Subject: Issue with Interakt API Integration – Getting 500/404 Errors
Message:
Hello Pabbly Support Team,
I am trying to send WhatsApp messages using Interakt API via Pabbly Connect, but I'm consistently receiving error responses like:

• 500 - The application processed the request but returned a blank response, or
• 404 - Not Found

? Here is my setup:

• App: Custom API by Pabbly
• Method: POST
• Endpoint: https://api.interakt.ai/v1/public/message
• Authentication: Bearer Token (Token verified & never expires)
• Content-Type Header: application/json
• JSON Body:

{
"receiver": "919426334349",
"message_type": "text",
"message": {
"type": "text",
"text": "✅ MyZone Auto Reply working! How can I help you?"
}
}

• I’ve verified this works from Postman, but in Pabbly it returns either 500 or 404 depending on the configuration.

✅ I’ve already confirmed with Interakt support that the API key, number and endpoint are all active and correct.
Kindly check from your end if this is a configuration issue in Pabbly or if some setup adjustment is required.
Looking forward to your help.
