Sort your parameters alphabetically by name. For example, if you are trying to retrieve a list of files in a particular location and use the following parameters:

• path: “%2F” (the url-encoded version of "/")
• sort_by: “date_asc”
• api_key: “key”

You would form your URL as such:

https://<your subdomain>.<your domain>/api/file_list?api_key=key&path=%2F&sort_by=date_asc&timestamp=<current time>

Using the URL, create a signature using HMAC-SHA256, using the SHA1 hash of your API secret as the key. An example in PHP would look like this:

$signature = hash_hmac(‘sha256’, <URL from above>, sha1(<your API secret>));

Add this signature as a parameter to the end of your URL like this:

https://<your subdomain>.<your domain>/api/file_list?api_key=key&path=%2F&sort_by=date_asc&timestamp=<current time>&signature=<signature>

Simply pass the URL of the API method into your HMAC-SHA256 signature creator. An example in PHP:

$signature = hash_hmac(‘sha256’, ‘https://<your subdomain>.<your domain>/api/file_upload’, sha1(<your API secret>));
