There is a list of all the objects which can be accessed by REST for CRUD in this link: REST API - Documentation for Core Objects under the Core Objects section.
For each of the objects listed under the Core Objects section are there is a field metadata under the Properties section.
For example for Email object, REST API - Accessing Emails , under the Properties section, there corresponding entries for fields of Emails object under the
Name ,Type, Description and Validations headings.
Is there a REST API for retrieving the same information i.e. the field metadata for an eloqua object programmatically ?
If not , it is a serious hindrance to building systems that are metadata driven and also since SOAP support is being deprecated...
