Details

This integration uses pre-built, open source 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 Configuration

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.
LabelPropTypeDescription
Google Cloudgoogle_cloudappThis component uses the Google Cloud app.
N/Ahttp$.interface.httpThis component uses $.interface.http to generate a unique URL when the component is first instantiated. Each request to the URL will trigger the run() method of the component.
N/Adb$.service.dbThis component uses $.service.db to maintain state between component invocations.
Pub/Sub Topic Nametopicstring

Pipedream will create a Pub/Sub topic with this name in your account,
converting it to a valid Pub/Sub topic name.

Trigger Authentication

Google Cloud uses API keys for authentication. When you connect your Google Cloud account, Pipedream securely stores the keys so you can easily authenticate to Google Cloud APIs in both code and no-code steps.

When you create a service account in GCP, you'll be asked to generate a service account key. Create that key and download the key details in JSON format.

Open the key JSON in a text editor, then copy and paste its contents here.

Action Configuration

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI.

LabelPropTypeDescription
Discord WebhookdiscordWebhookappThis component uses the Discord Webhook app.
messagemessagestring

Enter a simple message up to 2000 characters. This is the most commonly used field. However, it's optional if you pass embed content.

Thread IDthreadIDstring

If provided, the message will be posted to this thread

embedsembedsany

Optionally pass an array of embed objects. E.g., {{ [{"description":"Use markdown including *Italic* **bold** __underline__ ~~strikeout~~ [hyperlink](https://google.com) `code`"}] }}. To pass data from another step, enter a reference using double curly brackets (e.g., {{steps.mydata.$return_value}}).
Tip: Construct the embeds array in a Node.js code step, return it, and then pass the return value to this step.

usernameusernamestring

Overrides the current username of the webhook

Avatar URLavatarURLstring

If used, it overrides the default avatar of the webhook

Action Authentication

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

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

About Pipedream

Stop writing boilerplate code, struggling with authentication and managing infrastructure. Start connecting APIs with code-level control when you need it — and no code when you don't.
