Third-Party & API Integrations
Stop wasting time doing manual data entry. We connect your website, web applications, and backend tools using APIs and custom webhooks, so data moves automatically between systems instead of being re-entered by hand.
Who it helps
Scaling businesses and enterprises suffering from 'software bloat'—using dozens of disconnected SaaS tools that require manual data transfer.
What it solves
Focused implementation for the specific business problems listed below.
Overview
For service businesses and teams needing reliable automated workflows, lead capture, and third-party data synchronization.
Scope
Technical scoping, architecture, and development of custom API connections (REST/GraphQL) or middleware (Make/Zapier) between your web properties and external services.
Outcomes
- Elimination of manual, error-prone data entry across departments.
- A single source of truth for customer and operational data.
- Drastically improved team efficiency through automated workflows.
- Scalable infrastructure that easily accommodates new software tools.
Cost & Timeline
How much does it cost?
Pricing depends heavily on the specific API involved, its documentation quality, and whether authentication (OAuth) or webhook handling adds complexity. We assess technical feasibility first and provide a fixed quote once the scope is clear.
How long does it take?
Straightforward integrations typically take 1–3 weeks; integrations with limited documentation or complex data mapping can take longer.

The problems we solve
Common reasons businesses choose this service.
The Problems
Sales reps spend 2 hours a day manually copying leads from the website into Salesforce.
Inventory on the eCommerce site isn't syncing with the warehouse ERP, leading to overselling.
A critical business tool doesn't have a native integration with your website platform.
Data silos are preventing leadership from seeing the full customer journey.

Process
How we deliver this service.
1
API Auditing
We review the API documentation for both endpoints to determine technical limits, rate limits, and data formats.
2
Data Mapping
We map exactly how data fields from System A (e.g., 'First Name') translate to System B.
3
Middleware Development
If a direct connection isn't possible, we build secure middleware scripts to translate and route the data.
4
Security & Error Handling
We implement security protocols and build 'retry logic' so data isn't lost if an API goes down temporarily.
5
Load Testing
We run massive batches of test data through the integration to ensure it holds up under pressure.
Use Cases
Common applications.
Custom ERP to Shopify
Building a two-way sync that pushes real-time inventory from an obscure legacy ERP up to a headless Shopify storefront.
Automated Onboarding Flow
Connecting Stripe, Webflow, and HubSpot so that when a client pays an invoice, a project is automatically created in Asana.
Aggregated Dashboarding
Pulling data via API from 5 different marketing platforms into a single, custom React dashboard for executive reporting.

When it is not the right choice
- -We cannot integrate systems that completely lack an API or export mechanism.
- -Fixing bugs inside the third-party software itself (we only control the connection).
- -Providing legal compliance consulting for data transfer (e.g., cross-border GDPR).

FAQ
Frequently asked questions.
Direct answers to common questions about scope, technical delivery, and project expectations.
We factor that into scoping — a technical feasibility review happens before we commit to a fixed price or timeline.
Yes, though we recommend scoping and testing integrations individually to keep debugging manageable.
