Authentication
Workspace API keys and connecting your Buffer account.
API keys
Every workspace has keys in two environments. Prefix tells you everything:
| Parameter | Type | Description |
|---|---|---|
| bsk_live_…* | string | Acts on the live workspace connected to Buffer |
| bsk_test_…* | string | Acts on the sandbox workspace — unlimited free test posts |
| bat_… | string | OAuth access token issued by the authorization-code flow |
Keep live keys secret
Use environment variables, rotate from the dashboard if a key leaks, and prefer bsk_test_ in CI.Buffer authorization
Open Buffer account to connect. Authorize through your app's registered Buffer client or enter a personal key for your own account.
