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 or Updated Row on PostgreSQL

Description:Emit new event when a row is added or modified. [See the documentation](https://node-postgres.com/features/queries)

Version:2.0.5

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.

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
PostgreSQL	`postgresql`	`app`	This component uses the PostgreSQL app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Polling Interval	`timer`	`$.interface.timer`	Pipedream will poll the API on this schedule
Schema	`schema`	`string`	Select a value from the drop down menu.
Table	`table`	`string`	Select a value from the drop down menu.
Identifier Column	`identifierColumn`	`string`	Select a value from the drop down menu.
Timestamp Column	`timestampColumn`	`string`	Select a value from the drop down menu.

Trigger 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 a static IP that you've configured from a VPC in Pipedream, and enabled the workflow to connect through that VPC

SSL Setup

Configure SSL on your PostgreSQL database by providing the CA (Certificate Authority), and choosing between Full Verification (default), or Skip Verification. Skipping verification is not recommended as this has serious security implications.

About PostgreSQL#

PostgreSQL is a free and open-source relational database management system emphasizing extensibility and SQL compliance.

Action#

Add Or Update Records on Grist

Description:Add records in a specified table or updates existing matching records. [See the documentation](https://support.getgrist.com/api/#tag/records/operation/replaceRecords)

Version:0.0.1

Grist Overview#

Grist API on Pipedream enables you to automate data management tasks in your Grist documents. This might mean syncing data across different platforms, triggering notifications based on data changes, or processing data through custom logic. With Pipedream, you can use the Grist API to build workflows that react to events in real-time, connect to hundreds of other services, manipulate data in sophisticated ways, and create custom endpoints to integrate with your Grist data.

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
Grist	`app`	`app`	This component uses the Grist app.
Document ID	`docId`	`string`	The ID of the Grist document to operate on. You can find this in the Settings menu of the document.
Table ID	`tableId`	`string`	Select a value from the drop down menu.
Do Not Parse	`noParse`	`boolean`	Set to `true` to prohibit parsing strings according to the column type.
On Many	`onMany`	`string`	Select a value from the drop down menu:`{ "value": "first", "label": "The first matching record (default)" }{ "value": "none", "label": "Do not update anything" }{ "value": "all", "label": "Update all matches" }`
No Add	`noAdd`	`boolean`	Set to true to prohibit adding records.
No Update	`noUpdate`	`boolean`	Set to true to prohibit updating records.
Data Records	`records`	`string[]`	The data for the records to append or update. Each record should be a JSON-formatted string, mapping column names to cell values. Eg. `[ { "fields": { "pet": "cat", "popularity": 67 } } ]`. Instead of an id, a `require` object is provided, with the same structure as `fields`. If no query parameter options are set, then the operation is as follows. First, we check if a record exists matching the values specified for columns in `require`. If so, we update it by setting the values specified for columns in fields. If not, we create a new record with a combination of the values in `require` and `fields`, with `fields` taking priority if the same column is specified in both. The query parameters allow for variations on this behavior. Eg. `[ { "require": { "pet": "cat" }, "fields": { "popularity": 67 } } ]`

Action Authentication#

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

To retrieve your API key,

Navigate to your Girst account and sign in
