Replace a card

Authorizations

X-API-Key
string
header
required

User API key authentication. Create a key under Settings → API keys in the Slash dashboard (https://app.slash.com/global-settings/api-keys) and send the x-legal-entity header naming the legal entity to act on with every request. Keys scoped to a legal entity are rejected with 403 user_api_key_required.

Headers

X-Idempotency-Key
string
required

Unique caller-generated key for one create request. Once an authenticated, schema-valid request reaches the operation, the key is permanently consumed for that operation and legal entity whether the operation succeeds or fails. Reusing it in that scope returns 409 and never replays a response, unlike API v1, which replays the original response for a matching key.

Required string length: 1 - 255

The legal entity to act on. Required on every request; a user API key can act on any legal entity its user has access to.

Pattern: ^le_[a-zA-Z0-9]+$
