Help with Accessing Nested JSON Data in API Response

Hello Voiceflow Community,

I'm working on integrating an external API with my Voiceflow project and need help with parsing a nested JSON response to extract specific data and store it in Voiceflow variables.

Here is the structure of the JSON response I'm dealing with:

[
{
"recipient_id": "507f1f77bcf86cd7990421",
"custom": {
"user_id": "507f1f77bcf86cd799489321",
"question": {
"message": "What food do you have that is gluten free?"
},
"summary": "Detailed summary here...",
"products_detail": [
{
"name": "Product Name",
"seo_description": "Description here...",
"background": null,
"type": "Product Type",
"feelings": {
"Relaxed": 0,
"Sleepy": 0
},
"helps_with": {
"Weight": 0,
"Digestion": 0
}
}
]
}
}
]

What I need:

1. How to correctly use the JSON path notation in Voiceflow to access the name within products_detail.
2. How to store this value into a Voiceflow variable for further use in the conversation.
What I've tried:

I've attempted using paths like response[0].custom.products_detail[0].name, but it doesn't seem to work.
My API call setup is correct, and it works in Postman with the same endpoint and parameters.
Any insights or examples of how you handle similar JSON parsing in Voiceflow would be incredibly helpful!

Thank you!
