I’m having issues adding users to a Sendgrid list. I’m using the sendgrid plugin.
The workflow creates a contact. However once run it’s saying “SendGrid API error: this header value for Authorization is not correct null”
I’ve added “Bearer” infront of the API key and still no luck.
Another plugin asks for a “List ID” however I’ve no idea how to find this in send grid…
Cheers, and stay safe.
