I'm following the steps described in this Slack tutorial on authorizing Postman. When I get to the end and try to request the token from Postman, the Slack OAuth window pops up and I can authorize.
On Postman however, I get an error message:
Could not complete OAuth 2.0 login. Check Postman Console for more details.
Checking the Postman console shows:
POST https://slack.com/api/oauth.access bad_client_secret Error
If checked and double checked, and I'm sure I copied the right client secret value.
Can anyone see what I'm doing wrong? Thanks!
