Here’s a clear explanation of “Xiaomi BD Auth Tool Credits for Existing User (API)” — what it is and how it typically works for existing users:
Xiaomi BD Auth Tool is a third-party service/tool used mainly by mobile repair technicians to perform advanced operations on Xiaomi devices such as:
Account authorization / Mi account issues
FRP (Factory Reset Protection) removal
Bootloader unlock
Flash and EDL mode operations
EFS reset and other deep service functions
This tool usually works via credits, which customers purchase and then consume per operation. The “API” in many listings means the seller provides automated credit delivery via an API, so credits are added to your account quickly after payment.
When the listing says “Credits for Existing User (API)”, it generally means:
You need an existing BD Auth Tool account (registered with a username/email).
Credits are added to your existing account rather than creating a new one
After purchase, credits are automatically delivered to your account using the seller’s API system.
Delivery is usually fast (often within minutes, depending on service).
Credits are consumed when you perform a specific operation in the Tool, for example:
Removing FRP lock
Flashing firmware
Authorizing a Mi account
Each action costs a certain number of credits depending on the operation and device model
Prices vary by reseller and region but typically are quoted per credit unit. For example, some listings show around $0.3–$0.8 per unit for Xiaomi BD Auth Tool credits for existing accounts
⚠️ Exact steps may vary by service provider. This is a common pattern used by repair service resellers.
Step 1: Create / Have an Account
Register on the Xiaomi BD Auth Tool provider site if you don’t already have an account.
Step 2: Purchase Credits

Step 3: Provide Your Username/Email
When placing the order, give the same username/email of your BD Auth Tool account.
Step 4: Receive Credits Automatically
Credits are added to your account via API once the payment is confirmed.
Step 5: Use Credits in the Tool
Log into the tool with your account and perform the service you need — credits will be deducted accordingly.
