Authentication and secrets
Keys and tokens must be protected, rotated and limited to the permissions actually required.
WebForLess since 2003
Reliable connections between the systems your business depends on
An API integration is not simply a request that returns data. A dependable integration must handle authentication, validation, limits, failures, retries, logging and changes made by the external provider.
What must be designed
The invisible details determine whether an integration survives real use.
Data contracts
Incoming and outgoing fields need validation, mapping and clear ownership.
Failure behaviour
Timeouts, partial success, duplicate requests and provider outages require predictable handling.
Rate limits and cost
Request volume, caching and provider pricing should be understood before the integration scales.
Observability
Logs and alerts should make it possible to identify when the external service or internal mapping fails.
Examples of useful integrations
Common projects connect mapping and distance calculations, payment processing, transactional email, customer relationship systems, accounting tools, calendars, analytics and specialized industry platforms.
Before integrating, confirm whether the provider offers stable documentation, a test environment, appropriate support and terms that allow the intended use.
How we work
How WebForLess designs integrations that fail safely
An integration is reliable only when authentication, data mapping, retries, monitoring and ownership are designed alongside the successful request path.
- 01
Define the business event
Clarify what starts the exchange, what data moves and what outcome the user expects.
- 02
Review the source contract
Confirm authentication, rate limits, versioning, webhooks, error formats and service-level constraints.
- 03
Map and validate data
Translate fields deliberately, reject invalid values and preserve traceability.
- 04
Design failure behaviour
Plan timeouts, retries, duplicate prevention, queues and user-visible status.
- 05
Protect credentials
Store secrets outside public code, minimize permissions and rotate credentials when required.
- 06
Monitor production traffic
Record actionable errors, alert the right owner and document recovery procedures.

Practical questions before starting
What if an API is unavailable?
The integration should time out predictably, preserve required work, prevent duplicates and provide an actionable status instead of silently losing data.
Can older systems be integrated?
Sometimes. Available APIs, exports, database access, vendor support and security constraints determine whether a direct integration or controlled import process is safer.
Who maintains an integration after launch?
Ownership should be explicit because vendors change authentication, fields, limits and API versions over time.
