API Development & Integrations

REST, GraphQL, payments, ERP, CRM, and public-sector APIs.

Overview

We design REST and GraphQL APIs, payment gateway integration, ERP and CRM integration, and banking, healthcare, and government APIs. Integrations are treated as products: versioned, observed, and documented.

Problems we solve

  • Systems that only connect through file drops and email
  • A payment flow bolted on without a clear failure path
  • ERP or CRM as a bottleneck because nothing else can talk to it
  • Partner APIs that break silently when a field changes

Our approach

  1. 01Model the contract first — resources, errors, and idempotency
  2. 02Integrate payments, ERP, and CRM with explicit mapping
  3. 03Respect industry API constraints in banking, health, and government
  4. 04Add monitoring and versioning so consumers are not surprised

Capabilities

  • REST and GraphQL APIs
  • Payment gateway integration
  • ERP and CRM integration
  • Banking, healthcare, and government APIs

Benefits

  • — One integration layer instead of point-to-point chaos
  • — Payments and core systems that fail loudly and recover
  • — Room to add partners without rewriting the core
  • — APIs that other REPLA products can share

FAQ

Both are in the catalog. We pick from consumer needs, caching, and how the domain is queried.

Yes. ERP and CRM integration is a listed capability, including when REPLA did not build the system of record.

Yes. Payment gateway integration is a listed capability. We design clear success and failure paths so retries and refunds are not left to chance.

Yes. Banking, healthcare, and government APIs are listed. We respect industry constraints on auth, audit, and data handling as part of the contract design.

We treat integrations as products: versioned contracts, monitoring, and documentation so consumers are not surprised when a field or behavior changes.
