title: Difference between Omnipay and Payum
body: <p>I was looking for a payment solution for my web-app. I saw that there are APIs like stripe (for credit cards) or PayPal plugins that can deal with certain paying methods. </p>
  
  <p>Then I saw that there are libaries that can deal with all sorts of paying methods like Payum (<a href="https://github.com/Payum/Payum">https://github.com/Payum/Payum</a>) or Omnipay (<a href="https://github.com/thephpleague/omnipay">https://github.com/thephpleague/omnipay</a>).</p>
  
  <p>If I understood it correctly they are both the same type of library: They both process payments of various methods in a standardised way. However I did'nt find any comparison between the two, but solutions to how Payum can include OmniPay. So I got confused. Thus my question:</p>
  
  <p>Does Omnipay cover the same purposes as Payum. If yes, which one has what advantages. If no, what parts of the paying process are they exactly implementing.  </p>
