Error sending image to pinterest by url using Token

Hello friends, I'm trying to send an image to pinterest as follows:

https://api.pinterest.com/v1/pins/?access_token=******&fields=id%2Ccreator&link=https://localhost/&image_url=http://3.bp.blogspot.com/-cP9MUDC3OJ0/W8LoDjVkavI/AAAAAAAAL9o/qhe9uf069AgvIj1QHXpcpmOlmLxsYmn6wCK4BGAYYCw/s1600/294315_349074945197846_37345677_n-745549.jpg&board=chicas/chicas-malas&note=SAVE

based on the information provided by your Pinterest Api page. The problem is that he always shows me the following error:

{
  "message": "405: Method Not Allowed", 
  "type": "http"
}

and I can not find out what the error is. I hope you can give me some idea or information
