We connected a POST API to SendGrid within our email workflow to capture FIN's response to users and store it as audit evidence in forwarded emails. However, we haven't found any parameter or attribute that exposes FIN's response text.
Is there a way to create a custom attribute to pass this value, or do you recommend an alternative method to capture it?

If you share a little more about the specifics of your need here, then that could help narrow down the options, but an alternative would be to remove that part of the email workflow entirely, and instead subscribe to the conversation.operator.replied webhook topic ("Fin/Bot replies to a conversation" — topic list). The payload's conversation_part.body is Fin's reply text, and the author object tells you it's Fin:
Three things that will bite you on an audit trail specifically:
If you need the whole thread rather than each reply as it happens, call GET /conversations/{id} and use conversation_parts, taking parts where part_type is comment. Two tips for audit evidence: pass display_as=plaintext so you get clean text instead of HTML for the forwarded email, and note the API returns a maximum of 500 parts (the most recent 500 on longer conversations).
For audit purposes I'd also store conversation_part.id and created_at alongside the body (the ID gives you deduplication and the timestamp gives you ordering). ai_agent.resolution_state and content_sources are worth capturing too: they evidence what Fin based the answer on, which could be a question an auditor actually asks.
