The API Gateway signature tool is a web tool provided by Tencent Cloud API Gateway to generate request signatures for key pair authentication APIs. You can set parameters on the signature tool page in the API Gateway console to generate a request signature.
2. In the left sidebar, click Tool > Signature Tool to go to the signature tool page.
3. In the Basic info module, click Obtain. The system will automatically fill in the start time and end time of the signature validity period.
4. Enter any value as the signature watermark value.
Step 2. Enter an API key pair
In the Secret key module, set the API key pair information using either of the following methods:
Method 1: click Select to select a key pair that has been created under your account.
Method 2: enter a key pair.
Make sure you enter the correct information. If the information is incorrect, your signature will be invalid.
Step 3. Generate a signature
Click Generate signature. The request signature result will be displayed in the module on the right. The main parameters are as follows:
Source: signature watermark value.
X-Date: HTTP request construction time in GMT format. The difference between X-Date and the current time cannot exceed 15 minutes.
Authorization: signing information.
Step 4. Initiate a call in Postman
Open Postman, enter the Source, X-Date, and Authorization parameters in Headers, enter the API request address, API request parameters, and other information, and click Send to call the key pair authentication API.
Note
Because the server will verify the time, you must initiate a call within the validity period of the signature. Otherwise, the call will fail.
The signature tool only verifies the validity of the parameters, but does not identify or inform you of the specific incorrect parameters.
