API
The controlled interface through which systems exchange data
Endpoints, authentication, validation, responses and rules for access.
Connected systems and controlled data
APIs and integrations for systems that need to communicate
We develop APIs and integrations that connect applications, services and partners with clear rules for data, errors and monitoring.
From990 €+ VAT
Indicative price for a small and well-defined integration. Multiple systems, two-way synchronization, high volumes, and complex processing are priced separately.
- REST API
- Webhooks
- Data synchronization
- Retry and idempotency
- Logging and monitoring
Connected systems
Data should not be manually copied between applications
When customer, order, billing, payment and document systems don't communicate, the team enters the same information multiple times.
We develop APIs and integrations that transfer data in a controlled manner and automate invoices, statuses, notifications, imports and synchronizations, within the limits of access provided by external platforms.
Clarification
API, integration and automation are different components of the same flow
Integration
The connection between two or more systems
Data mapping, transformations, synchronization, and handling cross-platform differences.
Automation
Action executed without repetitive manual intervention
Scheduled tasks, webhooks, notifications, documents and status updates.
Technical flow
From event to result, with validation and control
Source system
Comandă, client, plată sau document.
API and validation
Authentication, Mapping and Rules.
Processing
Webhook, queue, retry or task.
Destination system
Status, invoice, AWB or notification.
The exact flow depends on the capabilities and limitations of each system. Not every platform can be integrated.
Problems solved
Manual processes slow down the team and introduce errors
We map the data path, eliminate repetitive steps, and build mechanisms for situations where external services have little or no response.
Manual copying
The same information is entered into CRM, billing, store and reports.
Different statuses
The systems show conflicting values and no one knows the correct source.
Invisible errors
Failed processing has no logging, retry, alert, or reconciliation procedure.
Processes difficult to scale
Every new system requires manual interventions and improvised rules.
Suitable for
For companies that work in several systems and repeat the same operations
It is suitable when there is a clear flow, legal technical access and a measurable result.
When it's not appropriate
An integration cannot replace access, documentation or business rules
We cannot promise platform integration without API, permitted access, or vendor collaboration. We do not implement unauthorized access and do not expose scraping as an API.

Features and deliverables
What an integration project can include
Components are selected after documentation, flow and risk analysis.

- API keys, OAuth, JWT and scopes
- Validation, rate limiting and permissions
- Documentation and examples
Data and Sync
- Field mapping and transformations
- Import, export and reconciliation
- One- or two-way synchronization
- Conflict rules and the source of truth
Processing and Automation
- Webhooks, polling and scheduled tasks
- Celery, Redis and Asynchronous Processing
- Retry, backoff and idempotency
- Automated notifications and documents
Operation and quality

Architecture
New API, external API and synchronization mechanism
Control over endpoints and rules
We build it for the project's data, permissions, and consumers.
Integration across vendor boundaries
We depend on documentation, versions, limits, costs and availability.
Webhooks and events
Suitable when the supplier transmits the changes immediately.
Tasks and batch processing
Suitable for volumes, reports and systems without webhooks.
Mechanisms
Webhooks, polling, scheduled tasks and queues
Webhook
The external system broadcasts the event when it occurs.
Polling
The integration periodically checks for new or changed data.
Scheduled task
Processing runs at defined times or intervals.
Asynchronous process
The operation is queued for execution and controlled retry.
Commercial integrations
Payments, invoicing, couriers, CRM and ERP
The status is confirmed by the processor mechanism
The customer owns the merchant account, the contract and bears the commissions.
We automate the tax-validated technical steps
The setup and accounting rules are confirmed by the client and the accountant.
AWB, rates and tracking where the API allows
Commercial agreement and access belong to the customer.
Integration depends on documentation and vendor
ERP projects frequently require sandboxing and external technical collaboration.
Initial analysis
Complex integrations must be verified before a firm offer
- Documentation, endpoints and authentication
- Sandbox, payloads and limits
- Volumes, frequency and business rules
- Errors, Retry, Reconciliation and Security
The audit can be estimated separately and become the basis of project specifications.
Process
From manual process to monitored integration
- Initial discussionSystems, problem and outcome.
- FeasibilityDocumentation, Access and Limits.
- Flow mappingDates, moments and errors.
- SpecificationsDeliverables and acceptance.
- Test environmentSandbox and test data.
- DevelopmentAPIs, webhooks, and tasks.
- TestingErrors, timeouts and duplicates.
- ValidationReal scenarios with the client.
- ReleaseControlled activation.
- StabilizationCorrections and monitoring.
Reliability and security
Good integration also handles situations where things don't work
External services, network and data can cause errors. We do not promise absolute functionality; we build control and recovery mechanisms.
Temporary errors and backoff
We limit attempts, record status and alert when processing cannot be completed.
Preventing duplicates
Foreign Identifiers, Idempotent Keys, Transactions, and Database Constraints.
Minimal access and protected secrets
HTTPS, authentication, authorization, validation, key rotation and logs without sensitive data.
Indicative packages
Integration, automation or connected platform
The final offer is determined after analyzing the systems, documentation and flow.

Estimate and Responsibilities
What influences the price and what the customer must provide
- Systems, endpoints and authentication
- Volume, frequency and direction of data
- Errors, retry, security and monitoring
The customer provides documentation, accounts, sandbox access, test data, validated rules, and a committer.
Keys, tokens and passwords are not submitted via the form; they are later transmitted through a secure channel.
After launch
A critical integration must be monitored and updated
Providers may change APIs, authentication, limits or conditions. Monitoring, adaptations and new developments are separate stabilization services.
Technology
