Wrexham will host Eastleigh in the play-offs after Nicky Deverdics secured victory over Harrogate Town.
The Dragons finished fourth in the National League while Harrogate's sixth place means they will be away to AFC Fylde.
Harrogate went ahead through Mark Beck before Jason Oswell levelled for Wrexham.
Wrexham goalkeeper Kristian Dibble saved Jack Muldoon's penalty before Deverdics' winner 10 minute from time.
Harrogate travel to Fylde on Wednesday, 1 May with Wrexham at home to Eastleigh the following evening.
Wrexham or Eastleigh will face Salford City away in the play-off semi-finals on Sunday, 5 May.
Wrexham manager Bryan Hughes said: "That's four wins out of the last five and it's good form going into the play-offs.
"We won't get carried away. Eastleigh's going to be a different test again and we look forward to it.
"It's going to be a tough game. The play-offs are a lottery and I'm sure Eastleigh will be saying the same thing in their camp. We'll go into it full of confidence."
