Authenticate to the Airtable Web API with a personal access token

Documented steps
Create a token at https://airtable.com/create/tokens: name it, then add scopes — data.records:read for reads, data.records:write for create/update/delete, schema.bases:read for schema, webhook:manage for webhooks.
Grant resource access explicitly: '+ Add a base' (or all resources). A scope without a base grant gives no access to that base.
Copy the token immediately — it is shown once. Send it on every HTTPS request as 'Authorization: Bearer YOUR_TOKEN'.
Smoke-test with GET https://api.airtable.com/v0/{baseId}/{tableIdOrName} — a 200 with records confirms scope + base grant are both correct.

Known gotchas
Legacy API keys were deprecated (ended Feb 1, 2024) — 'key...' style keys fail; use PATs (pat...) or OAuth.
PATs never expire on their own; they die only when revoked or regenerated.
A PAT is capped by the creator's own collaborator permissions — e.g. schema changes need Creator-level access on the base, not just the schema.bases:write scope.
403 INVALID_PERMISSIONS_OR_MODEL_NOT_FOUND usually means the base was never added to the token's resource grants, not that the base doesn't exist.
