Payment gateway integrations
Connect an approved provider, transaction status, reconciliation and payment exceptions.
Backend API integrations
Payment gateways, CRM/ERP/IVR bridges, REST, GraphQL and microservices.
Operating context
Scope around your business.
Connected systems need clear API boundaries, reliable data contracts and owned error handling. Rektrs develops integration services around the business transaction rather than treating every connection as an isolated script.
Intended outcome
A business-aligned solution with agreed validation evidence and an owned operating model.
CRM/ERP/IVR bridges
Join customer, business and voice systems with agreed record ownership.
Third-party APIs, REST & GraphQL
Implement scoped API connections, access controls, validation and integration records.
Microservices architectures
Design service boundaries, messaging and observability where the operating model warrants them.
Engagement priorities
- Agreed scope, owners and acceptance criteria
- Integration, access and data responsibilities
- Documentation, handover and support planning
Plan your engagement
Backend APIs and business system integrations
Backend API integration connects approved payment, CRM, ERP, IVR and third-party systems through defined data contracts. Rektrs plans authentication, validation, record ownership and failure handling for REST, GraphQL or service-based interfaces.
What should we provide before an integration is scoped?
Share interface documentation, sandbox access, sample records, volume expectations and permitted actions. Identify which system owns each field and whether historical data must be reconciled.
How are duplicate records and failed transactions handled?
Define identifiers, retry behavior, validation rules and exception queues. For payments, reconcile provider status with business records rather than treating a browser success message as the final result.
Before implementation
Agree the work. Define the evidence.
We confirm your current systems, locations, process owners and required outputs. The proposal sets milestones, dependencies, acceptance criteria and support responsibilities for the agreed scope.
