Use campaign.next_action to follow the workflow. Publication is confirmed only by campaign.display_active=true. No MPP, Shared Payment Token, or headless recurring payment endpoint is currently offered. Initial payment uses hosted Stripe Checkout with owner authorization; renewals then run automatically.

Submit multipart artwork for approval, store the returned private campaign token, then obtain Stripe Checkout after approval. Approval alone does not reserve inventory. Recurring charges require the payer's explicit authorization; card authentication can require human interaction. Never send a management token to any other origin. Cancel renewal via the API or Stripe portal and retain the already-paid period. See the guide for complete terms and examples.
