New Event on Eversign

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:

AWS Overview#

The AWS API unlocks endless possibilities for automation with Pipedream. With this powerful combo, you can manage your AWS services and resources, automate deployment workflows, process data, and react to events across your AWS infrastructure. Pipedream offers a serverless platform for creating workflows triggered by various events that can execute AWS SDK functions, making it an efficient tool to integrate, automate, and orchestrate tasks across AWS services and other apps.

Action Authentication#

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

Follow the AWS Instructions for creating an IAM user with an associated access and secret key.

As a best practice, attach the minimum set of IAM permissions necessary to perform the specific task in Pipedream. If your workflow only needs to perform a single API call, you should create a user and associate an IAM group / policy with permission to do only that task. You can create as many linked AWS accounts in Pipedream as you'd like.

Enter your access and secret key below.
