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.

Escalation PoliciesescalationPoliciesstring[]Select a value from the drop down menu.
Interval to poll for new rotationstimer$.interface.timer

The PagerDuty API doesn't support webhook notifications for on-call rotations, so we must poll the API to check for these changes. Change this interval according to your needs.

Trigger Authentication

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

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

const { phone } = require("phone");

LabelPropTypeDescription

FromfromstringSelect a value from the drop down menu.
Totostring

The destination phone number in E.164 format. Format with a + and country code (e.g., +16175551212).

texttextstring

The text you'd like Twilio to speak to the user when they pick up the phone.

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.
