Auto-scan Stores
Individual store links will automatically populate for all supported Auto-scan Stores once the Pre-Save Link converts to a Released Music Link. These store links are not necessary in order to collect pre-saves!
Once your link converts, the Feature.fm auto-scan function begins matching the source code (Scan Source) across DSPs to pull in and populate the store-specific URL. As long as the Auto-scan button is switched on for the DSP, and your music is available on that platform, the store link should automatically populate after the link converts.
For a list of supported Auto-scan Stores, refer to this article: Supported Scan & Automatch Stores
Custom Stores and Non Auto-scan Stores
For any custom stores or DSPs not supported with auto-matching, links will need to be added manually in order for these stores to display on the landing page.
My Pre-Save Link converted, and there are store links still missing
In this case, you can manually re-trigger the auto-scan by clicking Scan next to the source code. If your music is retrievable, the store links should populate.
For best matching results, it is recommended to use a UPC or ISRC. Using a URL from another DSP may not match across all DSPs.
