A modern web project is not just a storefront, but a complex communications hub. For a business to operate without delays and manual data transfer, the website must instantly sync with a 1C warehouse, send leads to amoCRM or Bitrix24, calculate shipping costs via CDEK, and accept payments via merchant acquiring (YooKassa, Stripe, SBP).
We develop and implement integrations of any complexity based on REST API, GraphQL, SOAP, and WebSockets. We don't just write code linking two systems. We design **fault-tolerant architecture**: configure logging of each request (payload), write retry queues for external service failures, and encrypt API keys according to the AES-256 standard.
With us, you are insured against “lost” payments, hanging orders, and leads that failed to reach the CRM, even if the integrated service temporarily disconnects or experiences glitches.
Integrated external services: from banking gateways to complex ERP systems
Lost transactions avoided thanks to implementing BullMQ / Redis request queues
Data exchange delay during asynchronous webhook processing
Automatic API gateway health monitoring with alerts in Telegram
If the amoCRM server freezes for 10 minutes, our website will not show an error to the buyer. It will record the order in a local Redis queue, and our system will retry sending data to the CRM automatically as soon as connection is restored.
We create reliable, documented, and secure data exchange channels.
External APIs regularly return 500, 502 errors or exceed rate limits. We package all transactions into internal queues.
On any error, the system retries sending with exponential backoff, guaranteeing delivery.
Storing tokens in plain text within code risks hacking and database leaks. We use secure environment configurations (`.env`) and encrypt private keys using the AES-256-GCM algorithm.
Your client data and access rights to payment gateways are protected to the maximum degree.
If we write a custom API for your mobile app or partner service, we strictly supply it with auto-documentation in Swagger format.
Third-party developers will be able to easily connect to your backend without lengthy consultations and source code reviews.
Sequential path from specification analysis to deploying fault-tolerant synchronization.
We analyze the API of integrated systems. We identify authorization requirements, request structure, and rate limits.
We map out field specifications. We define how data structures from one system (e.g., website cart) map into the formats of another (1C order).
We write a middleware layer (in Node.js or PHP) that accepts webhooks, transforms data, and executes requests to external endpoints.
We connect Redis/BullMQ to manage task queues. We set up logging of incoming and outgoing payload packages for fast incident analysis.
We simulate network errors: artificially disconnect external CRM, send invalid data, measure execution speed, and test the Retry mechanism's correctness.
We deploy the integration to the production server. We connect Telegram alerts that instantly notify the support team about external API failures.
We use a modern toolkit to create flexible and fast data exchange bridges.
Tools for debugging, documenting, and testing APIs. Allow simulating requests, validating JSON response schemas, and generating sandboxes (Mock servers) for tests.
In-memory data store and queue library. They provide ultra-fast asynchronous processing of heavy requests in the background, offloading the main website server.
Our core backend development environments. They allow deploying a lightweight, extensible REST API server or a WebSocket gateway with flexible request routing.
Cost depends on the number of connected services, communication protocols (SOAP, REST), and queue requirements.
