I’m having trouble defining why my Zap returns an error. It did work before, but stopped working without me interfering.
The Zap runs customer data from Plug&Pay to Convertkit.
On the Convertkit end it returns this;
Unexpected status code 404 from https://api.convertkit.com/v3/tags/-234/subscribe
I’ve checked for the API/account connection which seems fine.
Anyone any suggestions?
