Hi @philipp.laengle107
Your Authorization header should not be empty
For example:-
Create an API key in sendgrid & copy the secret key & paste it like this
However when I try to add a user to the lists in send grid, I get the error as shown above. Does the workflow “Add Recipient to Sendgrid” work for you?
Hey there. Today I released a plugin that allows you to add contacts. Looks as though the plugin from copilot hasn’t been updated/supported for a while. It also doesn’t work with the latest API.
At some point I’ll also update other API endpoints but for now I have added the add/update a contact endpoint. You will need to use both plugins until all of the actions have been reproduced in this updated version. It’s called “SendGrid Pro”.
