Hi,
I'm trying to connect to AdWords API using .Net Library. I'm trying to connect to API, but my the token of my official MCC account it's en pending approval, but I created a testing account and I don't get the connection because I need a token from OAuth2. Trying to get that token from OAuth2 I get an error "invalid_client: The OAuth client was not found" (see attachment).
Is something wrong in my data? (in the attachment image you can see where I'm taking the data)
Thank you,
