When using an API-led approach, what is the first design document the travel company should deliver to its business partners?

A travel company wants to publish a well-defined booking service API to be shared with its business partners. These business partners have agreed to ONLY consume SOAP services and they want to get the service contracts in an easily consumable way before they start any development. The travel company will publish the initial design documents to Anypoint Exchange, then share those documents with the business partners.

When using an API-led approach, what is the first design document the travel company should deliver to its business partners?
A . Create a WSDL specification using any XML editor
B . Create a RAML API specification using any text editor
C . Create an OAS API specification in Design Center
D . Create a SOAP API specification in Design Center

Answer: A

Explanation:

SOAP API specifications are provided as WSDL. Design center doesn’t provide the functionality to create WSDL file. Hence WSDL needs to be created using XML editor
