}Authorizations
Your API key (ta_live_…) from Settings → API keys, sent as Authorization: Bearer <key>. Keep it on a server: it can message every customer you have. A key is full, build or read-only; a request its level does not allow is refused with 403.
Headers
Developers only: the customer workspace this request acts in — its org_… id from POST /customers. Leave it out to act in your own workspace.
