Our jQuery library supports deleting resources on the client-side for a limited time of 10 minutes after being uploaded. After 10 minutes has passed, the image won't be able to be deleted from the client side, only via authenticated API.
When uploading, set the return_delete_token to true in order to tell Cloudinary to return a deletion token in the upload response, use the returned token to delete the uploaded image using an unauthenticated API request.
This is done with the delete_by_token method (of the jQuery library).

I can't get the delete_token! :'(
I upload the image this way :
$scope.uploadImages = function() {
var folder = '/va/bikes/'+$scope.bike._id;
cloudinary.openUploadWidget({
folder: folder,
cloud_name: 'www-despertaweb-cat',
upload_preset: 'bikes_preset',
theme: 'minimal',
thumbnails: 'img-responsive',
return_delete_token: true
},
function(error, result) {
console.log('\n\n Result', result);
for(var i in result){
$scope.bike.imgs.push(result[i]);
};
$scope.$apply();
});
};
Hi, it seems that you didn't set the "Return delete token" field to True on your "bikes_preset" upload preset. Could you please verify that?
In case it's useful to a future reader, I was personally finding it difficult to find the API endpoint that would allow me to delete using a delete_token, I found it helpful to reference this code in cloudinary jquery library, https://github.com/cloudinary/cloudinary_js/blob/6eac8e5233e6c04e772dcc0f991d28ae4d668c2a/src/jquery-file-upload.coffee#L14
In the end it's a POST to 'https://api.cloudinary.com/v1_1/' + cloud_name + '/delete_by_token', with parameters of `public_id` and `token`.
not work any more
Return in the header....
X-Cld-Error:Return delete token parameter is not allowed when using unsigned upload. Only upload_preset,callback,public_id,folder,tags,context,face_coordinates,custom_coordinates upload parameters are allowed.
Hi Accion,
I could delete the image with the unsigned upload preset "return delete token" set to "true" in Upload Preset on my account.
Could you please verify the unsigned upload preset you are using has "return delete token" set to "true" in media library settings page.
You can raise a support ticket here - https://support.cloudinary.com/hc/en-us/requests/new if it still doesn't work and I can take a deeper look at the code.
This "return delete token" set to "true" in Upload Preset on my account. is not available i can't see it at all been searching for hours now on the dashboard nothing. Really unprofessional and even if i want to use the public id to delete i get 401 signature problem. I post my the image signature and public id and api_key but it is not working.:S
i use URL from browser client
Okay i found how to do this return token thingy :
1.open dashboard.
2.click settings then Upload presets:
3.click edit
Hi Hesham, I glad you find the solution. Please let me know if you need any help. Thanks, Yakir
Do you have any plans or ability to bring this functionality to React?
Hi John,
The strategy here, of requesting a deletion token and using that in a subsequent API call to delete the image after it was uploaded, should work in any client-side framework, including React.
We don't have specific support for this in the React SDK so you'd need to make an HTTP request to the API endpoint manually: https://cloudinary.com/documentation/upload_images#deleting_client_side_uploaded_assets
Generally speaking, we don't intend to add support in the client-side SDKs for destructive actions because almost all other cases would require the API secret to be in the application code, which is not recommended for security reasons
If you'd like assistance with making the API calls from React, please open a support request with information about your current workflow and we'd be happy to advise
Thanks,
Stephen
