Hello @Kateryna most likely you’re own grant has expired. Go to your dashboard and check. I had situations were my own samples start failing due to the same reason…

@Blag Do I understand correctly, I need to check my Client ID or grand user?
I get the Client ID from my account, and this grand user does not exist. I send a token to the request and should receive a grand in response, and the user must appear in my account Nylas.

@Blag i have problem with my client id which i use for develop. When i try other account for production all works corectly.

@Kateryna What I mean is…

  • Go to your dashboard and check if your own grant is valid or not
