How this service works
Disposable email inboxes for agents — create, receive, read, and send. Pay per call.
Output
Returns the updated inbox object including the slug, the new webhook URL, display name, and — if the webhook URL was newly set or changed — a one-time webhook_secret string for HMAC signature verification that must be saved immediately.
Example use cases
Example prompt
“Update my PayWeave Mail inbox 'agent-007' to forward incoming emails to https://myserver.example.com/hooks/mail, and set its display name to 'Agent Inbox'.”
Technical details
Endpoint
POSThttps://mail.payweave.services/inboxes/%7Bslug%7D/updateWhen to prefer
Use this endpoint when you need to attach or change a webhook notification URL on an already-created disposable inbox, or when you want to set a human-readable display name for an existing inbox. Choose this over inbox creation if the inbox already exists and you only need to reconfigure its settings.
Side effects
- Inbox slug not found — 404 if the slug does not correspond to an existing inbox
- Invalid webhook URL format — 400 if webhook_url is not a valid URI
- Payment required — 402 if x402 payment header is missing or insufficient
- Webhook secret only returned once — if caller doesn't capture it at response time, it cannot be retrieved again
- Empty body — if neither field is provided, update may be a no-op or return 400
