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.

Trigger#

New Event on Eversign

Description:Emit new event when a new event occurs in EverSign. To begin receiving events, navigate to your Developer dashboard, and enter the URL of this source/workflow as the Webhook URL. https://eversign.com/api/documentation/webhooks

Eversign Overview#

The Eversign API enables you to automate document workflows by electronically signing, sending, and managing documents. With Eversign, you can create legally binding documents, send them out for signature, and track their status. This eliminates manual tasks, reduces errors, and speeds up the document handling process. Pipedream's integration with Eversign lets you trigger workflows based on document events, or perform actions like creating and sending documents automatically, thereby integrating seamless e-signature processes within your digital ecosystem.

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
Eversign	`app`	`app`	This component uses the Eversign 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.
API Key	`apiKey`	`string`	The API key for your account. You can find it in your developer settings.
Events	`events`	`string[]`	Select a value from the drop down menu:`document_createddocument_vieweddocument_sentdocument_signeddocument_declineddocument_forwardedsigner_removedsigner_bounceddocument_completeddocument_expireddocument_revokeddocument_cancelledemail_validation_waived`

Trigger Authentication#

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

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

Find Row on PostgreSQL

Description:Finds a row in a table via a lookup column. [See the documentation](https://node-postgres.com/features/queries)

Version:2.0.6

View on GitHub

PostgreSQL Overview#

On Pipedream, you can leverage the PostgreSQL app to create workflows that automate database operations, synchronize data across platforms, and react to database events in real-time. Think handling new row entries, updating records from webhooks, or even compiling reports on a set schedule. Pipedream's serverless platform provides a powerful way to connect PostgreSQL with a variety of apps, enabling you to create tailored automation that fits your specific needs.

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
PostgreSQL	`postgresql`	`app`	This component uses the PostgreSQL app.
Schema	`schema`	`string`	Select a value from the drop down menu.

Action Authentication#

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

Connecting to Restricted Databases

Either enable the shared static IP for this account below, or configure a VPC to deploy any workflow in your workspace to a private network with a dedicated static IP. Learn more in our docs.

SSL Setup

Configure SSL on your PostgreSQL database by providing the CA (Certificate Authority), and choosing between Full Verification, Verify Certificate Authority (CA), or Skip Verification. Skipping verification is not recommended as this has serious security implications.
