Verify Signature Result

To improve service security, Tuya has updated the signature algorithm. This topic describes how to view the input parameters and decryption result of sign by using Postman. You can verify the encryption result of sign in the cloud API requests.

Prerequisites

• You have downloaded the Tuya API package.
• You have installed Postman and can make API requests by using the Tuya API package. For more information, see Set Postman Environment and Call API Operations.

Procedure

The API package provides scripts for calculating sign. You can use Postman’s console to print log parameters for verification.

1. Add code to print console.log.
   In Postman, log in to the Pre-request Script page and find function calcSign. In the function, add the following code lines:

   // `str` is the input parameter of encryption
   console.log("str:",str);
   // `sign` indicates the encryption result
   console.log("sign:",signUp)
   

   Note: The verification calculation parameters of token requests (the APIs to get and refresh a token) are different from that of business requests (APIs other than the token management APIs). Select the correct API request calculation rule.

   

2. Log in to the Console.

   

3. Call APIs and view the returned result.
