🔍 Frequently Asked Questions

Q: How to generate random string?

A: You can use the following methods:

  • JavaScript: Use crypto.randomUUID() or custom function
  • Java: Use UUID.randomUUID().toString().replace("-", "")
Q: How to handle nested objects?

A: Use recursive function to flatten nested objects, use dot notation to separate hierarchy.

Q: How to represent array parameters?

A: Array parameters use square bracket indices, e.g., items[0].price=100&items[1].price=200

Q: What to do if signature verification fails?

A: Please check:

  1. Is parameter sorting correct?
  2. Is timestamp within validity period?
  3. Is nonce being reused?
  4. Is API Secret correct?
Q: Which programming languages are supported?

A: We provide complete examples for JavaScript and Java. Other languages can refer to the signature algorithm for implementation.
