POST request to Discord API returned 403 error

[Dmitry_Drynov]

Hello everyone,
I want to send a post request (client side) to Discord to create a message.

In the custom app (airtable block) I’m getting errors:

1. Problem with cors (I resolved it with anywhere-cors service)
2. After that I’m getting a 403 error.
   In Postman all cool.
