External API integration
We connect your website, online store or application with external services — so data flows automatically between systems, without manual work.
What we integrate
Online payments
Stripe, PayPal, local processors — payment processing directly from your site or store.
CRM and ERP
Client, order and inventory sync with management systems. See our CRM PHP extensions project.
Shipping
Courier services — automatic shipping cost calculation and AWB generation.
Invoicing
Automatic invoice generation when orders are placed.
Email marketing
Mailchimp, Brevo — subscriber sync, automated triggers.
Custom API
Any service with API documentation — we build custom connectors.
How we work
- We analyze the external service API (documentation, authentication, limitations)
- We design the data flow between systems
- We implement the integration and test real scenarios
- We monitor and fix any post-launch issues
Pricing
Cost depends on API complexity and number of connected systems. We provide an estimate after requirements analysis — same as our custom software development.
