# Allow

`POST /defi/v1/lendborrow/allow`

## Request

- Base URL: `https://svc.blockdaemon.com`
- URL: `https://svc.blockdaemon.com/defi/v1/lendborrow/allow`
- Auth: API key in header `X-API-Key`

Grants or revokes permission for designated manager addresses to operate on your account. You specify a manager's address along with a flag indicating whether they're allowed or disallowed, and the transaction is executed with customizable gas settings.

> 💡 
**Compute Unit Value:** `115` (Fixed)

## Request body

- LendborrowAllowRequest: The request body for a /defi/v1/lendborrow/allow
  - `lendborrowId` '1300' | '1302': The unique ID to specify the lending and borrowing protocol for routing relevant queries or transactions.
  - `manager` string, required: The address of the account that will be granted or revoked manager permissions.
  - `isAllowed` boolean, required: Set to 'true' to allow the manager or 'false' to disallow the manager. Defaults to 'true'.
  - `from` string, required: Blockchain address of the sender. For EVM chains, use a checksummed hex address (e.g., 0xABCDEF...). This address must hold sufficient balance and will sign the transaction.
  - `gas` string: Maximum number of gas units to allocate for the transaction, as an integer string (e.g., '200000'). If omitted, gas is estimated automatically. Note: this is gas units, not wei or gwei.
  - `gasPriority` string: Specifies the priority level for gas fees (e.g., 'low', 'medium', or 'high'), which influences the transaction speed and cost.
  - `market` string: Standard market choice like USDC or WETH. Defaults to USDC if not specified.
  - `enableFee` boolean: Flag to include a basis points fee transaction alongside the main transaction when set to true.
  - `simulate` boolean: When true, dry-runs the transaction batch via eth_simulateV1 and returns a simulate field with status and error on each transaction.
