Stripe subscription creation failed - parameter_unknown: source

Question

I have created a function in firebase to create a stripe subscription on the creation of a user. This was all working great however when I switched to another stripe account (switched api keys for front and backend and changed plan_id)

I am getting the following error: Received unknown parameter: source.

I have one stripe account where the code works and another account that handles the code differently. I can switch api keys and watch it go from failing to succeeding and vice versa.

This is the part of my code that creates the subscription

return stripe.subscriptions.create({
      customer: customerId,
      source: collectedToken,
      coupon: couponId,
      items: [{plan: 'plan_xxxxxxxx'}],
});

Checked all API keys are correct for backend and frontend for the stripe account. Frontend during testing was exactly the same except for using different stripe api keys. I tried Switching firebase accounts to see if that was the issue but got the same result.

What is working is creating a customer and token which matches the data being logged on that stripe account but it all fails when creating a subscription. This made me think that it was a config error in my stripe account. I have gone through both stripe accounts making them as identical as possible.

  "billing": "charge_automatically",
  "billing_cycle_anchor": 1549977641,
  "billing_thresholds": null,

.................

I would expect if the plan, customer, token were valid it should work on another stripe account if that stripe account was set up the same way.

It's probably due to the fact that the new API Key you're using is running on a newer version of the Stripe API. You can check the version(s) under your developers section of the dashboard.

In the updated subscriptions API you only need a customer and a plan (within a list of items) in order to create a new subscription. Source was removed completely and the API now is relying on the default source for the customer.
