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.

Typeform Overview#

With the Typeform API, you can easily create beautiful, interactive forms that
allow people to share their information with you in an engaging way. Here are
some examples of what you can build with the Typeform API:

A contact form for your website that allows people to easily get in touch
with you
An order form for your product or service that allows people to place orders
easily and securely
A survey form that allows you to collect data and feedback from people
A registration form for your event or conference that allows people to sign
up easily and securely

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
Typeform	`typeform`	`app`	This component uses the Typeform 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.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Form	`formId`	`string`	Select a value from the drop down menu.

Trigger Authentication#

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

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

offlineaccounts:readforms:writeforms:readimages:writeimages:readthemes:writethemes:readresponses:readresponses:writewebhooks:readwebhooks:writeworkspaces:readworkspaces:write

Verify List of Email Address on Verifalia

Description:Verify a list of email address and check if it is properly formatted, really exists and can accept mails, flagging spam traps, disposable emails and much more. [See the docs](https://verifalia.com/developers#email-validations-creating) for more information

Verifalia Overview#

The Verifalia API is a powerful and secure suite of tools designed to validate
& clean data and email addresses. It can be used to help reduce fraud, improve
data quality, and boost marketing campaigns.

Verifalia's API can be used to build the following:

Email Validation: Validate a list of email addresses and check for accuracy,
validity, and deliverability.
Email Address Hygiene & Cleaning: Automatically clean a list of email
addresses to remove duplicates, typos, and invalid addresses.
Email Address List Verification: Check a list of email addresses and verify
them against a specific domain.
Email Spam Score & Analysis: Analyze a list of emails and determine the
associated spam level.
Phone Number Validation: Automatically validate a list of phone numbers and
check for accuracy and improper formatting.
Bulk Email Sending: Execute a bulk email campaign and track email delivery
rate in real-time.
Private DNS Check & Domain Name Verification: Check a domain's reliability
and identity, as well as DNS records and MX records.
Domain Catch-all Check & Delivery Confirmation: Determine if a domain is
flagged as a catch-all and confirm if emails sent to that domain will be
received by the intended recipient.

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 Addresses	`emailAddresses`	`string[]`	Enter a list of 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.
