Help Needed: Parsing JSON Inside choices[0].message.content (OpenAI API)

Hey everyone! 👋
I’m calling OpenAI’s API from FlutterFlow, and the response contains a JSON string inside choices[0].message.content.

Here’s an example of the response I’m getting:

json

{ "choices": [ { "message": { "content": "{ \"ingredients_list\": \"Grapefruit juice (100%)\", \"harmful_ingredients\": \"\", \"beneficial_ingredients\": \"Vitamin C\", \"overall_evaluation\": \"100% natural, no additives\", \"isHealthy\": true }" } } ] }

🧩 What I did:

I set up the API call in FlutterFlow.
Used $.choices[0].message.content as the JSON path.
Enabled Parse as Data Type and selected a custom ApiResponseContent data type I created with:
```
json
```
{ "ingredients_list": "string", "harmful_ingredients": "string", "beneficial_ingredients": "string", "overall_evaluation": "string", "isHealthy": true }

The issue is:
Since content is a stringified JSON, FlutterFlow is not parsing it into the defined data type — I can get the raw string but not access its internal fields like isHealthy or ingredients_list.

❓What’s the correct approach to parse and access the internal fields of a JSON string in FlutterFlow?

Should I use Set from Variable + some custom logic?
Do I need to create a Custom Function to parse the JSON manually?
Or is there another trick for this?

Any help or pointers would be super appreciated 🙏
Let me know if you’ve handled something similar. Thanks in advance!APİAPapiapi
