Details

This integration uses pre-built, source-available components from Pipedream's GitHub repo. These components are developed by Pipedream and the community, and verified and maintained by Pipedream.

To contribute an update to an existing component or create a new component, create a PR on GitHub. If you're new to Pipedream component development, you can start with quickstarts for trigger span and action development, and then review the component API reference.

Trigger

Description:Emit new event when a reviewer is added to a merge request
Version:0.1.2
Key:gitlab-new-review-request

GitLab Overview

The GitLab API provides programmatic access to your GitLab projects, allowing you to automate common tasks, manage issues, merge requests, and more. With the GitLab API on Pipedream, you can create customized workflows that integrate with other services, streamline your development process, and enhance project management. By leveraging the power of serverless, you can set up triggers for GitLab events and perform actions across a variety of apps without managing infrastructure.

Trigger Code

Trigger Authentication

GitLab uses OAuth authentication. When you connect your GitLab account, Pipedream will open a popup window where you can sign into GitLab and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any GitLab API.

Pipedream requests the following authorization scopes when you connect your account:

Action

Description:Creates and appends blocks to the specified parent. [See the documentation](https://developers.notion.com/reference/patch-block-children)
Version:0.2.15
Key:notion-append-block

Notion Overview

Notion's API allows for the creation, reading, updating, and deleting of pages, databases, and their contents within Notion. Using Pipedream's platform, you can build workflows that connect Notion with various other services to automate tasks such as content management, task tracking, and data synchronization. With Pipedream's serverless execution, you can trigger these workflows on a schedule, or by external events from other services, without managing any infrastructure.
