# Resend a quote's SCA challenge code

`POST /quotes/{quoteId}/authorize/resend`

## Request

- Base URL: `https://api.lightspark.com/grid/2025-10-13`
- URL: `https://api.lightspark.com/grid/2025-10-13/quotes/{quoteId}/authorize/resend`
- Auth: HTTP basic

Re-send the one-time code for a realtime-funding quote in
`PENDING_AUTHORIZATION` status whose `scaChallenge.factor` is `SMS_OTP`. The
existing challenge is reused — no new challenge is issued, and its
`scaChallenge.expiresAt` is **not** extended; once the challenge is past
`expiresAt` it can no longer be authorized.

Only meaningful for customers in a region where SCA is required (e.g. EU);
a 409 is returned otherwise. `PASSKEY` challenges cannot be re-sent and return 409.

In sandbox, the code is always `000000`.

## Response `204`

Code re-sent.

## Other responses

- `401`: Unauthorized
- `404`: Quote not found
- `409`: SCA is not required for this customer, the quote has no pending SMS challenge, or the challenge uses a factor whose code cannot be re-sent (e.g. passkey).
- `429`: Too many requests. Returned with `RATE_LIMITED` when codes are re-sent too frequently, to avoid spamming the customer's phone. Clients should back off and retry after the interval indicated by the `Retry-After` response header.
- `500`: Internal service error
