Troubleshooting steps
First, check your signature algorithm. Refer to our Server SDK for different language versions.
Next, verify the parameters used to calculate the data signature (Signature). Parameter error is a common cause of this issue.
How to calculate the data signature (Signature)
Concatenate the following three strings in order (App Secret + Nonce + Timestamp) and perform an SHA1 hash calculation.
- App Secret: Log in to the RC Developer Console to retrieve the App Secret corresponding to the App Key of your app.
- Nonce: Random number
- Timestamp: Timestamp
A common mistake is using the App Key instead of the App Secret mentioned above during the SHA1 calculation.
