API development London refers to building REST APIs, GraphQL endpoints, webhook architectures and middleware layers that connect business software automatically. London operations directors, IT leads and finance teams at UK mid-market firms benefit most when disconnected SaaS platforms create manual re-entry, reporting delays and data inconsistencies. Softomate builds bespoke API integrations connecting Salesforce, SAP, HubSpot, Stripe and Microsoft Azure through OAuth 2.0 and OpenAPI/Swagger-documented endpoints. Teams needing broader automation can pair API delivery with our AI process automation services, business process automation services, AI and machine learning solutions, and bespoke software development services.
01. Key Benefits
REST API integrations replace daily manual copy-paste between Salesforce, SAP and back-office tools, cutting data entry errors and freeing staff for higher-value work.
Webhook event triggers and OAuth 2.0 connections replace overnight batch imports, syncing records across Salesforce, HubSpot and Stripe in under sixty seconds after each event.
UK GDPR data minimisation, TLS 1.2 encryption and audit logging are built into every integration, giving compliance teams exportable evidence for ICO or FCA reviews.
OpenAPI/Swagger specifications and Postman test collections are delivered with every project, so internal developers and future teams can extend integrations without reverse-engineering.
API-first architecture on AWS or Microsoft Azure scales with transaction volume, so integrations remain stable as your UK business grows without rebuilding from scratch.
Automated data flows between finance, CRM and ERP platforms reduce reporting cycle time from several days to same-day, giving leadership accurate figures without manual consolidation.
02. Offerings
Operations and product teams get bespoke REST APIs and GraphQL endpoints with OpenAPI/Swagger documentation, JWT authentication and full Postman test suites. Versioned endpoints, error schemas and rate-limiting rules keep integrations stable as connected platforms evolve and data volumes grow.
Finance and CRM teams get real-time connections between Salesforce, SAP, HubSpot and bespoke platforms through OAuth 2.0 and vendor REST APIs. Field mappings, transformation logic and error-handling queues are delivered with UAT sign-off, so data quality stays consistent across all connected systems.
Development and IT teams get webhook pipelines that push event data between SaaS platforms in near real time, replacing overnight batch sync delays. Payload validation, signature verification, retry logic and dead-letter queuing prevent data loss when downstream services are unavailable during peak traffic.
Compliance and security teams get OAuth 2.0 authorisation flows, JWT token validation and scoped permission management for every external-facing API. UK GDPR data access controls align with OAuth 2.0 permission scopes, limiting which personal data fields each integration can read or write.
IT and operations teams get middleware orchestration layers, endpoint health monitoring and alert routing for production API environments on AWS or Microsoft Azure. Monthly support agreements cover token refresh management, version updates, error-log reviews and capacity planning as connected platform usage grows.
03. Features
Every endpoint is documented with request schemas, response codes, error models and authentication requirements for handover to internal developers.
Scoped access tokens, refresh token rotation and JWT claim validation protect every external API connection against unauthorised access.
Exponential back-off retry logic and dead-letter queuing prevent data loss when downstream services are temporarily unavailable during high-traffic periods.
TLS 1.2 encryption, data minimisation rules and audit logging are applied to every API handling personal data under UK GDPR and ICO guidelines.
Automated Postman test suites cover happy paths, error conditions and edge cases, giving QA and development teams repeatable regression coverage after launch.
Uptime alerts, latency dashboards and error-rate tracking on AWS or Microsoft Azure give operations teams early warning before integration failures reach end users.
05. Process
Softomate maps data flows, agrees endpoint contracts, builds authenticated integrations and delivers documented handover in short delivery phases. Client IT leads, operations managers, data owners and compliance contacts stay involved from discovery through launch, so integration decisions match security, reporting and UK GDPR requirements.
Platform architecture, data flows and UK GDPR obligations are mapped in discovery workshops with IT leads, data owners and operations managers. Discovery produces a technical requirements brief, data-flow diagram and integration inventory covering Salesforce, SAP, HubSpot or bespoke back-office systems.
Endpoint contracts, OpenAPI specifications and authentication patterns are agreed with stakeholders, security contacts and platform owners during planning. Planning produces a delivery roadmap, field-mapping document and acceptance criteria covering OAuth 2.0, JWT and UK GDPR data controls.
API schemas, data transformation rules and error-handling models are designed with platform owners, developers and compliance contacts. Design produces approved endpoint specifications, webhook payload schemas and security architecture for Salesforce, SAP, Stripe or Microsoft Azure environments.
Working REST API endpoints, OAuth 2.0 flows, webhook pipelines and data transformation logic are built in short sprints with client IT contacts. Build work produces a staging integration, Postman test collections, UK GDPR audit controls and monitoring events across connected platforms.
Production deployment, endpoint health monitoring and handover documentation are completed after UAT sign-off with IT contacts and data owners. Launch work produces OpenAPI documentation, Postman collections, monitoring dashboards and a support backlog for token management, version updates and capacity planning.

09. FAQs
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.
Softomate REST API and system integration projects for UK companies typically start at ΓΒ£4,000 and rise with endpoint complexity, third-party platform count and compliance scope. A focused two-platform integration with standard OAuth 2.0 authentication costs less than a multi-system middleware layer connecting Salesforce, SAP and Stripe. GraphQL API development, real-time webhook architectures and custom data transformation pipelines increase build effort. UK GDPR audit logging, encryption controls and subject access request workflows add scope when personal data flows cross system boundaries. Ongoing costs usually cover monitoring, token refresh management and endpoint version updates. Softomate quotes fixed project pricing after discovery, so scope and outputs stay clear throughout delivery. A short technical discovery session produces a defined budget range before any build work starts.
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. Explore our <a href="/ai-process-automation/">AI process automation services</a> to extend webhook triggers into automated decision workflows. A technical discovery session confirms trigger events, payload schemas and error-handling requirements.
