I am developing an integration between several systems and in one point I have to find the files inside a folder using the SharePoint REST API. The data I have to look for the folder is the List were it is and an attribute named "Código de material". I am by no means a SharePoint expert. So, I am sorry beforehand for the terms mistakes.
I have been trying with a few REST method but to no avail. For example:
returns this error message
<m:error xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"> <m:code>-1, Microsoft.SharePoint.Client.InvalidClientQueryException</m:code> <m:message xml:lang="es-ES">La expresión "Código de Material='000000000000401426'" no es válida.</m:message> </m:error>
What would be the correct way to filter a list by a given folder attribute?
FWIW I am using Java but the question is about the REST call really.
