API & integration specialist for digital agencies
Your client needs an integration. You need someone who can build it.
Crazy Logical is a specialist API and integration partner for digital agencies.
We handle the API work your developers don't usually do: third-party APIs, custom endpoints, webhooks, OAuth, data syncs and middleware. We can plan it for your team, or build the integration layer while they build the site.

The integration work outside your team's comfort zone
Your developers can build the WordPress or Shopify site. Then the client asks:
“Can you connect the site to our booking system?”
Or pull data from a partner's API. Or work with a platform whose documentation is three years out of date. Or fix a flaky integration someone else built.
Suddenly a straightforward project becomes an integration project.
That's where Crazy Logical comes in.
Start with a plan. Then decide who builds the integration.
Your developers always own the site. We fill the integration gap, as much or as little as you need.
What we integrate
If it has an API, we've probably worked with one like it. If we haven't, the feasibility assessment is how we find out.
Third-party API integrations
Connect your client's site or app to the platforms they rely on: CRMs, payment providers, marketing tools, booking systems and industry-specific APIs.
Custom APIs & webhooks
Build the endpoints, webhooks and callbacks another system needs to talk to your project.
Data sync & middleware
When two systems don't fit together cleanly, we build the layer between them: mapping, transformation, queues and retries.
Legacy & awkward APIs
SOAP services, poorly documented vendor APIs, strict rate limits and unusual authentication.
Example integration problems
Illustrative examples of the work we take on, not client projects.
WebsitetoCRM
Send enquiries and customer data into a CRM, with retries for when the CRM's API is down.
Payment webhookstoCustom app
Handle payment events and keep order or subscription status in sync with a custom application.
Legacy SOAPtoModern REST
Wrap an old SOAP service in a clean REST API that a new front end can use.
Partner APItoWebsite
Pull data from a partner's API on a schedule and publish it on the client's site, within the API's rate limits.
Call Crazy Logical when…
- The integration doesn't exist.
- The vendor API is poorly documented.
- The API has rate limits, pagination or authentication quirks.
- Multiple systems are involved.
- Your existing integration keeps failing.
- Your team doesn't want to own the integration long-term.
- You're not sure the API can actually do what the client wants.
- Your developers could build it, but want a plan from someone who has done it before.
- You don't want to risk under-quoting the project.
If the integration looks complicated, it's probably worth talking to us.
Before you quote the client, find out what you're actually selling.
Send us the systems you need to connect. We investigate the available APIs, authentication, data access and likely architecture, then tell you what is feasible and how to approach it. Your developers can build from the plan, or we can build the integration layer for them to connect to.
More complex integrations can be built as a fixed-price Integration Sprint (from $4,500 AUD + GST), scoped after an assessment.

A simple way to get difficult integrations done
No open-ended “let's see how many hours it takes”. You know the scope before anyone builds.
Tell us what needs connecting
Send us the systems and what the client needs to happen.
We investigate
We look at APIs, authentication, data access and constraints.
You get a plan and a fixed scope
A clear recommendation your developers can build from, and a fixed price if we're building the integration layer.
Choose who builds it
Your developers build from the plan, or we build the integration layer while they build the site.
Fixed prices, agreed up front
Every engagement starts with a defined scope and a fixed price. No hourly billing.

Questions agencies ask
Can you work with our existing developers?
Yes. We can write the plan your developers build from, or build the integration layer while they build the site. The site itself always stays with your team.
Do we have to hire you to build it after the assessment?
No. The assessment is yours to keep. Your developers can build from it, or we can quote a fixed-price build of the integration layer.
Do you work directly with our client?
Usually we work behind the scenes as your white-label integration partner. We can adapt to whatever communication model works best for your agency.
Do you charge hourly?
No. Our core services are productised and fixed-price. Where a project genuinely falls outside a defined scope, we agree the next piece of work before proceeding.
Do you maintain integrations after launch?
Yes. Maintenance and ongoing support can be handled through defined service arrangements.
Can you work with legacy systems?
Yes. Legacy APIs, SOAP, OData, custom endpoints and awkward vendor systems are exactly the sort of work we specialise in.
Will you compete with our agency?
No. We don't build websites. We're a specialist integration partner, and the site always stays with your team.
Where are you based?
Gold Coast, Queensland, Australia. We work with agencies Australia-wide.
Got an integration outside your team's comfort zone?
Tell us what you're trying to connect. We'll plan it for your developers or build the integration layer alongside them.
