Hey @shelar1423 - I will review this properly later today, but please make sure you're following the GitHub example. For example the OAuth section should explain how to use OAuth and also link to Slacks documentation so the user can check the scopes - github example here: https://trigger.dev/docs/integrations/apis/github

Also, for the overview, I've just improved GitHubs so it is a bit clearer. Basically we want to write about how you can use Slack with Trigger.dev - https://trigger.dev/docs/integrations/apis/github. Hope that helps!

@D-K-P sure , meanwhile let me know if the other PR on Airtable is fine .

Thank you. Almost there:

• The overview needs to describe what you can do with Slack and Trigger.dev, so in our case it is sending a messages to Slack
• For the scopes link - here is an updated URL to change (the one you added was legacy): https://api.slack.com/scopes
• For the task, please change the channel id to "< your-channel-id >"
• Could you add a full example 'Example usage' at the bottom of tasks page (see the github docs for an example), you can use one from the jobs showcase

[shelar1423]

@D-K-P sure will make the changes right now

@D-K-P check if this is fine
