API integrations between business systems
Most businesses already use several systems that do not talk to each other: a website, a CRM, accounting software, a payment provider, a delivery service, messengers. People fill the gaps by copying data by hand. An API integration connects these systems directly, so data moves once, automatically, and every system stays up to date.

In short
In short
- 01
An API is the documented way one system lets another read or change its data; a webhook is a notification one system sends when something happens.
- 02
Before building, we check what each system's API actually allows — some only read, some limit the number of requests, some are poorly documented.
- 03
Integrations fail sometimes; what matters is that failures are detected, retried and reported, not silently lost.
- 04
Simple connections can use no-code automation tools; complex or critical ones are better built as code you control.
- 05
Every integration is documented, so another developer can maintain it.

Scope
Typical integrations
- Website and CRM: leads, orders, customer data.
- Online store and accounting: products, prices, stock, orders, invoices.
- Payment provider and order system: payment status, refunds.
- Delivery services: rate calculation, shipment creation, tracking.
- Messengers: notifications to customers and staff, bots that read data from your systems.
- Marketing platforms: audiences, offline conversions, product feeds.
- Internal systems: HR, inventory, service desks.
How we build integrations
Check the APIs first
We read the documentation and test each API before estimating: what data is available, how authentication works, what the limits are, whether there is a test environment. Surprises found here are cheaper than surprises found halfway through the project. Background in API.
Design the data flow
Which system is the source of truth for each piece of data, what triggers a sync (an event, a schedule, a user action) and what happens on conflict. Events are delivered by webhooks where available, and by scheduled polling where not.
Handle failure
Networks drop, services go down, tokens expire. Each integration:
- retries temporary failures with increasing delays;
- queues data so nothing is lost while a system is unavailable;
- protects against processing the same event twice;
- logs every exchange and alerts a person when something needs attention.
Secure it
API keys and tokens are stored securely on the server, never in the browser or in code repositories. Incoming webhooks are verified so that forged requests cannot change your data. Access is limited to what each integration needs.
No-code tools or custom code?
Tools such as n8n, Make or Zapier connect popular services quickly and are a good fit for simple, non-critical flows. Custom code is better when the logic is complex, the volume is high, the data is sensitive or you need full control over hosting and behaviour. Often the right answer is a mix. The comparison is in n8n vs Make vs Zapier, and broader automation in workflow automation.
Local systems
Many Azerbaijani providers — banks, payment services, delivery companies, government portals — have APIs of varying maturity. Some are well documented; others require direct contact with their technical team. We factor this into the estimate and, where needed, work with the provider's support on your behalf.
What we need from you
- The list of systems and what should flow between them.
- Administrator access or API credentials for each system.
- Contacts at providers whose APIs require agreements or approval.

FAQ
Frequently asked questions
What if a system has no API?
Alternatives include scheduled file exports, direct database access, email parsing or, as a last resort, automating the user interface. Each is less reliable than an API, so we explain the trade-offs.
Who maintains the integration after launch?
Integrations need occasional updates when a provider changes its API. That can be part of a support agreement, or your own developers can maintain it using the documentation we hand over.
Can we see what the integration is doing?
Yes. We provide logs or a simple dashboard showing recent exchanges, errors and retries.
