Make your first API call.

The Appenda API reads and changes the tables, records and enrichment runs in a cloud workspace. Every request is HTTPS, sends JSON and answers JSON. This page takes you from no key to a working call in four steps.

1. Create an API key

1. Sign in at appenda.app/account and open API keys.
2. Pick the workspace, type a name and choose Create key.
3. Copy the secret. It is shown once.

The key belongs to that workspace, so every request with it reaches that workspace. No workspace id goes in the path.

2. Save the key in your shell

export APPENDA_API_KEY="appenda_sk_live_..."

3. List your tables

curl https://api.appenda.app/v1/tables \
  -H "Authorization: Bearer $APPENDA_API_KEY"

4. Read the reply

{
  "data": [
    {
      "id": "tbl_67ad65ba34a7bbfc643711b8531cba3f",
      "name": "Series B SaaS accounts",
      "created_at": "2026-09-14T09:12:44.000Z",
      "updated_at": "2026-10-21T13:58:02.000Z"
    }
  ],
  "meta": {
    "next_cursor": null,
    "has_more": false
  }
}

Everything you asked for is under data. A list also says whether there is another page; see Pagination.
