WhatsApp Use uses small, endpoint-specific pagination controls.

​
Sync cursor

GET /v1/whatsapp/sync returns changed conversations, contacts, and messages.
cURL
curl -H "Authorization: Bearer $WHATSAPP_USE_API_KEY" \
  "$WHATSAPP_USE_BASE_URL/v1/whatsapp/sync?cursor=0&limit=50"
Store the returned cursor. Send it on the next sync request.

​
Message pages

Conversation messages use an optional anchor:
cURL
curl -H "Authorization: Bearer $WHATSAPP_USE_API_KEY" \
  "$WHATSAPP_USE_BASE_URL/v1/whatsapp/conversations/conv_123/messages?before_message_id=msg_123&limit=50"
Use before_message_id to page backward through a conversation.

​
Delivery and usage lists

Webhook deliveries and usage endpoints accept limit. If omitted, the API chooses a default page size.
