title: For how long is a Stripe card token valid?
body: <p>For approximately how long is a Stripe card token (aquired through Stripe.js) valid? <a href="https://stripe.com/docs/custom-form#next-up" rel="noreferrer">According to the docs</a>:</p>
  
  <blockquote>
    <p>The token is single-use only and has a short life. Use it in an API
    call immediately.</p>
  </blockquote>
  
  <p>I understand I shouldn't store the token for use later, but how short is "short" in this case? Should I expect it to expire within seconds or minutes?</p>
  
  <p>(Although not relevant to the question itself, the reason I'm asking is that I would like to take the token exchange step out of the transaction that the user is waiting for, and let a background job handle the actual Stripe integration. Obviously, that's not a good idea if the token has a <em>very</em> short lifetime.)</p>
