payment_gateway is invalid

[jelo]

I have an unlisted sales channels app and I already have payment processing enabled. I'm using the Shopify Python API. But I can't seem to process payments. I receive the following errors:

{
  "errors": {
    "payment_gateway": [
      {
        "code": "invalid",
        "message": "is invalid",
        "options": {}
      }
    ],
    "checkout": {
      "payment_gateway": [
        {
          "code": "invalid",
          "message": "is invalid",
          "options": {}
        }
      ]
    }
  }
}

 
I'm using the Bogus Gateway.
