Start adding a card in Stripe Checkout

POST
/v1/public/payment-updates/{token}/checkout
curl --request POST \
--url http://localhost:8080/v1/public/payment-updates/example/checkout

Returns a Stripe Checkout URL in setup mode (card only, no charge). Creates the Stripe customer if there is none. This call uses up the token. If Stripe fails to create the session, the token works again. Stripe sends the customer to the payment-method-added page with ?status=success or ?status=cancel. Writes an audit row.

token
required
string

Checkout session created.

Media typeapplication/json
object
url
required

Stripe Checkout URL.

string

Example generated

{
"url": "example"
}

The token is unknown, expired or already used. Code invalid_token.

Media typeapplication/json
object
error
object
type

One of invalid_request_error, authentication_error, rate_limit_error or api_error. Every error the API answers has this shape, including an unknown path (404, code route_not_found) and a method the path does not take (405, code method_not_allowed, with an Allow header). The few exceptions are listed in docs/api-surface.md.

string
code
string
message
string
request_id
string
param

The request field the error is about. Sent only when the error names one. A request body may hold only the fields its operation lists, spelled and cased as listed: any other field, or one the server sets (such as id), is refused with 422 and param naming it. An operation with no request body lists no fields: send no body, {} or null. The Stripe and Postmark webhooks and the LiteLLM callback take their sender’s body as it comes.

string

Example

{
"error": {
"type": "invalid_request_error"
}
}

The seller has not connected Stripe for this mode, so a card cannot be added online. Code online_payment_unavailable. The token still works.
