Safe Stamper Web API callbacks

When starting a certification job with stamp you can provide a callback URL.

Once the certification job is finished, the callback URL will receive a POST call with the same JSON object as returned in the status operation.

To authenticate the callback, the JSON object HMAC-SHA1 will be calculated using the API client private key and will be provided as a query string signature parameter.

Example

Line breaks have been included in this example content for legibility, but actual callbacks include the whole JSON in a single line.
