Connect REST API to Airtable

Point at any JSON REST API, handle pagination and auth, pull the records out and land them in your destination. The escape hatch for any tool without a dedicated connector.

What you can pull from REST API

A REST API job pulls records into a flat table on your schedule. Nested fields are flattened into ordinary columns, so what lands in Airtable is ready to sort, filter and total rather than needing another cleanup step.

  • Any JSON endpoint
  • Page / offset / cursor paging
  • Bearer, header or query auth

Options you can set

url
The full request URL
method
GET or POST — defaults to GET
records_path
Dot path to the array holding your rows, e.g. data.items
pagination
none, page, offset or cursor — defaults to none
page_size
Records per page, up to 1,000 — defaults to 100
max_pages
Safety cap on the paging loop, up to 1,000 — defaults to 50
timeout
Per-request timeout in seconds, up to 300 — defaults to 30

How it lands in Airtable

Airtable accepts append, upsert writes. Upsert is the one that matters on a schedule: it merges on a key you choose, so matching rows are updated in place and only genuinely new records are created. Append instead, and a daily job multiplies your data.

Upsert merges on up to three key fields. Matching records are updated in place; only genuinely new rows are created.

  • At most 3 merge fields - Airtable rejects more.
  • Writes go 10 records per request, at 4 requests per second by default (Airtable’s own ceiling is 5) - roughly 2,400 records a minute.
  • typecast is on by default, letting Airtable coerce strings into select, number and date fields rather than rejecting the write.
  • unknown_fields defaults to error, so a renamed source column fails loudly instead of silently dropping data. Set it to skip if you would rather drop.

Authentication

REST API authenticates with an API key held as a stored connection, so it never appears in a spreadsheet cell, a formula, or a shared copy of a sheet.

Keeping runs incremental

Yes. Most APIs accept an updated-since query parameter; set it in query_params and the run fetches only what changed.

Pair a narrowed read with an upsert write and a re-run costs almost nothing: the rows it already knows are updated, and nothing is duplicated. That combination is what makes a frequent schedule affordable.

Limits and pacing

These are the provider-side ceilings that shape a schedule, not ours. Knowing them up front is the difference between a job that runs quietly every morning and one that starts failing the week your data grows.

Common gotchas

Most of what goes wrong with a scheduled sync is not a bug — it is a detail of how one side behaves that nobody wrote down. These are the ones that come up for this pair.

Cursor pagination reads the cursor from the response body

The next cursor is taken from a dot path inside the JSON body, and may be either an opaque token or a full next-page URL. APIs that return their cursor in a Link response header instead - Shopify’s REST Admin API and the GitHub API among them - cannot be followed past page one. Page and offset pagination are unaffected.

The URL is re-validated on every page

With cursor pagination the next URL comes from the response, which makes it attacker-influenced. It is checked again before each request rather than trusted because the first one passed.

Do not key an upsert on email

People change their email address. When they do, upsert cannot match, so it creates a second record - the exact duplicate you were trying to prevent, plus a stale one. Use a stable ID from the source system.

The key field has to be written

If you restrict which columns get written and the key field is not among them, there is nothing to match on and every row is treated as new.

A row that is a fact per period needs a compound key

For a daily history, one row is one entity per day. Key on the entity alone and each day overwrites the last, leaving no history at all.

Set it up in four steps

  1. 1

    Connect REST API

    Optional. A stored credential is sent as a bearer token, a named header, or a query parameter - never pasted into a spreadsheet cell.

  2. 2

    Connect Airtable

    Connect your Airtable account once, then pick a base and table.

  3. 3

    Shape the data

    Select the columns you want, filter rows, cast types and add computed fields. Everything else is dropped before it reaches the destination.

  4. 4

    Schedule it

    Run once, or on a cron. Every run refreshes Airtable with the latest REST API data.

Do I need an add-on or extension for this?

No. The job runs server-side and writes into Airtable through its API, so there is nothing installed in the destination itself. It keeps running when nobody has the file open, and a copy of the file does not need anything installed to work.

How often does the data refresh?

On whatever schedule you set with a cron expression — hourly, daily, or a specific time on specific days. Each run pulls the latest from REST API.

Do I need to write any code?

No. You connect both sides, map the fields in a wizard and set a schedule. Computed fields accept small expressions — abs, round, min, max, len — but there is nothing to host or maintain.

What if my API is not in the connector list?

That is what this connector is for. If it speaks JSON over HTTP, point the REST source at it, set the path to the array holding your rows, and pick a pagination style.

Where does my API key live?

In a stored connection, sent as a bearer token, a named header or a query parameter at request time. It is never written into a spreadsheet cell or a formula, which is the usual failure mode of script-based approaches.

How do I stop duplicate records appearing?

Use upsert rather than append, and key it on a stable identifier from the source. Append creates new records every run, so a daily job leaves seven copies of every row by the end of the week.

How fast can it write?

Airtable accepts 10 records per request, and writes are paced at 4 requests a second by default against a ceiling of 5 - roughly 2,400 records a minute. That is comfortable for thousands of rows and worth planning around for hundreds of thousands.

Is the REST API connector free to use?

You can connect REST API and start syncing on the free plan.
