Retell deprecates single-agent fields

Hi, I’ve been catching data on zapier and using zapier to trigger phone calls on retell AI but now I’ve received an email to let me know that I’m using depreciated single-agent fields but it’s zapier who handle the actual payload, I just add the relevant fields on their UI. How do I fix this?

Hu Luke, do you mind sharing a screenshot of the error and the API you used to trigger Retell calls?
