Ship hero if you use sso , it will not work because it doesn't provide a password to log in . Here is a repose from ship hero support . The error happens because ---- and your own login both sign in to ShipHero through your company's single sign-on (SSO). When an integration sends an email and password to the ShipHero API, ShipHero checks them against a ShipHero password. SSO users don't have one, so the API always answers "Wrong email or password", even when the password is correct for your company login. To connect an integration like Fivetran, use the tokens of a Third-Party Developer user instead. You already created one for this on November 2: Five.Tran.. Its tokens were generated successfully, and nothing has used them yet. To get them: Go to My Account > Developer Users: https://app.shiphero.com/dashboard/users Open the developer user . Copy the Refresh Token shown on that page. Enter the token in Fivetran's ShipHero connector setup. The Access Token is shown only once, when the developer user is created. If you didn't save it on November 2, or if Fivetran asks for an access token, you can get a new one at any time from the Refresh Token. Send a POST request to https://public-api.shiphero.com/auth/refresh with the body {"refresh_token": ""}. Access tokens last 28 days. The Refresh Token keeps working as long as the account is active and the developer user isn't deactivated. If Fivetran's ShipHero setup only offers email and password fields, please ask Fivetran support how to connect with a ShipHero API token instead. Please share tokens only through a secure channel.
