SSL is now required for all requests to the BigOven API. So precede your requested endpoint with "https://api2.bigoven.com"
Pass your API Key with Every Request
You'll be passing your API key, issued to you when you're approved to use the API, with every request, as the parameter api_key, or if you'd prefer, via the request header with a key named "X-BigOven-API-Key".
In addition, if you'd like to do things at the BigOven.com user level, like see your favorites or post a review on behalf of a user, you'll need to pass authentication information for that BigOven user. That's different than your api_key; it's an encoded version of the user account information that you'll need to put in the request header.
The authentication process for this user-level part of the BigOven API is based on the HTTP Basic Access Authentication method defined by RFC 1945 (Hypertext Transfer Protocol – HTTP/1.0).
Every API call that requires user level permissions must be made with a correctly
set HTTP “Authorization” header. This header presents the user’s credentials to
the api.bigoven.com server in Base64 format which can then be decoded by BigOven for verification.
The following template demonstrates the process of generating the Authorization header for a given username and password combination. This simple example, taken from RFC 1945, considers a username “Aladdin” with the password “open sesame”.
|3||Combined String||Aladdin:open sesame|
|4||Base64 Encoded Combined||QWxhZGRpbjpvcGVuIHNlc2FtZQ==|
|5||Authorization Header||Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==|
GET /private/index.html HTTP/1.0 Host: localhost Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==Fortunately for the API Client, most languages make both Base64 encoding and setting the Authorization header on a request a trivial process.
Pass Authentication Information using the Authorization Request Header
It is worth noting that not every API call requires the Authorization header to be set. BigOven public data may be requested without user credentials.
Generally, you'll want to pass authentication information to api2.bigoven.com whenever you're doing something on the user's behalf, like posting a review, or fetching the profile of the currently logged in user. General operations, like searching recipes, don't require user-level authentication. Remember that the user information you're passing isn't your user information as a developer, it's that of the user, which you collect in a login dialog and then Base64-it as above to pass to BigOven.com for authentication.
