62012 Software Development Automation & Connected Systems Service 04

API-Connected Portals & Data Hubs

A platform that brings together information or functions held in several compatible services, so that one place answers the question instead of four. What is possible is defined by what each provider's interface and terms actually permit.

Multiple software systems and data sources connecting into a secure central portal and data hub.

The situation this service is built for

An organisation runs several good systems that do not speak to each other. Orders sit in one place, invoicing in another, customer communication in a third, and delivery information with a supplier. Each system is fine on its own; together they force people to become the integration layer.

The symptoms are familiar. Somebody exports a report weekly and pastes it into a spreadsheet. Customers ask a question that requires two people and three logins to answer. A number that should be identical in two places is not, and nobody knows which is correct.

A connected portal or data hub gives one controlled place where the relevant information is brought together, kept current within defined limits, and shown to the right audience — internal team, customer, or partner — with appropriate access.

This service is also where realistic expectations matter most, because the constraint is rarely the code. It is what each provider permits.

Problems this service may address

  • The same information lives in several placesCopies drift apart and reconciling them becomes a recurring administrative task.
  • Manual export and import cyclesRegular downloads and uploads between systems, performed by a person who could be doing something else.
  • Customers cannot see their own statusEvery status question becomes a support contact because the information is not exposed anywhere.
  • Partners need a controlled viewSuppliers or partners need some information but not all of it, and email is the current access control.
  • Reporting spans systemsProducing a single figure requires pulling from several sources and assembling it by hand each time.
  • Access is all or nothingGranting somebody one piece of information means giving them a full account in a system they should not see.

What a connected platform can contain

Possible applications

  • Customer portals showing relevant records
  • Partner workspaces with controlled visibility
  • Data aggregation from several sources
  • Connected dashboards
  • Synchronised records between systems
  • Service integrations for specific functions
  • Structured data exchange between organisations
  • Secure access to selected information

Typically included in scope

  • Integration feasibility assessmentEstablishing what each provider's interface exposes and what its terms allow, before commitment.
  • Data mappingHow fields in one system correspond to fields in another, including where they do not correspond neatly.
  • Synchronisation designDirection, frequency, and which system is authoritative when two disagree.
  • Access modelWho sees what, at what level of detail, and how access is granted and revoked.
  • Portal or hub developmentThe interface where the connected information is presented and used.
  • Failure handling and monitoringWhat happens when a provider is unavailable, and how that becomes visible rather than silent.

Assessment before confirmation. Third-party compatibility, access permissions, API limitations, licence costs and provider terms must be assessed before project confirmation. Universal compatibility is not claimed, and any integration that proves unviable is reported with the reason rather than worked around silently.

What is not automatically included

  • Third-party licence and API costsProvider subscriptions, higher-tier plans required for API access, and per-call charges are the client's costs and are identified during assessment.
  • Building interfaces where none existWhere a system exposes no usable interface, integration may be impossible. Screen-scraping is not offered as a substitute.
  • Changes to third-party systemsConfiguration or development inside another provider's product is outside this scope.
  • Ongoing responsibility for provider changesProviders alter their interfaces. Adjusting to those changes after handover is a support arrangement, not part of the build.
  • Historical data reconciliationBringing existing records in the two systems into agreement before synchronisation begins is separate work.
  • Guaranteed real-time synchronisationFrequency is limited by what the provider's interface allows; agreed intervals are stated rather than promised as instantaneous.

Engagement process

Stage 01

System inventory

Listing the systems involved, what each holds, who administers it, and which plan or licence the organisation currently holds — because API access is frequently tied to plan level.

Stage 02

Feasibility assessment

Each intended connection is checked against the provider's documentation and terms: available fields, rate limits, authentication method, permitted use and cost. The result is a written viability statement per connection.

Stage 03

Data mapping and proposal

Field-by-field mapping, direction of flow, conflict rules and update frequency. The written proposal states which connections are in scope, which were found unviable, and the price.

Stage 04

Connection build and hardening

Integrations are developed with retry handling, rate-limit respect and logging. A connection that works only when everything is available is not finished.

Stage 05

Portal build and access control

The interface is developed with the agreed access model, so each audience sees exactly the information intended for it and nothing beyond.

Stage 06

Testing, monitoring and handover

Testing includes provider-unavailable scenarios. Monitoring is configured so failures are noticed, and documentation covers credentials, renewal and what each connection depends on.

Expected deliverables

  • The working portal or hubDeployed to the agreed environment with the agreed access model in place.
  • Integration documentationEach connection recorded: provider, authentication method, fields, direction, frequency and known limitations.
  • Data mapping referenceHow fields correspond across systems, including transformations and the fields deliberately excluded.
  • Feasibility recordWhat was assessed, what proved viable, and what did not — with reasons, retained for future reference.
  • Failure and recovery notesWhat happens when a provider is unavailable, and how to recover once it returns.
  • Source code for the custom workDelivered in a repository, with ownership addressed in the written agreement.

Client responsibilities

  • Administrative access, or an administrator's cooperation, for every system to be connected
  • Authority to accept each provider's API terms and any associated costs
  • A decision on which system is authoritative where two hold the same information
  • Confirmation of who may see which information, before the access model is built
  • Secure handling of credentials and API keys, and a named owner for their renewal
  • Acceptance that some intended connections may prove unviable, and a view on the alternative

Factors that affect scope and price

Increase scope

  • Each additional system connected
  • Two-way synchronisation rather than read-only display
  • Conflict resolution where both systems may be edited
  • Providers with restrictive rate limits requiring careful scheduling
  • Several audiences with different access rules
  • Poorly documented or unstable provider interfaces

Keep scope lean

  • Read-only display before attempting synchronisation
  • One or two well-documented providers to begin with
  • A single clear source of truth for each piece of information
  • Scheduled updates rather than immediate propagation
  • One audience at launch, with others added later

Pricing notice. All prices are indicative starting points. Final pricing depends on project scope, complexity, integrations, documentation, timescale and agreed deliverables. Applicable taxes and third-party costs are confirmed in the written proposal where relevant.

After delivery

Settling period

A defined period after handover during which behaviour that does not match the agreed specification is corrected at no additional charge.

Connection maintenance

Providers change their interfaces, sometimes with short notice. An agreed arrangement covers responding to those changes; without one, they are handled as change requests.

Additional connections

Once the hub exists, adding a further source is usually a smaller piece of work than the first one was.

Questions about this service

Service enquiry

List the systems. The rest follows from what they permit.

Name the systems involved, what information should move between them and who needs to see it. Feasibility can usually be assessed quickly from that.
