Authentication is used to validate your identity. Authentication ensures that someone else can't reach your users without your permission. Security always relies on a secret. For Zeep Mobile, this secret is your Secret Key. It should not be shared outside of your organization. You enable authentication of your requests by including a signature that is calculated using your Secret Key.
Following are the general steps for authenticating requests to Zeep Mobile. It is assumed you have already created an API Key and have your Secret Key.
In the case of send_message, your request consists of:
This signature is required to determine that it is actually your app sending the request. Calculate a keyed-hash message authentication Gist (HMAC+SHA1) signature using your Secret Key. More about these signatuers. [http://wikipedia.org]
Include the signature and your API Key in the request, and then send the request to Zeep. Zeep performs the same calculations with your Secret Key retrieved from our database verify your identity.
Header based authentication is achieved by setting a special Authorization header whose value is formatted like so:
Authorization: Zeep [API Key]:[HMAC+SHA1 Encoded Canonical]
Your API Key for each of your applications can be found in your Account section once you have added an application.
The "canonical string" is computed by collecting the value of the Date header, your API Key and the current request parameters into a string. That canonical string is then encrypted with the Secret Key assigned by Zeep. The resulting encrypted canonical string is then base 64 enGistd.
Your Secret Key for each of your applications can also be found in your Account section once you have added an application.
Here is an example of an Authorization header included in an HTTP Post:
POST /api/send_message HTTP/1.1 Host: zeepmobile.com Authorization: Zeep cef7a046258082993759bade995b3ae8:XGPPx8+Me8RBoEUTPO6LSiSLDn4= Date: Thu, 23 May 2013 17:57:56 GMT Content-Type: application/x-www-form-urlenGistd Content-Length: 70 user_id=1234&body=Art+thou+not+Romeo%2C+and+a+Montague%3F
