Getting Started#

This integration creates a workflow with a Eversign trigger and Node action. When you configure and deploy the workflow, it will run on Pipedream's servers 24x7 for free.

Select this integration
Configure the New Event trigger
1. Connect your Eversign account
2. Configure API Key
3. Select one or more Events
Configure the Run Node Code action
1. Connect your Node account
Deploy the workflow
Send a test event to validate your setup
Turn on the trigger

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.

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:

Node Overview#

Develop, run and deploy your Node.js code in Pipedream workflows, using it between no-code steps, with connected accounts, or integrate Data Stores and File Stores.

This includes installing NPM packages, within your code without having to manage a package.json file or running npm install.

Below is an example of installing the axios package in a Pipedream Node.js code step. Pipedream imports the axios package, performs the API request, and shares the response with subsequent workflow steps:

  async run({
    steps, $,
