Automate reporting and workflows
Pull data from multiple sources into dashboards and trigger workflows that remove manual handoffs.
Open your platform to partners

Questions about hiring an API developer
Straight answers to what NZ business owners ask us most.
How long will my API project take?
Small integrations can take a few days to a couple of weeks; medium projects commonly take several weeks; larger platform work may take months. The freelancer you hire will give a timeline based on your brief.
How do I choose the right freelancer?
Look for relevant examples of similar integrations, clear documentation samples, and hands-on experience with your primary platforms (for example Xero, Shopify or your CRM). Ask for a short proposal and references in applications.
Who owns the code and IP?
Ownership is agreed between you and the freelancer in the contract. If you need full ownership, state this in your brief and confirm it before work starts.
What about security and compliance?
Specify security needs in your brief (data encryption, user authentication, data retention). For regulated data (payments, banking, health) confirm compliance requirements before development—freelancers can implement controls but you must agree exact obligations in the contract.
Do these prices include ongoing hosting or API fees?
No. Estimates typically exclude ongoing hosting, API call charges or third-party service fees; include expected operational costs in your brief so applicants can factor them into proposals.
What should I include in an API project brief?
List the systems to connect (for example Xero, Shopify or a CRM), what data should move and how often, who will use the result, and any security needs. If you are unsure, describe the manual job you want to stop doing and applicants can propose the approach.
