Contact
No ticket maze and no generic contact form. Tell us what happened, include any useful request IDs, and we will help you find the next step.
We usually respond within two business days.
Good reasons to write
Email verification, login trouble, account access or security settings.
Subscription questions, credit packs, payment receipts or unexpected usage.
API keys, request errors, compatibility questions or production integration.
Responsible vulnerability reports, suspicious activity or account protection.
Bug reports, feature requests and ideas that would improve GLM 5.3 Online.
For an API problem, include the approximate time, endpoint, HTTP status and provider request ID when available. Remove the API key, authorization header, passwords and private prompt data before sending. A minimal request example is more useful than a screenshot of a complete secret-filled environment file.
For billing or credits, include the account email, purchase date and Stripe receipt or checkout reference. For a security report, describe the affected route, expected boundary and safe reproduction steps. Do not access another user’s data or continue testing after demonstrating the issue.
Before you email
Support will never ask for your password, complete API key or complete payment-card number. If a key may have been exposed, revoke it from the API-key page and generate a replacement before contacting us. Screenshots should hide personal data belonging to other people.
We can explain this service, investigate account records and help trace requests made through GLM 5.3 Online. Questions about a separate Z.ai subscription, upstream Coding Plan account or third-party provider must be handled by that provider. This site is independent and is not affiliated with Z.ai.
When reporting a reproducible defect, tell us what you expected, what occurred and whether it happens in a fresh session. Include the browser or SDK version when relevant. We prioritize account access, payment, security and widespread availability issues, then handle integration questions and product feedback. Email is the official support channel shown on this page; we do not provide support through unsolicited social-media direct messages. Keep the original browser tab or request log available until the issue is resolved, especially for sign-in redirects and interrupted checkout sessions.
