Authentication - Thrad Docs

The Server-to-server Conversions API requires a partner API key, sent as a bearer token:

Authorization: Bearer <YOUR_API_KEY>

Getting a key

Reach out to your Thrad contact to issue an API key for your partner / advertiser account. Keep keys server-side only — never embed them in browser code or mobile binaries.

Errors

Status	Reason
`401 Missing bearer token`	No `Authorization` header.
`401 Invalid API key`	Token doesn’t match any active key.
