API & integrations

Connect yourtools properly

Custom APIs and integrations for payments, CRMs, WhatsApp, email, SMS, maps and third-party tools, so your team stops copying data by hand.

Integration scope

One system,not five spreadsheets

We build the APIs and integrations that let your existing tools talk to each other, so data moves automatically instead of through manual copy-paste.

01

Custom REST APIs

Secure, documented APIs built around your data and business logic.

02

Payment Integrations

Stripe, PayPal and regional payment gateway integrations with proper error handling.

03

CRM & Messaging

CRM, email, SMS and WhatsApp integrations that turn conversations into records.

04

Webhooks & Automation

Event-driven workflows that trigger notifications, updates and approvals automatically.

05

Third-Party APIs

Maps, calendars, analytics and other external APIs connected into your product.

How it works

Clear scope,private by default

We can sign an NDA before detailed discovery. After that, we confirm scope, price, milestones, delivery dates and ownership in writing before development starts.

NDA available for confidential ideas, business processes, customer data and internal systems.
Your quote explains what is included, what is not included and what can be added later.
Work is delivered in milestones so you can review progress before the final handover.
