We integrate CRM systems, payment gateways, analytics, advertising platforms and internal services — with proper architecture, logging, and resilience built in from day one.
Salesforce, HubSpot, Bitrix24, SAP — bidirectional sync with conflict resolution.
Stripe, PayPal, LiqPay, Fondy, WayForPay — with idempotency and full audit trail.
Google Analytics, Meta Ads, TikTok Ads, Mixpanel — event tracking and conversion pipelines.
SendGrid, Twilio, Telegram Bot API, Slack — reliable delivery with fallbacks.
REST and gRPC inter-service communication with proper contracts and versioning.
Proper layering, abstraction over third-party clients, so switching providers doesn't break everything.
Exponential backoff, deduplication keys, dead-letter queues. No lost events, no double charges.
Every request/response logged with correlation IDs. Alerting on error rate spikes.
OpenAPI/Swagger specs, runbooks, and handover documentation for your team.
Clean separation between your core system and external dependencies.
An API integration connects your system with external services: CRM, payment gateways, delivery services, advertising platforms, messengers. A well-built integration runs silently for years. A poorly built one breaks at 3am and causes lost transactions.
Our integration experience includes: Bitrix24, Salesforce, HubSpot (CRM), LiqPay, Fondy, Monobank, PrivatBank, Stripe, PayPal (payments), Nova Poshta (delivery), Google Analytics, Meta Ads, TikTok Ads (analytics), Telegram Bot API, SendGrid, Twilio (notifications).
Every integration we build has three reliability guarantees: idempotency (a repeated request will not cause double-charging), retry mechanism with exponential backoff (a temporary third-party API failure will not cause data loss), structured logging (every request and response is stored for debugging and audit).
Cost depends on complexity: simple one-way integration — from $500 (1–2 weeks), bidirectional sync with queues — from $2,000 (3–4 weeks), multi-provider system with failover — from $4,000 (4–8 weeks). Free consultation and scoping included.
One service, one-way sync. 1–2 weeks.
Queues, retries, logging, idempotency. 3–6 weeks.
Failover, circuit breaker, full audit trail. 4–8 weeks.
A simple integration (one service, one-way sync) starts at $500. A complex bidirectional integration with queues and retries from $2,000. A multi-provider system with failover from $4,000.
Yes. We have experience integrating Salesforce, HubSpot, Bitrix24, SAP, and payment systems including Stripe, PayPal, LiqPay, Fondy and WayForPay.
An idempotent request produces the same result even if executed twice. This prevents double-charging when a payment request is retried. We build all payment integrations with idempotency by default.
A simple integration takes 1–2 weeks. A complex one with full testing takes 3–6 weeks. Depends on the quality of the third-party API documentation and the number of edge cases.
We build integrations with resilience mechanisms: exponential backoff for retries, dead-letter queues for failed events, circuit breakers to isolate failures, and alerts when error rates spike.
