You are making a webhook POST request, this would send data not receive it. This hook would be better implemented inside HYROS but I have a feeling that there would not be a triggering event to fire it. Do see their documentation.  

Webhooks are typically used to send data to a specified URL, where it is caught and processed by the receiving system. In your case, you wish to make an API call, which involves sending a request to an endpoint and receiving data back as a response

Zapier does not appear to have an API request action set-up for HYROS. This may mean you will need to code one to ensure authorisation is correctly handled. AI should be able to help with this. I personally would use python as I find it easier to understand and ChatGPT is very helpful and with trial and error you can achieve significant results. 

Do read their API documentation here https://hyros.docs.apiary.io/# and webhook documentation https://docs.hyros.com/hyros-webhooks/

An example API CALL code block

import requests

# HYROS API configuration
API_KEY = 'your_api_key_here'  # Replace with your HYROS API key
ENDPOINT_URL = 'https://api.hyros.com/v1/attribution'  # Replace with the HYROS endpoint you need

# Define headers for the API request
headers = {
    'Authorization': f'Bearer {API_KEY}',
    'Content-Type': 'application/json',
}

# Define parameters for the API request (modify as needed)
params = {
    'start_date': '2023-01-01',  # Example parameter
    'end_date': '2023-12-31',    # Example parameter
}

try:
    # Make the GET request to the HYROS API
    response = requests.get(ENDPOINT_URL, headers=headers, params=params)

    # Check if the request was successful
    if response.status_code == 200:
        data = response.json()  # Parse JSON response
        # Use the data as needed
        return {'status': 'success', 'data': data}
    else:
        # Handle API errors
        return {
            'status': 'error',
            'code': response.status_code,
            'message': response.text
        }
except Exception as e:
    # Handle other errors (e.g., network issues)
    return {
        'status': 'error',
        'message': str(e)
    }

Hope this helps.
 

I appreciate this. It does makes sense now. I'll definitely try this and let you know how it goes. Thanks!
