Steps
Authenticate with an Authorization: Basic base64(identifier:key) header using either a website token or a plugin token keypair
If using a plugin token, also send the X-Crisp-Tier: plugin header alongside Basic auth
Create a conversation with POST /v1/website/{website_id}/conversation
Send a message with POST /v1/website/{website_id}/conversation/{session_id}/message, choosing a type such as text, note, file, or carousel — the call returns 202 Accepted since delivery is asynchronous
Read or change conversation state with GET or PATCH /v1/website/{website_id}/conversation/{session_id}/state, using values pending, unresolved, or resolved
Known gotchas
Conversations are addressed by session_id, not a numeric conversation ID
Website tokens and plugin tokens have different scopes; mismatching the X-Crisp-Tier header with the token type causes 403s
Sending a message returns 202 (accepted, async) rather than 200, and error responses can include 402 Payment Required for plan/quota gating
