b2_list_keys

Lists application keys associated with an account.

Request

Request HTTP Headers

Authorization

required

An authorization token, obtained from b2_authorize_account. The token must have the listKeys capability.

Request HTTP Message Body Parameters

accountId

required

The ID of your account.

maxKeyCount

optional

The maximum number of keys to return in the response. Default is 100, maximum is 10000.
NOTE: b2_list_keys is a Class C transaction (see Pricing). The maximum number of keys returned per transaction is 1000. If you set maxKeyCount to more than 1000 and more than 1000 are returned, the call will be billed as multiple transactions, as if you had made requests in a loop asking for 1000 at a time. For example: if you set maxKeyCount to 10000 and 3123 keys are returned, you will be billed for 4 Class C transactions.

startApplicationKeyId

optional

The first key to return. Used when a query hits the maxKeyCount, and you want to get more. Set to the value returned as the nextApplicationKeyId in the previous query.
