Managing API Namespaces

Create an API Namespace

To create an API Namespace, use the Create capability in the API Namespaces Overview section or in the Navigation.

An API namespace is defined by the following master data:


Property	Description
Prefix	This is the prefix of the API namespace. It is unique within an API solution. Please note that only the characters A-z (without special characters), digits and the special character "_" are permitted for a prefix! Furthermore, prefixes may not begin with a digit and the first character must be lowercase. A prefix can not consist more than 6 characters. The prefix cannot be changed after creation. This field is mandatory.
Label	This is a meaningful title of the API namespace. This field is mandatory.
Description	This is the description of the API namespace and its lifecycle. This field is optional.

Create API Namespace from Scratch

After selecting and confirming the “from scratch” option you have to provide the following metadata about the API.


Property	Description
API Title	Title of the API. This field is mandatory.
API Description	Description of the API. This field is optional.
HOST	Base URL for API calls. The host of the Server is only a placeholder and will be substituted depending to the deployment. The base path is prefilled with the prefix of the API Namespace This field is mandatory.
Contact E-mail	Contact E-mail of the API. A valid E-Mails must be provided. This field is optional.

By proceeding with next you can select the format for the API Specification (OpenApi 3.0 or Swagger 2.0) you want to generate and add additional Integration Artefacts that should be automatically produced during the build process of the solution. Create after that will persist the new API Namespace.

Create a new API Namespace based on an uploaded API Specification

After selecting “based on uploaded Open API/Swagger file" option you have to provide a API Specification (.yaml or .json) file and upload it. After confirming with 'Create' the uploaded file is first checked to be a valid Specification. If it's content is invalid a message is shown within the capability.

For API specifications currently the following content is supported to be imported to the new API Namespace.

Attention: If the uploaded API specification does not meet the above mentioned expectations completley a list of notifications is shown in order to indicated what should be changed within the spec file to meet the expectations.

During the import Financial Services Workbench auto-resolves the following issues if occuring to fit to the supported structure of the Design Environment:

Component identifier of every component is required to be capitalized and will be auto resolved to be capitalized.
Property name is required to start with a lowercase letter and will be auto resolved.
Content type ‘application/json; charset=utf-8’ is auto-solved to ‘application/json’.
Parameters with location ‘path’ will be skipped during the import.
Path URL is required to start with a ‘/’ which is automatically added during importing.
Path URL is required not to end with a ‘/’ which is automatically removed during importing .

Note: The information API title, API description, Host, Contact e-mail, Contact name, Contact URL, License name, License URL and Terms of service URL will be taken from the uploaded API specification and can be changed afterwards. After successfully creation of the API Namespace a confirmation is shown and the created elements of the API Namespaces are stated.
