API & Integration Solutions We Build

WDL builds integration solutions that help systems exchange data securely, remove duplicated work and improve operational visibility.

REST API Development

Secure API endpoints for creating, reading, updating and exchanging data between systems and applications.

System Integration

Connections between portals, CRMs, LMS platforms, databases, payment systems and internal business platforms.

Data Synchronisation

Scheduled or real-time data movement between systems to reduce manual entry and improve data consistency.

Payment Integration

Integration with payment gateways for transactions, payment status, account updates and billing workflows.

Webhook Workflows

Event-based automation using webhooks for status updates, notifications, records and external platform events.

Secure API Access

Authentication, API keys, token validation, permission checks and controlled endpoint access.

Integration Logs

Logging and audit history for requests, responses, failures, retries and business-critical data movement.

App & Portal APIs

Backend APIs for mobile apps, customer portals, staff portals, SaaS products and reporting dashboards.

Technical Capability for Reliable API Integration

API integration needs secure access, clean data mapping, controlled error handling, stable endpoints and practical monitoring.

Authentication Handling

API keys, bearer tokens, signed requests, secure headers and access validation for protected integrations.

Data Mapping

Field mapping, format conversion, validation rules and structured movement of records between systems.

Error Handling

Controlled handling of failed requests, missing data, invalid responses, retries and exception logging.

Scheduled Sync

Scheduled integration jobs for regular updates, imports, exports, status checks and background processing.

Monitoring Visibility

Logs, status views and technical reporting to understand whether integrations are running correctly.

Integration Maintenance

Support when third-party APIs change, endpoints are updated or business workflow requirements evolve.

Technology Used for API Development & Integration

We use secure and maintainable technologies for API endpoints, integration workflows, data exchange and third-party platform connectivity.

REST APIs

Structured API endpoints for secure data exchange and platform connectivity.

PHP

Backend API development, integration logic and server-side workflows.

Laravel

API-first application structure, routing, validation and integration services.

MySQL

Data storage, mapping, synchronisation records and reporting queries.

AWS

Cloud-hosted APIs, secure infrastructure and scalable integration environments.

Security

Authentication, API keys, access control and protected endpoint handling.

Webhooks

Event-based integrations for real-time updates and automated workflows.

JSON/XML

Structured data formats for exchanging information between platforms.

Typical API Integration Use Cases

API development is useful when your business systems hold related data but do not currently share it in a controlled and reliable way.

Synchronise Records

Move records between systems so users do not need to enter the same information multiple times.

Connect Payments

Link payment gateways with portals, platforms, invoices, subscriptions or internal payment status records.

Connect LMS Platforms

Integrate learning platforms, Moodle environments, student systems and reporting databases.

Connect CRM Data

Exchange customer, lead, applicant, agent or contact data between CRM tools and business platforms.

Web Developers London develops secure REST APIs, integration endpoints, data synchronisation workflows, webhook handlers and third-party software connections for portals, SaaS platforms, CRMs, LMS platforms, payment systems, databases and reporting tools.

Yes. WDL can connect existing systems using available APIs, database-level integration or controlled import and export workflows. The approach depends on what access each system provides and how the data needs to move between them.

Yes. WDL can build secure API endpoints for portals, mobile apps, SaaS products and dashboards so user-specific data can be accessed, updated and displayed through controlled application interfaces.

Yes. WDL can integrate payment gateways with portals, SaaS platforms, application systems, subscription workflows and internal records so payment status and transaction-related data can be handled automatically.

Yes. Integration workflows can include request logs, response logs, failure messages, retry handling and audit history so technical issues and data transfer problems can be reviewed.

Yes. WDL can integrate Moodle and LMS platforms with student systems, reporting tools, portals, authentication workflows and other business systems where suitable API or database access is available.

API integrations can include secure authentication, API keys, tokens, signed requests, HTTPS, access control, validation and logging. The security model depends on the systems being connected and the sensitivity of the data.

Yes. WDL provides support for existing integrations, third-party API changes, endpoint updates, failures, performance issues and new integration requirements after launch.
