Sync External Configs to GitHub Variables via Webhook
External systems post config updates to Notis via webhook. Notis instantly grants repos access to GitHub Actions variables, keeping deployments in sync.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Add selected repository to an organization variable
Grants a repository access to an organization-level github actions variable, if that variable's visibility is set to 'selected repositories'.
Why this helps
CI/CD configs come from multiple sources (infrastructure tools, config services), but GitHub Actions variables are updated manually. Decoupling creates drift and deployment failures.
- Connect external systems directly to GitHub
- Sync configs in real time via webhook
- Eliminate manual variable management
- Reduce deployment failures from stale configs
Setup
Build it in a few focused steps.
- 1Connect your GitHub integration to Notis.
- 2Tell Notis: 'When you receive a configuration via webhook, automatically grant the right repositories access to the matching GitHub Actions variables.'
- 3Provide the webhook endpoint details (Notis generates a secure URL).
- 4Configure your external system to send updates to the Notis webhook.
- 5Test by sending one configuration update from your external system.
Questions about this workflow
How does Notis know which repos get which variables?
Provide a mapping in Notis: 'config-name maps to repo-X and grants access to variable-Y.'
Can multiple repos share variables?
Yes. Notis grants access to all specified repos.
What if the webhook format changes?
Tell Notis how to parse your webhook format, and it adapts.

Supported Triggers and Actions
Notis builds workflows that link Notion to GitHub. A trigger fires from one place; an action lands in another.
Notion triggers
GitHub actions
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Accept a repository invitation
Accepts a pending repository invitation that has been issued to the authenticated user.
Comment Created
Triggers when a new comment is created in Notion. Optional `page_id` filter scopes to comments on a specific page. When omitted, fires for any new comment in the workspace the integration has access to. Requires the 'Read comments' capability on the Notion integration. If a connection was authorized before that capability was enabled, the user must re-authorize the connection for comment events to flow.
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.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
List stargazers
Deprecated: lists users who have starred a repository; use `list stargazers` instead.
Database Created
Triggers when a new Notion database (the container) is created. A database is the post-2025-09-03 container that holds one or more data sources. This trigger fires for the container's creation event (`database.created`), distinct from `NOTION_DATASOURCE_CREATED` which fires when a new data source is added to an existing database. Most customers calling Notion's `POST /v1/databases` (the legacy API) or creating a database via the Notion UI will see this event. Adding a new data source to an existing database fires `data_source.created` instead — use `NOTION_DATASOURCE_CREATED` for that. Notion's payload puts `entity.type: "block"` (the container is a `child_database` block in the content tree) and `entity.id` is the database id.
Star a repository for the authenticated user
Deprecated: stars a repository for the authenticated user; use `star a repository for the authenticated user` instead.
Data Source Created
Triggers when a new Notion data source is created. Fires workspace-wide. The payload's `data.parent` carries the data source's tree parent (typically the teamspace) for downstream filtering. A single template-based database creation can fire multiple `data_source.created` events at once — one per data source the template instantiates.
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.
Data Source Schema Updated
Triggers when a Notion data source's schema is updated. Fires on column add / remove / rename. Payload includes `data.updated_properties: [{id, name, action}]` so consumers can discriminate the kind of change downstream. Optional `data_source_id` filter scopes to schema changes on a single data source. When omitted, fires for any schema change in the workspace the integration has access to. Note: adding a column also fires `page.properties_updated` once per existing row in the data source. Customers wanting a single structural-change signal should use this trigger.
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.
New Page
Triggers when a new page is added to a Notion database.
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.
Page Added to Page
Fires when a new subpage (a `child_page` type block) is added under a specified parent Notion page.
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.
Connect any two apps with Notis in the middle.
