# Checkpoint providers

Connect your own Linkvertise, LootLabs, Work.ink, or LinkUnlocker account. Users complete your links; the provider pays your account directly.

A usable provider needs a credential, at least one link, a return/callback anchor, a valid package, and its enabled switch on. A saved token alone does not make a provider available.

Open the project’s Checkpoints tab, connect the provider, add links and packages, save, then test the public key page. Each provider guide explains the return-path details.

The active flow uses one provider per package. Mixed YouTube/ad packages are not part of this documented release.
