Zendesk Integrations

I am trying to use the Tymeshift api connector in Fivetran. Fivetran is having issues connecting to WFM api. I independently tried to call the api myself with a simple login curl and that doesnt work

curl --location 'https://myorg.tymeapp.com/l5/api/user/login' \

--header 'Content-Type: application/json' \

--data-raw '{

  "login": "myemail",

  "password": "redacted,

  "domain": "mycompany",

  "account_plan": "professional"

}'

this is what I got
{"success":false,"message":"Invalid credentials"}%        

so I tried with password and api key as well. has someone else faced this issue?
