Yes — CSG offers 150+ out-of-the-box connectors covering the most common enterprise systems, so there's a strong foundation to build from. That said, in most enterprise environments some custom work is still needed due to unique objects, custom fields, and legacy constraints. Our approach is to start with what's available out of the box and identify any gaps during discovery, so you get a clear picture of what integration looks like in your specific environment before we scope anything.

CSG's APIs are built to meet SOC 2 Type II, PCI DSS, GDPR, CCPA, and HIPAA standards where applicable. Data is encrypted in transit using HTTPS/TLS 1.2 and at rest using AES-256. API security follows OWASP API Security Top 10 guidelines, and all API calls are logged, rate-limited, and monitored for abuse, with audit logs retained for at least 12 months.

Getting started is straightforward. For payment APIs, developers receive a platform invite, register for an account, generate API credentials, create authentication headers, and run test transactions before going live. Comprehensive developer documentation, sandbox environments, and dedicated support resources are available to guide teams through each step of the integration process.

Anywhere from weeks to a few months — it depends on scope, system count, and how much customization is in your environment. What we commit to is a real plan, not a placeholder. Once we confirm scope, we align to your change windows and give you defined milestones for build, testing, and cutover.

During integration, dedicated teams provide technical support throughout design, development, system integration testing (SIT), and user acceptance testing (UAT). After go-live, an early in-life support period covers production defect investigation and resolution, with ongoing support accessible via 24/7 chat or an online ticketing portal depending on the agreement in place.

CSG's platforms hold 11 TM Forum certifications — 9 for Open APIs and 2 for Business Process and Information Frameworks. Certified APIs span product catalog, product ordering, product inventory, customer management, payment management, geographic address management, and service inventory, among others. The platform is also an active TM Forum member and signatory of the Open API and Open Digital Architecture Manifestos.
