# Transaction Spending Limits Endpoints

## Get Transaction Spending Limit Response From Hex

<mark style="color:blue;">`GET`</mark> `/api/v0/get-transaction-spending-limit-response-from-hex/{transactionSpendingLimitHex}`

This endpoint converts a hex string representing a TransactionSpendingLimit object into a client-friendly [#transactionspendinglimitresponse](https://docs.deso.org/deso-backend/api/..#transactionspendinglimitresponse "mention") object. This is mainly used by identity to parse the transaction spending limit from extra data of an [#authorize-derived-key](https://docs.deso.org/construct-transactions/derived-keys-transaction-api#authorize-derived-key "mention") transaction to show the user the permissions they are granting to a derived key.
