| Name | Description | 
|---|---|
| مطلوب api_key | Your API key (required unless you're using HTTP basic authentication) | 
| مطلوب {tournament} (in URL string) | Tournament ID (e.g. 10230) or URL (e.g. 'single_elim' for challonge.com/single_elim). If assigned to a subdomain, URL format must be :subdomain-:tournament_url(e.g. 'test-mytourney' for test.challonge.com/mytourney) | 
| مطلوب {participant_id} (in URL string) | The participant's unique ID | 
| participant[name] | The name displayed in the bracket/schedule - not required if email or challonge_username is provided. Must be unique per tournament. | 
| participant[challonge_username] | Provide this if the participant has a Challonge account. He or she will be invited to the tournament. | 
| participant[email] | Providing this will first search for a matching Challonge account. If one is found, this will have the same effect as the "challonge_username" attribute. If one is not found, the "new-user-email" attribute will be set, and the user will be invited via email to create an account. | 
| participant[seed] | integer - The participant's new seed. Must be between 1 and the current number of participants (including the new record). Overwriting an existing seed will automatically bump other participants as you would expect. |
