API Documentation

The DDB API is made up of a number of different microservices. Below you can see the different services you can interact with, along with how to authenticate and get access.

Microservices

Our API is segregated into microservices.

Microservice	Purpose
Comments Service	Hosts threaded comments that relate to a variety of systems, assets and parameters.
Environment Context Service	Stores the current projects in DDB and links to wider Arup systems via ADS.
Parameter Metadata Service	Provides metadata on assets and parameters on projects.
Parameter Service	Stores asset and parameter data on projects.
QA Service	Stores the QA data relating to parameters and entries.
Reference Data Service	Defines references to internal and external sources. Holds the sources of parameter values.
Taxonomy Service	Holds the DDB taxonomy.
Template Service	Holds template structures of parameters and assets that can be used for content creation and automated processes.
User Service	Manages users' roles on projects to define access permissions per projects.

Each microservice has an independent instance for each of the three environments. For a recap of the purpose of each environment, see here.

The following table includes links to each microservice, for each environment.

*Only the DDB Development team should be using the Development Environment

All the different services use the same base url (e.g. https://ddb.arup.com (opens new window)) and are routed to according to their url.

Each microservice is defined in using Open API 3.0 (Swagger). If you are unsure of API endpoints related to your process contact the Onboarding team for more support.
