Every new or modified skin should be approved by the APS team to avoid breaking the backward compatibility with the future platform releases. Approved skins are tested by the APS team with every platform version to ensure stable work. Before you deliver a new or modified skin to customers, pack the skin files in the ZIP archive and submit it to the APS catalog for validation.
You need to register in the APS development portal and then upload the skin file there for validation as follows:
The APS catalog team will review the uploaded skin package and then mark it as approved or rejected. Once the custom skin is approved, you will get a notification email from the APS catalog team. If there are any issues preventing the skin from being approved, the APS team will help you fix them.
