Common questions before you hire.
Answers to the questions clients commonly ask before starting a brief.
Still deciding what you need?
Start with the outcome and the context you already have. A polished specification is not required.
How long will an integration take?
Small no-code automations can be completed in days; medium or custom integrations commonly take weeks. Timeline depends on API complexity, testing needs and how quickly you can provide access and decisions.
Do I need a developer or will no-code tools work?
No-code tools (Zapier, Make, n8n) are often faster and cheaper for straightforward workflows. For custom auth, heavy transformations, or high-volume syncs, a developer-built connector or middleware is preferable.
Can you connect to Xero and other NZ accounting systems?
Yes — Xero provides an API and many freelancers have experience connecting sales platforms and payment systems to Xero; discuss required data fields and tax settings when briefing the project.
How do I know I can trust a freelancer?
Ask applicants for relevant examples, technical approach, and references. Unicorn Factory’s process is: create a project brief, relevant freelancers apply, you review applications, and Unicorn Factory makes warm introductions.
Will the integration need ongoing support?
Many integrations need occasional maintenance (API updates, credential rotation). You can agree ongoing support or retainer terms directly with the freelancer when you hire them.
