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.

Twilio SendGrid Overview#

The Twilio SendGrid API opens up a world of possibilities for email automation, enabling you to send emails efficiently and track their performance. With this API, you can programmatically create and send personalized email campaigns, manage contacts, and parse inbound emails for data extraction. When you harness the power of Pipedream, you can connect SendGrid to hundreds of other apps to automate workflows, such as triggering email notifications based on specific actions, syncing email stats with your analytics, or handling incoming emails to create tasks or tickets.

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
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Twilio SendGrid	`sendgrid`	`app`	This component uses the Twilio SendGrid app.
N/A	`http`	`$.interface.http`	This component uses `$.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.
Event Types	`eventTypes`	`string[]`	Select a value from the drop down menu.

Trigger Authentication#

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

Verifalia Overview#

Verifalia's API provides robust email validation and verification services, ensuring that email addresses in your lists are accurate and deliverable. Leveraging Verifalia within Pipedream workflows can automate the process of cleaning up email lists, improve email marketing efficiency, and maintain communication channel integrity. By integrating Verifalia's capabilities, you can cut down on bounces, identify disposable email addresses, and segment lists based on quality scores.

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.

Label	Prop	Type	Description
Verifalia	`verifalia`	`app`	This component uses the Verifalia app.
Email address	`emailAddress`	`string`	Enter the email address to verify (e.g. `batman@gmail.com`)
Quality Level	`quality`	`string`	Select a value from the drop down menu:`{ "label": "Standard quality", "value": "standard" }{ "label": "High quality", "value": "high" }{ "label": "Extreme quality", "value": "extreme" }`
Data Retention Period	`retention`	`string`	The data retention period to observe for the validation job, expressed in the format `dd.hh:mm:ss` (where dd: days, hh: hours, mm: minutes, ss: seconds); the initial `dd.` part is added only for periods of more than 24 hours. The value has a minimum of 5 minutes (`0:5:0`) and a maximum of 30 days (`30.0:0:0`): Verifalia will delete the job and its data once its data retention period is over, starting to count when it gets completed.

Action Authentication#

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