That 400 "Body payload validation error" is usually a JSON formatting issue. Can you copy and paste the exact JSON from your request body into the chat? That'll help me spot what's wrong.
Common fixes for this error:
Put quotes around string variables: {"name": "/Name Column"} not {"name": /Name Column}
Check commas between fields: {"name": "John", "age": 30}
Remove any hidden characters by pasting into a plain text editor first
Also try using Sculptor (top-right corner) - describe what you want to do with Attio and it can generate the proper API configuration for you. [1] [2]

Found the issue! You have trailing commas and empty string values that are causing the validation error.
Problems:
1.
Trailing comma after the last field "status_page_score": " " }
2.
All your values are empty strings " " - Attio likely requires actual data
Quick fixes:
1.
Remove the comma after "status_page_score": " "
2.
Replace empty " " values with actual column references like "/Domain Column" or remove optional fields entirely
Clean version:
{ "domains": "/Domain vF", "name": "/Name vF" }
Start with just the required fields (domains + name) first, then add optional ones once it works. [1]

Ah gotcha! Instead of copying field values, you need to reference your Clay columns properly in the JSON.
Replace those empty strings with column references like:
{ "domains": "/Domain vF", "name": "/Name vF", "description": "/Description vF" }
The /Column Name format tells Clay to pull data from that specific column. Remove any fields you're not using to keep it clean. [1] [2]
Also remove that trailing comma after the last field - JSON doesn't allow those.

Found the issue! There's an extra space in your funding_raised_usd field:
"funding_raised_usd": " " + Clay.formatForJSON(#{{Fundraised $ vF}}) + "\"
Should be:
"funding_raised_usd": "" + Clay.formatForJSON(#{{Fundraised $ vF}}) + "\""
That extra space before the first quote is causing the validation error. Also, since you're using Clay.formatForJSON(), you don't need the extra quotes around each field - that function handles the JSON formatting automatically. [1]
Try this cleaner version:
{ "domains": Clay.formatForJSON(#{{Domain vF}}), "name": Clay.formatForJSON(#{{Name vF}}), "funding_raised_usd": Clay.formatForJSON(#{{Fundraised $ vF}}) }
The Clay.formatForJSON() function already handles proper quoting and escaping.
