What happens next?
By securing a 0-0 draw in the second leg, Palace go through 1-0 on aggregate following Jean-Philippe Mateta's first leg winner.
The Eagles now join 23 other winners of play-off ties in the league phase. They will then be complimented by an additional 12 teams, who were eliminated in the Europa League play-off round.
These 36 clubs will contest the league phase. Rather than every side playing against each other, teams will play six fixtures in total. The six opponents of each club will be determined by a draw.
When is the draw for the next round?
The draw for the league phase will take place on Friday, 29th August in Monaco.
The UEFA Europa League and Conference League draws will take place together, as part of the same ceremony. This is expected to get underway at 12:00 BST.
The 36 clubs will be split into six pots of six, with each team drawn against one team from each pot. Kick-off times are not expected to given instantly, but will be released in due course over the following days.
Palace will be in pot 2 for the draw. Each side can play against a maximum of two opponents from any other one association.
