Hey @Poseidon, there can be some nuance in how these app types get classified, however based on what you have shared, your app sends product data to marketplaces you don’t own, which puts it under requirement 1.1.6 as it’s applied today. The Sales Channel path exists for marketplace integrations, but it currently requires the developer to own the destination platform.
The underlying use case for helping merchants in a growing market connect to the platforms they already rely on is useful. I’ll pass that context along with a feature request on your behalf.
