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

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.

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 Authentication

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

In Twilio, create an API key. There are two types of keys: Master and Standard. You'll need a Master key to interact with certain API endpoints, like /Accounts. If you don't need to interact with those endpoints, you can use a Standard key.

Once created, you'll receive an Sid and Secret here that you should enter in the corresponding fields below.

Then, in your Twilio Dashboard, you'll see your Account SID listed near the top. This is required for certain API operations. Enter that in the AccountSid field below.
