Follow the following 3 steps

1. Joining the following parts according to string s=a+b+c+d

a. URL PATH: such as /openapi/1/123456/1688.product.search.keyword
Note that 123456 is appKey
b. Header data: x-depal-timestamp such as 1745570329174
c. Header data: x-depal-access-token such as f1 - 4 da 3b8-b0b1 -4f73-a5de-9bed637e0188
d. post body: such as {"productId":11111,"language":"en"}

2. Sign the spliced string

sign = uppercase (hex (hmac_sha1 (s, appSecret))
For example, 33E54F4F7B989E3E0E912D3FBD2F1A03 CA7 CCE88
wherein

appSecret is the value assigned by the system when applying for admission

hmac_sha1 is the general hmac_sha1 algorithm

hex is converted to hexadecimal

uppercase is converted to upper case characters

3. Put the signature string into the header x-depal-signature commit

x-depal-signature=33E54F4F7B989E3E0E912D3FBD2F1A03CA7CCE88
