# Delete an enrolled SCA factor

`DELETE /sca/factors/{credentialId}`

## Request

- Base URL: `https://api.lightspark.com/grid/2025-10-13`
- URL: `https://api.lightspark.com/grid/2025-10-13/sca/factors/{credentialId}`
- Auth: HTTP basic

Delete an enrolled SCA factor by its credential id. Today only `PASSKEY`
factors carry a `credentialId` and are deletable this way.

This endpoint is only meaningful for customers in a region where SCA is required (e.g. EU). For customers outside SCA-regulated regions, this returns `409`.

## Response `204`

Factor deleted; no content is returned.

## Other responses

- `400`: The authentication provider rejected the request as caller input, for example a malformed factor or reset reference.
- `401`: Unauthorized
- `404`: Customer or factor not found
- `409`: SCA is not required for this customer.
- `500`: Internal service error
