Best Practices
Credential Management
It is recommended to create separate captcha_id and captcha_key for different business scenarios and platforms to facilitate data analysis and strategy adjustment. Test environments can share a set of credentials.
JavaScript Loading
The following files have low update frequency and can be downloaded to your local CDN:
gl4.js- Initialization scriptbypass.js- Fallback handling script
Other resources are recommended to be loaded from Geelab CDN to get the latest updates.
Disaster Recovery
The client SDK has built-in disaster recovery logic. The server needs to handle exceptions from the verification API:
When the HTTP status code is not 200, it is recommended to allow the request through. You can implement a verification switch as an additional fallback solution.
Verification Type Selection
Trade-offs between security and user experience for different verification types:
| Verification Type | Security | User Experience | Use Case |
|---|---|---|---|
| One-Click Pass | Low | Best | Low-risk scenarios |
| Slide Puzzle | Medium | Good | General scenarios |
| Match Game, Gomoku | Medium | Good | General scenarios |
| Icon Click, Nine-Grid | High | Lower | High-risk scenarios |
Dynamically adjust verification types based on actual risk conditions.
