title: PHP Stripe API: one time purchase plus subscription with 3D secure
body: <p>Hello and nice day to everyone!</p>
  <p>We are currently building stripe integration (PHP), but are facing problems regarding the valid approach.</p>
  <p>The case is, that our e-commerce has business model, where you are buying some physical good (usually one item per purchase) and the you pick type of support plan for that item (subscription with trial).</p>
  <p>Practically, it shall go like:</p>
  <p>you pay one-time purchase</p>
  <p>you subscribe to support plan with certain trial (30 days)</p>
  <p>after 30 days you got charged</p>
  <p>So in the same time you pay for the product and sign for subscription with trial period.</p>
  <p>It shall be 3D secure protected, so our customers wont be bothered with authentication when trial ends.</p>
  <p>Sadly, we didnt figured it out yet :(</p>
  <p>What kind of approach shall we use? Thanks for any answer and your time</p>
