Add product image via webservice

[eggandspam]

I set up a webservice key that has image and products full permissions. But when pass a POST request to add a image to a product, for example /api/images/products/1, the server response is code 66 message Unable to save this image, no further info.

 

Checking the back access we have the following:

GET api/

<images xlink:href="http://192.168.56.101/tienda/api/images" get="true" put="true" post="true" delete="true" head="true">

GET api/images/

<products xlink:href="http://192.168.56.101/tienda/api/images/products" get="true" put="false" post="false" delete="false" head="true" upload_allowed_mimetypes="image/gif, image/jpg, image/jpeg, image/pjpeg, image/png, image/x-png"/>

 

For that reason I think is a permission issue but I can't find any documentation that help me. My question is, what permission is need it to have PUT and POST methods over the /images/products resource?

above script will download an image from an URL and add to a prestashop product through webservices API

Hi,

i'am ok on POST an image but if i want to PUT a new image for the product nothing seem to work, can you explain how to update an image for the product ?

above code is for uploading products to product id 4

 

see this   $url = PS_SHOP_PATH. '/api/images/products/4';

In php>5.5 you have to use curl_file_create instead of this:

curl_setopt($ch, CURLOPT_POSTFIELDS, array('image'=>"@".$img_path.";type=image/jpeg"));

I've tried  this:

$cfile = curl_file_create($img_url,'image/jpg','image');

curl_setopt($ch, CURLOPT_POSTFIELDS, $cfile);

but the response return me the error "Unable to save this image".

Do you have an idea of how could I solve the problem?

[AlbertoV]

Does someone had success in editing the images using the webservice?

I still trying to do that. I receive 200 response, but the image still the same.
