What are you trying to do?

I want to start a checkout, in order to save a PaymentMethod for a Customer in Stripe. I want to use the Stripe Tax API in order to automatically generate VAT for the price. This is an example of what I need to do, everything is written in Golang.

params := tier.CheckoutParams{
		RequireBillingAddress: true,
                Features: features,
		CancelURL: "http://localhost:3000/cancel",
		Tax: tier.Taxation{
			Automatic: true,
			CollectID: false,
		},
	}

url, err := client.Checkout(ctx, "org:" + organizationId, "http://localhost:3000/checkout", &params)

However, I'm getting this error:

local-db-tier-1  | tierDEBUG: 172.28.0.4:45528 POST tier:8081 /v1/checkout: checkout: stripe: req_xAVa3TLiqBgbf2 code:customer_tax_location_invalid type:invalid_request_error message:Automatic tax calculation in Checkout requires a valid address on the Customer. Add a valid address to the Customer or set either `customer_update[address]` to 'auto' or `customer_update[shipping]` to 'auto' to save the address entered in Checkout to the Customer.
local-db-app-1   | 2023/07/12 07:55:54 stdout: Error checking out: httpError{status:500 code:"internal_error" message:"Internal Server Error"}

After some digging, I have found that this works just fine, as long as the organizationId maps to an organization with a valid adress. This is entirely reasonable, but I want to be able to update this using Tier.

How should we solve this?

In the Node SDK, there's an updateOrg function, but that doesn't exist in the Go SDK. I dug through the source for both libraries, but couldn't figure out if there was an alternative way to do what I want to accomplish.

What is the impact of not solving this?

I could solve this by using the Stripe API to update a customer, but I'm using Tier to avoid having to deal with Stripe. It feels like I'm missing something, since the address update seems to be a prerequisite to the Taxation field, that's supported by the Go SDK.

Anything else?

I think Tier is a great initiative, and could be a great product moving forward! Thanks for that!
