Description

Sets a user's RSVP status for an event. An application can set a user's RSVP status only if the following are all true:

  • The application is an admin for the event.
  • The application has an active session for the user.
  • The active user has granted the application the rsvp_event extended permission.

Parameters

RequiredNameTypeDescription
required api_key string The application key associated with the calling application. If you specify the API key in your client, you don't need to pass it with every call.
call_id float The request's sequence number. Each successive call for any session must use a sequence number greater than the last. We suggest using the current time in milliseconds, such as PHP's microtime(true) function. If you specify the call ID in your client, you don't need to pass it with every call.
session_key string The session key of the logged in user. The session key is automatically included by our PHP client.
sig string An MD5 hash of the current request and your secret key, as described in the How Facebook Authenticates Your Application. Facebook computes the signature for you automatically.
v string This must be set to 1.0 to use this version of the API. If you specify the version in your client, you don't need to pass it with every call.
eid int The event ID.
rsvp_status string The user's RSVP status. Specify attending, unsure, or declined.
optional format string The desired response format, which can be either XML or JSON. (Default value is XML.)
callback string Name of a function to call. This is primarily to enable cross-domain JavaScript requests using the <script> tag, also known as JSONP, and works with both the XML and JSON formats. The function will be called with the response passed as the parameter.

Response

This method returns true if successful.

Error Codes

CodeDescription
1 An unknown error occurred. Please resubmit the request.
2 The service is not available at this time.
4 The application has reached the maximum number of requests allowed. More requests are allowed once the time window has completed.
5 The request came from a remote address not allowed by this application.
101 The API key submitted is not associated with any known application.
102 The session key was improperly submitted or has reached its timeout. Direct the user to log in again to obtain another key.
103 The submitted call_id was not greater than the previous call_id for this session.
104 Incorrect signature.

Notes

You can call this method using a session secret, and not the application secret (for example, for a Facebook Connect site or desktop application).
