REST API Development and System Integration London

Softomate builds REST APIs, GraphQL APIs, webhook architectures and middleware integrations for London businesses across finance, property, healthcare and professional services. OpenAPI/Swagger documentation is produced for every endpoint, covering authentication, request schemas and error codes. OAuth 2.0 and JWT authentication protect all external-facing connections. Salesforce, SAP, HubSpot, Stripe, Microsoft Azure and AWS integrations are common delivery scopes. UK GDPR data minimisation, encryption in transit and audit logging are built into every project plan. Softomate clients commonly cut manual data re-entry from several hours per day to under ten minutes after REST API launch. Integration testing and Postman test collections are included in handover. A discovery workshop maps your current platforms, data flows and compliance requirements before scope and pricing are confirmed.

Yes. Softomate integrates bespoke applications with Salesforce, SAP and HubSpot through REST API, OAuth 2.0 and webhook patterns. Salesforce integrations can write leads, cases, custom objects and opportunity updates directly from external platforms. SAP integrations can connect finance, inventory and order management data with web applications and third-party tools. HubSpot integrations can sync contact records, deal stages, activity timelines and consent data in near real time. Microsoft Azure, AWS, Stripe and custom back-office platforms can join the same delivery scope. Softomate clients typically reduce cross-platform data lag from overnight batch updates to under sixty seconds after REST API integration launches. A technical discovery session confirms field mappings, authentication rules and error-handling requirements before build starts.

OAuth 2.0 is an authorisation framework that lets one system access another system's data on behalf of a user without sharing passwords. A client application requests a scoped access token from an authorisation server. The token defines which resources can be read or written. Softomate implements OAuth 2.0 authorisation code flows, client credentials flows and refresh token management for Salesforce, HubSpot, Microsoft Azure and custom APIs. JWT tokens add a second layer by encoding user identity and permission claims inside each request. Scoped tokens limit damage if credentials are compromised, because each token only covers the permitted endpoints. UK GDPR data access controls align with OAuth 2.0 permission scopes. A security review during discovery confirms which grant types suit your platform architecture and compliance requirements.

Yes. Softomate API projects include UK GDPR controls covering data minimisation, encryption in transit using TLS 1.2 or above, purpose-limited data access and audit logging. OAuth 2.0 scopes restrict which data each integration can read or write, supporting the principle of least privilege. Personal data fields are identified during discovery and mapped to lawful-basis records for each data flow. Retention controls and deletion propagation rules are designed into webhook and batch integration patterns. REST APIs serving personal data include consent-status checks before returning regulated fields. Subject access request and deletion workflows are scoped at delivery planning stage. Softomate recommends an ICO data-flow register update after each integration launch. A compliance review session confirms data categories, storage locations and risk controls before build approval.

Most custom REST API projects for UK businesses take four to ten weeks from discovery to production deployment. Discovery and technical scoping usually need one week to map data flows, confirm authentication requirements and agree endpoint contracts. OpenAPI specification drafting and environment setup take another three to five working days. Build work then covers endpoint development, OAuth 2.0 implementation, error handling and UK GDPR controls. Integration testing, UAT and Postman test collection handover normally add five to eight working days. Salesforce, SAP or HubSpot integrations with complex data transformations can extend timelines slightly. Softomate clients typically see automated data flows operational within thirty days of discovery. A scoped workshop gives a more precise schedule once platform architecture and compliance needs are confirmed.

API / system integration starter starts from £3,000 for implementation. One bounded system connection with accessible APIs, agreed mapping, error handling and tests. Monthly care starts from £199/month. Prices exclude VAT. Required licences, hosting and usage are confirmed separately before you commit. Care is optional after client-managed handover; additional development is quoted separately.

Yes. Softomate builds webhook integrations between SaaS platforms including Salesforce, HubSpot, Stripe, Zendesk, Microsoft Azure and custom applications. Webhook architecture uses event-driven HTTP POST calls to push data between systems the moment a trigger fires, rather than waiting for a scheduled batch. Softomate implements payload validation, signature verification, retry logic and dead-letter queuing to prevent data loss on failed deliveries. OAuth 2.0 or JWT tokens secure each webhook endpoint against unauthorised requests. UK GDPR controls filter personal data fields before payloads are forwarded to downstream systems. Softomate clients typically replace overnight batch sync delays with sub-sixty-second event propagation after webhook launch. A technical discovery session confirms trigger events, payload schemas and error-handling requirements.
