Action

Posted by @pdavisonreiber, Last update about 4 years ago

To use this as part of one of your script actions, follow these steps:
- Download this script using the install button at the bottom of the page.
- Create a new action and use the “Include Action” step to include “Airtable API”.
- Add your own script to a “Script” action step after the “Include Action” step.
- Get your base’s endpoint and your API key from the Airtable API documentation.
- When prompted, enter these into the credential prompt. These details are stored locally on your device, and only need to be entered once for each base you access. To delete them, go to Credentials in the Drafts settings screen.

Airtable

Airtable is a web-based spreadsheet and database tool which can be used to organise a large variety of different kinds of data including text, images, files, and more. The scripting interfaces below are convenience wrappers that allow easy interaction with Airtable’s REST API.

While the Airtable API offers extensive read and write access to the data stored, it does not provide metadata about the structure of databases or the types of fields. Users will need to know this information in advance to properly interact with the database.

ATRecord

Represents a single record in an Airtable base.

Class Functions

create() -> ATRecord
- Create a new record object.
selectRecords(Array of ATRecord objects, field, options) -> Array of ATRecord objects
- Present a list of records to the user for them to select one or more
- Parameters
  - Array of ATRecord objects: all records must have been added to a table and the table updated.
  - field [string or function] : A string denoting the name of the field which should be used to represent the records in the selection list. Alternatively, pass a function which takes each record and returns a string to display. This can be used to combine multiple fields together to create the labels for the selection list.
  - options [object]: a dictionary of options with the following available keys.
    - title [string] (optional): Title to display in the prompt.
    - message [string] (optional): Message to display in the prompt.
    - type [string] (optional): Valid values are “selectMultiple”, “selectOne”, and “selectButtons”.
    - filter [function] (optional): A function to filter the records displayed.

Properties

id [string, readonly]
- The unique id of the record in the Airtable base. Undefined until the record is added to a table and the table is updated.
table [ATTable, readonly]
- The table to which the record belongs.
createdTime [date, readonly]
- The time that the record was created. Undefined until the record is added to a table and the table is updated.

Functions

getFieldValue(field) -> object
- Takes a string with the name of the field, and returns the contents of that field.
setFieldValue(field, object)
- Takes a string with the name of the field, and sets the contents of the field according to the object passed.
getLinkedRecords(field) -> Array of ATRecord objects
- For a field which links to records in another table, this returns all of the linked records. The table containing the linked records must have been added to the base.
linkRecord(field, ATRecord)
- For a field which links to records in another table, this adds a new linked record from the given field. Existing linked records are unaffected. Note that Airtable also supports linked fields which do not allow more than one linked record.
update() -> boolean
- Pushes changes to the base for a record that has already been added to a table. Returns true if successful.

ATTable

Represents a table within an Airtable base.

Class Functions

create(name, ATBase) -> ATBase
- Create a new table object with a given name and associated with a given base. Name must coincide exactly with an existing table on the web.

Properties

name [string, readonly]
base [ATBase]
records [Array of ATRecord objects]
- All of the records associated with the table.
fields [Array of strings]
- The names of the fields associated with records in the table.

Functions

addRecord(ATRecord)
- Add a new record to the table. Will not be pushed to the web until update() is called.
selectRecords(field, options)
- Equivalent to ATRecord.selectRecords(table.records, field, options).
update() -> boolean
- Push changes to the base. Returns true if successful.

ATBase

Represents an individual Airtable base.

Class Functions

create(name) -> ATBase
- Create new base object with given name.

Properties

name [string]
tables [Array of ATTable objects]
- All of the tables associated with the base.

Functions

getRecordWithID(id) -> ATRecord
- Takes the unique id of a record within an associated table and returns the record object.

Examples

var base = ATBase.create("Favourite Books");
var books = ATTable.create("Books", base);
var authors = ATTable.create("Authors", base);

var newBook = ATRecord.create();
newBook.setFieldValue("Title", "The Hobbit");
newBook.setFieldValue("Genre", "Fantasy");

var chosenAuthors = authors.selectRecords("Name", {title: "Select Author", type: "selectOne"});
var chosenAuthor = chosenAuthors[0];

newBook.linkRecord("Author", chosenAuthor);

books.addRecord(newBook);
books.update();
