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 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
N/A	`httpInterface`	`$.interface.http`	This component uses `$.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.
Body Only	`emitBodyOnly`	`boolean`	This source emits an event representing the full HTTP request by default. Select `true` to emit the body only.
Response Status Code	`resStatusCode`	`string`	The status code to return in the HTTP response
Response Content-Type	`resContentType`	`string`	The `Content-Type` of the body returned in the HTTP response
Response Body	`resBody`	`string`	The body to return in the HTTP response
HTTP / Webhook	`http`	`app`	This component uses the HTTP / Webhook app.

Trigger Authentication#

The HTTP / Webhook API does not require authentication.

PostgreSQL Overview#

Assuming you want a few paragraphs on what you can do with the PostgreSQL API:

The following examples demonstrate some of the things that can be done with the
PostgreSQL API:

Developing a custom storage engine for PostgreSQL
Adding a new data type to PostgreSQL
Creating a new function for PostgreSQL
Building a graphical user interface for PostgreSQL
And much more!

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.
Reject Unauthorized	`rejectUnauthorized`	`boolean`	If `true`, the server certificate is verified against the list of supplied CAs. If you encounter the error `Connection terminated unexpectedly`, try setting this prop to `false`.
Schema	`schema`	`string`	Select a value from the drop down menu.
Table	`table`	`string`	Select a value from the drop down menu.
Lookup Column	`column`	`string`	Select a value from the drop down menu.
Lookup Value	`value`	`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.

Before you connect to your PostgreSQL database from Pipedream, please make sure your database is either:

Accessible from the public internet (You may need to add a firewall rule on 0.0.0.0/0 on port 5432), or
Accessible from an SSH server that you route PostgreSQL requests through

After that, enter the following values:
