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.

Label	Prop	Type	Description
Stack Exchange	`stack_exchange`	`app`	This component uses the Stack Exchange app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Site	`siteId`	`string`	Select a value from the drop down menu.
Questions	`questionIds`	`string[]`	Select a value from the drop down menu.
	`timer`	`$.interface.timer`

Trigger Authentication#

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

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

read_inboxno_expirywrite_accessprivate_info

the internet
A text messaging application that allows you to send and receive text
messages over the internet
A voicemail application that allows you to leave and receive voicemails over
the internet

Label	Prop	Type	Description
Twilio	`twilio`	`app`	This component uses the Twilio app.
From	`from`	`string`	Select a value from the drop down menu.

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.

To connect your Twilio account to Pipedream,

First, create an API key in Twilio.

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.

After creating your key, you'll see fields for Sid and Secret. Enter those in the fields below.

Visit your Twilio Dashboard. You'll see your Account SID listed near the top. Enter that in the AccountSid field below.
