Pause a Trading Repository Run from an Alpaca Alert
When an alert calls for a pause, send its repository and run details to Notis to cancel the matching cancellable workflow run.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Cancel a workflow run
Cancels a workflow run in a github repository if it is in a cancellable state (e.g., 'in progress' or 'queued').
Why this helps
A trading-related automation can continue running after a market alert signals that someone should pause and review.
- Bring a specified run to a stop from an incoming alert
- Avoid searching GitHub manually during a time-sensitive review
- Keep a run report in the channel you choose
Setup
Build it in a few focused steps.
- 1Connect Alpaca and GitHub once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it for pausing a trading run.
- 3Tell Notis to cancel the GitHub workflow run identified in an incoming Alpaca alert, only when the alert explicitly requests a pause.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real example containing a repository and a cancellable workflow run.
Questions about this workflow
Will this cancel every workflow run in the repository?
No. The instruction should identify a specific run from the webhook request. GitHub can cancel it only when it is in a cancellable state, such as queued or in progress.
Can Notis infer an Alpaca market alert without an incoming request?
No. Alpaca has no listed trigger event for this package, so an HTTP request to the Notis webhook starts the automation.

Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Accept a repository invitation
Accepts a pending repository invitation that has been issued to the authenticated user.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
List repositories starred by the authenticated user
Deprecated: lists repositories starred by the authenticated user, including star creation timestamps; use 'list repositories starred by the authenticated user' instead.
List stargazers
Deprecated: lists users who have starred a repository; use `list stargazers` instead.
Star a repository for the authenticated user
Deprecated: stars a repository for the authenticated user; use `star a repository for the authenticated user` instead.
Add email for auth user
Adds one or more email addresses (which will be initially unverified) to the authenticated user's github account; use this to associate new emails, noting an email verified for another account will error, while an existing email for the current user is accepted.
Add app access restrictions
Replaces github app access restrictions for an existing protected branch; requires a json array of app slugs in the request body, where apps must be installed and have 'contents' write permissions.
Add a repository collaborator
Adds a github user as a repository collaborator, or updates their permission if already a collaborator; `permission` applies to organization-owned repositories (personal ones default to 'push' and ignore this field), and an invitation may be created or permissions updated directly.
Add a repository to an app installation
Adds a repository to a github app installation, granting the app access; requires authenticated user to have admin rights for the repository and access to the installation.
