Webhook trigger fires once then goes silent — no error, no retry
The silent failure usually means your payload exceeds the 100KB limit. Check your record count — if you're passing full linked records instead of just IDs, you'll hit this wall fast. Add a 'Limit record fields' step before the webhook action and test with a single record first.
Stakes escalate from formula fixes to multi-table architecture. Someone here has mapped every tunnel.
Your rollup returns zero and you don't know why.
You've checked the field type. You've refreshed the page. You've rebuilt the rollup from scratch. Still zero. The linked records are there — you can see them — but the count refuses to acknowledge them.
ROLLUP returns 0 on linked records that clearly have values — junction table issue?

Classic junction table trap. Your ROLLUP is pointing at the junction table, not the final destination table. You need a second linked field from junction → destination, then ROLLUP from there. Draw it out: Table A → Junction → Table B. The rollup lives on Table A, traverses Junction, counts Table B.

The webhook fires once, then goes silent forever.
You built the automation. You tested it. It worked perfectly. You deployed it. Now it's Wednesday midnight, the trigger should have fired six times, and your Slack is silent. No error. No log. Nothing.
You're building a client portal and the permissions logic is eating you alive.
Three client types. Two interface views. One base. You need Client A to see only their records, Client B to see aggregates, and your team to see everything — without duplicating the base or creating a maintenance nightmare that collapses in six months.
Multi-tenant client portal in Airtable — interface permissions without base duplication

The cleanest solution I've seen at scale: one base, one Clients table with a Type field, filtered interface pages per type using the record link as the permission gate. Each client sees a page filtered to their own record ID. No duplication. The key insight is using the interface's "Start from a record" feature as your access control layer.
