Your tools, talking to each other.
Direct integrations with the APIs your business already depends on — payments, messaging, e-commerce, accounting — built to handle authentication, webhooks, and failures properly, instead of a no-code chain that breaks silently.
An integration built around five things
Authentication & OAuth handling
API keys, OAuth flows, and token refresh handled securely, including reauthorization when a provider revokes or rotates credentials.
Webhook listeners & real-time sync
Incoming webhooks verified, queued, and processed reliably, so events like payments or status updates reflect in your system the moment they happen.
Data mapping between systems
Fields, formats, and IDs translated correctly between your schema and the third party's, so nothing gets dropped or mismatched in transit.
Error handling, retries & rate limits
Failed calls retried with backoff, rate limits respected automatically, and permanent failures surfaced instead of silently dropped.
Monitoring, logging & alerting
Every call logged with enough detail to debug fast, and alerts fire before a broken sync turns into a customer-facing problem.
When a Zapier chain stops being enough
DIY / no-code integration
- Brittle multi-step chains that break silently
- Per-task pricing that scales against you as volume grows
- Limited to whatever triggers the platform prebuilt
- No real error handling when an API changes
Custom-built integration
- Direct API-to-API connections built to survive edge cases
- One-time build cost, no per-task fees at scale
- Handles exactly the data your systems need, nothing more
- Monitored, with alerts before customers notice a problem
Five stages, from mapping to monitored launch
Map the data flow
Which systems need to talk, what data moves between them, and in which direction, documented before any code is written.
Handle authentication
API keys or OAuth set up securely, with token refresh and reauthorization handled from day one.
Build the sync logic
Data mapping, webhook listeners, and transformation logic built and tested against real data from both systems.
Handle failures gracefully
Retries, rate-limit handling, and alerting added so a temporary outage doesn't become a permanent data gap.
Monitor & launch
Live traffic watched closely at launch, with logging and alerts in place before handoff.
Common questions
How much does third-party API integration cost?
A single integration — one API, one direction of data flow, with basic error handling — typically starts in the low four figures. Multi-system integrations with two-way sync, webhook listeners, and retry logic run higher. The main cost drivers are how many systems need to talk to each other and how much the data needs to be transformed in between.
What APIs have you worked with?
Payment processors like Stripe, communication APIs like Twilio, e-commerce platforms like Shopify, accounting tools like QuickBooks, mapping services like Google Maps, and CRMs like Close and HubSpot, among others. Most well-documented REST or GraphQL APIs can be integrated regardless of prior experience with that specific provider.
What happens when a third-party API changes or goes down?
A properly built integration includes retry logic, timeouts, and alerting, so a temporary outage queues and retries instead of silently losing data. API version changes are handled through monitoring and an optional maintenance plan, so breaking changes get caught and fixed before they affect your business.
Can you integrate with an API that has no documentation?
Yes, though it takes longer. Undocumented or poorly documented APIs need to be reverse-engineered through testing, which adds discovery time to the project before implementation can start. This is more common with smaller or internal vendor APIs than with major platforms.
How long does an integration project take?
A single, well-documented API integration typically takes two to four weeks. Multi-system integrations with two-way sync and custom data mapping usually run six to ten weeks, since each connected system needs its own testing pass against real data.
