• Supports various authentication and authorization setups.
• Highly configurable for real-world billing scenarios.
Technical Architecture
• SOAP/HTTPS-based communication.
• XML-based data structures, configured for real-time event exchanges.
• Comprehensive protocol specs for data routing and error handling.
Codibly’s OICP Integration Services
• Implementation consulting and architectural design.
• OICP-based backend integration for eMSPs and CPOs.
• Post-launch support covering updates, bug fixes, and performance tuning.

Throughout my career, I have consistently focused on delivering both off-the-shelf and custom solutions that address complex business challenges.
Frequently Asked Questions
Most mature Charge Point Operators (CPOs) need both. OICP connects you to the Hubject intercharge network, instantly giving you access to thousands of eMSPs via a single contract. OCPI is best for direct, bilateral Peer-to-Peer (P2P) connections with key strategic partners where you want to avoid roaming fees or implement custom tariff structures. Codibly’s architecture supports a hybrid model to maximize coverage while minimizing costs.
Our OCPI Accelerator is a pre-built, microservices-based module that handles standard handshakes, token exchange, and CDR (Charge Detail Record) pushing out of the box. Instead of building the protocol layer from scratch (typically 4–6 months), your team only needs to map your internal API to our connector, reducing deployment time to 4–8 weeks. It supports both OCPI 2.1.1 and 2.2.1.
Yes. We build custom Translation Layers (Adapters) that allow an OCPI-native backend to communicate seamlessly with OICP hubs like Hubject, and vice versa. This middleware handles the complex mapping of EVSE IDs, status codes, and error handling between the two protocols, ensuring your system remains the “Source of Truth” without needing a complete re-architecture.
Our implementation supports the transfer of signed meter values (transparency software data) required for German Eichrecht compliance. We ensure that the digitally signed data tuples from the hardware are passed intact through the OCPI/OICP layers to the eMSP for validation, ensuring that your billing records are legally defensible and audit-proof.
Yes. We support the Tariff Module and Charging Profiles in OCPI 2.2.1. This allows CPOs to push dynamic, time-of-use pricing to eMSPs in real-time. It also enables Smart Charging commands, allowing the eMSP to request specific power limits during a session (e.g., for grid balancing services) if the commercial agreement permits it.
