ABSTRACT

To become a participant of Catena-X, each applicant must go through a registration process. Registration is a mandatory requirement for all further activities within the Catena-X network. The registration process, along with other services, provide the foundation of trust for the Catena-X network.

The Registration & Administration Service describes the endpoints that are needed for the registration process.

1. Introduction

To become a participant of Catena-X, each applicant must go through a registration process. Registration is a mandatory requirement for all further activities within the Catena-X network. The registration process, along with other services, provide the foundation of trust for the Catena-X network.

1.1 Audience & Scope

This section is non-normative

This standard is relevant for the following roles:

• Core Service Provider
• Onboarding Service Provider (for reference)

1.2 Context

This section is non-normative

The registration API is used as part of the registration process.

1.3 Architecture Overview

This section is non-normative

A core service provider operates among other things a registration frontend through which a registering company can enter its data. In the future, the registration service may be accessed remotely, for example by onboarding service provider, so the API needs to be standardized.

1.4 Conformance

As well as sections marked as non-normative, all authoring guidelines, diagrams, examples, and notes in this specification are non-normative. Everything else in this specification is normative.

The key words MAY, MUST, MUST NOT, OPTIONAL, RECOMMENDED, REQUIRED, SHOULD and SHOULD NOT in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.

1.5 Proof of conformity

This section is non-normative

All participants and their solutions will need to proof, that they are conform with the Catena-X standards. To validate that the standards are applied correctly, Catena-X employs Conformity Assessment Bodies (CABs).

Core service providers implementing their own registration solution MUST proof their conformity by providing:

• An openAPI specification of the endpoints described

1.6 Terminology

This section is non-normative

Application Programming Interface (API)

An application programming interface (API) is a way for two or more computer programs to communicate with each other.

Additional terminology used in this standard can be looked up in the glossary on the association homepage.

2. Catena-X Registration API

2.1 Preconditions and dependencies

The registration API is exposed to the Internet.

2.2 API Specification

2.2.1 API-Endpoints - Core Service Provider

The Core Service Provider MUST implement the following endpoints -- in focus are the API business logic / content and structure, the path name might change / be different but the business logic behind as well as the attributes must be followed. Details to the respective MUST and SHOULD statements may be found below.

Note functional description and standard definition of the CSP role are defined inside the standard CX-0006-RegistrationAndInitialOnboarding.
