FAQ
Voice notification FAQ: onboarding and authentication, send results, template countries, and CDR push.
A collection of frequently asked questions about integrating and using voice notifications. For a quick lookup of error codes, see Error Codes.
Onboarding and Authentication
What credentials should requests carry?
Send the header Authorization: Bearer {API_KEY}; the API Key is created in Console > Developers. Voice APIs do not support the CheckSum signature yet. See Authentication.
How do I troubleshoot a 401 response?
Confirm in order: the request carries the Authorization header, the API Key is correct and not deleted, and the account / API Key / product authorization are all in effect. See the HTTP 401 rows in Error Codes for the matching scenarios.
Getting 403「IP 不在白名单」(IP not on the whitelist)?
The IP whitelist is mandatory: when no whitelist is configured for the API Key, all requests are rejected. Configure the egress IP whitelist for the API Key on the platform before calling; multiple whitelist entries are unioned, and changes take effect within about 60 seconds.
