I get a 401 error, what should I do?
Hey Yuri, I faced this error too with SendGrid. I suggest using SendInBlue instead. The setup and documentation are clearer on the latter.
I Included the required authentication within the header paramters.
The json in the body of the email is taken from this link.
This appears to be a problem on Sendgrid’s side not on Adalo’s. Please could you reach out to the sendgrid support team to ask them what the problem may be.
