Getting Started#

This integration creates a workflow with a Svix trigger and OpenAI (ChatGPT) 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 Received (Instant) trigger
1. Connect your Svix account
2. Select a Application ID
3. Select one or more Event Types
Configure the Create Transcription (Whisper) action
1. Connect your OpenAI (ChatGPT) account
2. Select a Audio Upload Type
3. Optional- Select a Language
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.

Svix Overview#

The Svix API enables developers to manage and automate webhooks with ease. By integrating with Pipedream, you can leverage serverless workflows to react to incoming webhooks, manage webhook endpoints, and send out messages to subscribed endpoints. Whether you're seeking to enhance your application's notifications system or streamline event-driven integrations, Svix's API, when combined with Pipedream's capabilities, provides a robust platform for automating and scaling your webhook infrastructure.

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
Svix	`svix`	`app`	This component uses the Svix 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.
Application ID	`appId`	`string`	Select a value from the drop down menu.
Event Types	`eventTypes`	`string[]`	Select a value from the drop down menu.

Trigger Authentication#

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