V2 Queued Response: All API requests in V2 are queued for improved reliability. You’ll receive an immediate response with a queued_request_uuid that you can use to check the actual message status.

​
Response Format

All requests return a queued response: 
{
    "queued": true,
    "message": "Processing your request...",
    "queued_request_uuid": "a0816120-7e37-4e8b-8cf3-92deb2cdc133",
    "queued_request_link": "https://app.hypersender.com/api/whatsapp/v2/{instance}/queued-requests/a0816120-7e37-4e8b-8cf3-92deb2cdc133"
}
Use the queued_request_link or the Get Queued Request endpoint to check the actual message response once it’s processed. More details on queued requests can be found in the Queued Requests Documentation.
Send links and simple texts to a WhatsApp
  • Chat
  • Group
  • Recipient
We highly recommend using the send-text-safe endpoint for regular messaging operations to maintain a more natural communication pattern, and keep your whatsapp number safe from being blocked.
If the text has a link - it generates a preview for that link. You can adjust the behaviour by setting
  • link_preview: true - to enable link preview
  • link_preview_high_quality: true - to enable high-quality link preview
send-text send link preview
