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.
