Send a Webhook to Airtable

You have a service that fires webhooks — a signup form, a payment provider, an e-commerce platform, a monitoring tool — and you want each event to land as a record in an Airtable base. The problem: the Airtable API won't accept the raw webhook. It expects a bearer token and a fields object whose keys match your table exactly, and the payload your source sends never looks like that.

Webhook Relay sits in the middle. It receives the incoming webhook at a stable public URL, transforms the payload into the Airtable "create records" format, and delivers it to the Airtable API — no glue server, no Zapier task limits, no maintenance.

How it works

1. Your source service POSTs its webhook to a Webhook Relay endpoint.
2. A transformation function parses the payload and builds an Airtable API request body.
3. Webhook Relay forwards that to the Airtable API with your token, and a new record appears in your table.

Step 1: Create an Airtable token and find your IDs

1. Go to airtable.com/create/tokens and create a personal access token with the data.records:write scope and access to your base.
2. Find your base ID (app...) and table name from the base's API docs page.

Step 2: Create a Webhook Relay output to the Airtable API

Create a bucket with a public input, then add an output pointing at the Airtable API:

• Output destination: https://api.airtable.com/v0/<BASE_ID>/<TABLE_NAME>
• Headers:
  • Authorization: Bearer <your-personal-access-token>
  • Content-Type: application/json

Step 3: Add a transformation function

Attach a function to the output that reshapes the incoming webhook into an Airtable record. Map the fields you care about to your table's column names:

-- incoming payload is in r.RequestBody
local body = json.decode(r.RequestBody)

local payload = {
  records = {
    {
      fields = {
        Name = body.name or "New event",
        Email = body.email or "",
        Amount = body.amount or 0
      }
    }
  }
}

r:SetRequestBody(json.encode(payload))

Each key under fields must match a column in your Airtable table and use a compatible value type.

Step 4: Point your source at the URL and test

Configure your source service's webhook to point at your Webhook Relay public URL. Trigger an event — or replay one from the Webhook Bin — and a new record appears in Airtable within seconds. If Airtable rejects the request, the Webhook Relay logs show the exact error so you can fix the field mapping.

Going further

• Fan out: send the same event to Slack, Notion or a Google Sheet at the same time with multiple destinations.
• Test locally first: inspect the real payload in the Webhook Bin before you write the mapping.
• Secure it: verify the source signature before forwarding so only legitimate events reach Airtable.
