On 30 June 2019, he was chosen in the Saudi program to develop football talents established by General Sports Authority.

However, with the 2020 AFC U-19 Championship cancelled due to COVID-19 pandemic, he was able to redeem himself in the 2022 AFC U-23 Asian Cup with a spectacular performance, guiding the team to conquer the first title without conceding a single goal and a near perfect record with only Japan managed to hold Saudi Arabia a draw.

Al-Aqidi once again impressed in the tournament without conceding a single goal in the group stage until the semi-finals, when he finally conceded a goal after eight consecutive clean sheets, in Saudi Arabia's 2–1 win over Algeria, albeit it was from a penalty rather than an open play.

In the final, Al-Aqidi finally conceded the first ever open play goal after nine games, which was against the hosts Turkey in a pressuring attempt that saw Metehan Altunbaş netted, yet that goal proved disastrous as Saudi Arabia proved unable to break the Turkish defence as Saudi Arabia's hope to win the second major tournament in the same year crashed by this 0–1 loss.

On 18 November 2021, Al-Aqidi called up to the senior side for the first time to take part in the 2021 FIFA Arab Cup.
