Action

Description:Adds a record to a table.
Version:1.0.3
Key:airtable-create-single-record

Airtable Overview

Using the Airtable API, you can build applications that can:

  • Create and manage databases
  • Add, update, and delete records
  • Search for records
  • Sort and filter records
  • Display records in a variety of ways
  • Import and export data

Action Code

import commonActions from "../../common/actions.mjs";
import airtable from "../../airtable.app.mjs";
import common from "../common.mjs";

export default {
  key: "airtable-create-single-record",
  name: "Create single record",
  description: "Adds a record to a table.",
  version: "1.0.3",
  type: "action",
  props: {
    ...common.props,
    // eslint-disable-next-line pipedream/props-label,pipedream/props-description
    tableId: {
      ...common.props.tableId,
      reloadProps: true,
    },
    typecast: {
      propDefinition: [
        airtable,
        "typecast",
      ],
    },
  },
  async additionalProps() {
    return commonActions.additionalProps(this);
  },
  async run({ $ }) {
    return commonActions.createRecord(this, $);
  },
};

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.

LabelPropTypeDescription
AirtableairtableappThis component uses the Airtable app.
BasebaseIdstringSelect a value from the drop down menu.
TabletableIdstringSelect a value from the drop down menu.
Typecasttypecastboolean

The Airtable API will perform best-effort automatic data conversion from string values if the typecast parameter is True. Automatic conversion is disabled by default to ensure data integrity, but it may be helpful for integrating with 3rd party data sources.

Action Authentication

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

Visit your account settings, copy your API key, and enter it below. If you only need to read data from Airtable, and not modify it, you can generate a read-only API key.
