403 response from OAuth token request

Hi, dear Zoom community

I am receiving 403 response when trying to get an OAuth token. I have whitelisted both server URL and redirect URL in the app.

Here is the code which is doing post request to the Zoom server

            .uri {
                    .queryParam("grant_type", "authorization_code")
                    .queryParam("code", code)
                    .queryParam("redirect_uri", "http://***/zoom")
            .header("Authorization", "Basic $id:$secret")
            .header("Content-Type", "application/json")

Here is the error which I get

org.springframework.web.reactive.function.client.WebClientResponseException$Forbidden: 403 Forbidden from POST https://zoom.us/oauth/token?grant_type=authorization_code&code=***&redirect_uri=http%253A%252F%252F***%252F%2523%252Fzoom

I would be grateful for any advice

Hi @vasia,

Happy to help! Did you also whitelist the development and production url?


Hi @gianni.zoom,

Yes, I whitelisted the domain, all subdomains, and full URLs which can be related to this, but nothing helps, still 403

Hey @vasia,

When you encounter the 403 response, are you seeing a response body as well containing an error message? If so, can you share that response body here?
