Restrict Uploads Using File Extensions
This article demonstrates how to restrict file uploads based on file extensions.
Uploads can be restricted as follows:
Using SharinPix Permission Records
SharinPix Permission records consist of the Accepted file types parameter used to specify the type of files that can be uploaded to an album.
The Accepted file types parameter takes as value the list of accepted file extensions separated by a semi-colon.
For example to restrict uploads to .jpeg, and PDF files, the value will be as follows: .jpeg;application/pdf
Tips:
- The application/pdf extension is used in the Accepted file types parameter to enable the upload of PDF files.

Using the upload_accept parameter in Apex Method
Online tokens can be used to restrict uploads based on file extensions using the upload_accept parameter which specifies the type of files that can be uploaded to an album.
For example, to restrict uploads to .png and .jpeg files, the value will be as follows:
'upload_accept' => new List <String> { '.png', '.jpeg' }
The code following code snippet demonstrates how to generate an online token with the upload_accept parameter.
public String generateToken(Id recordID) {
sharinpix.Client clientInstance = sharinpix.Client.getInstance();
String token = clientInstance.token(
new Map<String, Object> {
'Id' => recordID,
'upload_accept' => new List <String> { '.png', '.jpeg' },
'path' => '/pagelayout/' + recordID,
'abilities' => new Map<String, Object> {
recordID => new Map<String, Object> {
'Access' => new Map<String, Boolean> {
'see' => true,
'image_list' => true,
'image_upload' => true
}
}
}
}
);
return token;
