Hi @Kylepressley,
Welcome to the community
I guess the issue that you didn’t got a response from the custom action because of the line breaks! You would need to replace the spaces with /n. Check here : SendGrid multiple lines - #2 by theadaloguy
I just tried Nathan’s suggestion with ChatGPT API and it worked! But you need to encode the value first. You can use a API, the encode component or the Pragamaflow js component!
Thank you
