Modify a Card
Updates the details of an existing Card, including adding new Spend Controls after the original Spend Controls expire.
Authentication
OAuth 2.0 client credentials. Exchange your API key and secret for a bearer token, then send it as Authorization: Bearer <token>.
Path parameters
Request
The Spend Control object determines how, when, and where on-demand cards can be authorized. The cards in INACTIVE status do not have an existing Spend Control object. So, if OPTIONAL fields are unpopulated in a PUT /cards call for an INACTIVE Card, their value will be defaulted to those defined during the initial configuration set up.
This object is for the details of the user who is logged into your app when the request for modifying an on-demand Card is made. This information will support customer service and fraud mitigation by American Express.
