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?
