An event ID is a 3-part unique event identifier. The DDE uses them to identify each single event that happens on the platform. ## Example Event ID Example ID: 2024-0083-MD013 **2024**\ This is the year the event takes place **0083**\ This is the Competition ID **MD013**\ This is the match ID. Match IDs are structured as follows: MD - The draw that the match is from\ 013 - The place of the match within the draw See below for a full breakdown of these for the **main** draws within tennis tournaments | Acronym | Type | | ------- | ------------------------------------------ | | MS | Men's Singles | | QS | Qualifying Men's Singles | | MD | Men's Doubles | | QD | Qualifying Men's Doubles | | LS | Ladies' Singles | | RS | Qualifying Ladies' Singles | | LD | Ladies' Doubles | | RD | Qualifying Ladies' Doubles | | XD | Mixed Doubles | | MX | Mixed Doubles - Hopman Cup/United Cup only | | Tournament Round | DDE Round | Event ID's | | ---------------- | --------- | ---------- | | Final | Round 1 | 001 | | Semi Final | Round 2 | 002 & 003 | | Quarter Final | Round 3 | 004 to 007 | | Round of 16 | Round 4 | 008 to 015 | | Round of 32 | Round 5 | 016 to 031 | | Round of 64 | Round 6 | 032 to 063 | | Round of 128 | Round 7 | 064 to 128 | N.B, the above are valid for the main draw of knockout tournaments. Qualifying draws will not end in a single match (001) - there will be 2 or more qualifiers progressing through to the main draw. Also, round robin tournaments will of course have a slightly different structure to the above, depending on how big the groups are. However, the Final will always be 001 and the Semi Finals 002 and 003 within a Round Robin tournament. --- # Agent Instructions This documentation is published with GitBook.
