Authentication

After creating your merchant account, LedgerBlock verifies the merchant information before the account can be used for API transactions.

Once the merchant has been verified and the x_merchant_ref has been approved, it can be used to authenticate requests to the LedgerBlock API.

Why Authentication Is Required

Authentication ensures that API requests are associated with a verified LedgerBlock merchant.

It enables the merchant to:

• Identify and authorize API requests.
• Access LedgerBlock services securely.
• Create and manage users under the merchant account.
• Associate API activity with the correct merchant account.
• Prevent unauthorized access to merchant resources and transactions.

The x_merchant_ref and API key are generated during merchant onboarding and should be stored securely. The x_merchant_ref can only be used after LedgerBlock has completed the merchant verification and approval process.
