API research
Understand authentication, limits, endpoints and data contracts.
API · WEBHOOKS · SYSTEM INTEGRATION
API integration development between the systems you already use.
Custom API integration development for CRM, Telegram, web apps, payments, databases and third-party services using APIs and webhooks.
01 / Deliverables
What the work can include.
The exact scope follows the product workflow. These are the components that commonly matter for this type of project.
Webhook handling
Receive and verify events from external systems.
Data mapping
Transform fields and structures between incompatible products.
Authentication
Tokens, signatures and credential handling.
Reliability
Retries, deduplication, logging and error paths.
Custom adapters
Small backend services when a direct integration is not enough.
02 / Fit
Choose the format by the problem.
I do not force every project into one stack. The format should reduce complexity for the user and for the system.
Direct API
Both systems expose the required endpoints and events.
n8n orchestration
Several systems need a maintainable workflow around the APIs.
Custom backend
State, security or business logic is too complex for a visual workflow alone.
03 / Process
From unclear request to a working release.
1. Understand
Current process, users, inputs, outputs and constraints.
2. Reduce
Define the smallest architecture that solves the actual problem.
3. Build
Implement the end-to-end workflow, integrations and edge states.
4. Launch
Deploy, test real usage and iterate from observed issues.
FAQ
Questions before the first build.
Can you integrate a service without a ready-made plugin?
Yes, if it provides a usable API or webhook interface.
What if the API documentation is incomplete?
The integration can often be researched through available documentation, test environments and observed responses, but limitations need to be identified early.
How do you avoid duplicate events?
With idempotency rules, stable identifiers and controlled retry logic.
Can an integration be added to an existing project?
Yes. Existing systems can usually be extended without rebuilding the whole product.
YOUR PROJECT IS NEXT
Let’s build
something great.
A few sentences about your project are enough to start. A link, design or existing code helps estimate the scope.
