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 Row Created on Coda

Description:Emit new event for every created / updated row in a table. [See the documentation.](https://coda.io/developers/apis/v1#tag/Rows/operation/listRows)

Version:0.0.4

Coda Overview#

The Coda API enables you to interact with your Coda docs for both data retrieval and manipulation. By leveraging this API on Pipedream, you can automate document updates, synchronize data across different platforms, orchestrate complex workflows, and react to changes in real-time. Coda’s tables can act as dynamic databases that interconnect with various services, allowing you to streamline operations that depend on the timely and accurate exchange of information.

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
Coda	`coda`	`app`	This component uses the Coda app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
	`timer`	`$.interface.timer`
Doc ID	`docId`	`string`	Select a value from the drop down menu.
Table ID	`tableId`	`string`	Select a value from the drop down menu.
Include Updated Rows	`includeUpdates`	`boolean`	Emit events for updates on existing rows?

Trigger Authentication#

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

About Coda#

Coda is familiar like a doc and engaging like an app, so your team can jump in quickly, collaborate effectively, and make decisions that stick.

Action#

Delete Row(s) on PostgreSQL

Description:Deletes a row or rows from a table. [See the documentation](https://node-postgres.com/features/queries)

Version:2.0.6

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.

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.
