Rails - Stripe::InvalidRequestError (Must provide source or customer.)

As mentioned in the docs, stripe expects either customer or source to be mentioned while creating a charge. So, you either need to

• Create a customer on stripe(if you want to charge that customer in future too) from the token you received, and mention that customer while creating a charge,

  customer = Stripe::Customer.create(source: params[:stripeToken])
  
  charge = Stripe::Charge.create({
    :amount => 400,
    :currency => "usd",
    :customer => customer.id,
    :description => "Charge for [email protected]"
  })
  

• Or, if you don't want to create a customer, then directly mention received token as a source,

  Stripe::Charge.create({
    :amount => 400,
    :currency => "usd",
    :source => params[:stripeToken],
    :description => "Charge for [email protected]"
  })
