Endpoint: PATCH /managed_cards/{id}/spend_rules

## Path parameters:

  - `id` (string, required)

## Header parameters:

  - `idempotency-ref` (string)
    A unique call reference generated by the caller that, taking into consideration the payload as well as the operation itself, helps avoid duplicate operations. Idempotency reference uniqueness is maintained for at least 24 hours.

## Request fields (application/json):

  - `updateSpendLimitMethod` (string)
    The spend limit update method to apply. Currently supported:
- OVERWRITE: (default option if nothing selected). Overwrites the previous values for the spendLimit object i.e. sets new limits
- INCREMENT : This will increase the existing value of the spend limit by the amount input the value field. If used in conjunction with an ALWAYS interval, this can be used to increment a spend limit on a periodic basis (controlled by you, e.g. monthly), and means that any 'unused' balance from the previous period will still available to spend. See examples in our documentation
