Quickstart

1. Get an RCS number. Ask your account manager to assign one to your account. It appears in GET /v3/phone_numbers.

2. Subscribe to webhooks with POST /v3/webhook-subscriptions, so replies (message.received) and delivery status (message.delivered, message.read) reach you.

3. Start a chat with POST /v3/chats, using your RCS number as from:

   curl https://api.linqapp.com/api/partner/v3/chats \
     -H "Authorization: Bearer $LINQ_API_KEY" \
     -H "Content-Type: application/json" \
     -d '{
       "from": "+12025550100",
       "to": ["+12025550123"],
       "message": { "parts": [{ "type": "text", "value": "Hello from Linq" }] }
     }'

   The first message of a new chat cannot contain a link.

4. Keep the conversation going with POST /v3/chats/{chatId}/messages, using the chat_id from step 3.

See the API reference for every operation available on an RCS number.
