brokerages: signed webhook retry versus a green badge (2026-09-05)

Compare Investing fires a signed webhook for “investing apps for teens” in brokerages on 2026-09-05 across Binance, XP, and BTG. Focus: brokerages. Annual is blocked until a failed event retries without a 48h ticket.

How Binance, XP, and BTG hide the retry

Binance fails if the event is fire-and-forget. XP fails if brokerages only exists in a Zapier screenshot. BTG is the control: if its retry log is written, do not excuse the others.

Fails that kill broker-compare-2026-webhook-2026-09-05-s0

• Paying Binance annual with a badge and no secret
• Skipping the 500 test on XP
• Leaving brokerages inside a dead endpoint
• Closing before a timestamped retry

Go / no-go 2026-09-05

Annual only if the signed retry keeps brokerages for “investing apps for teens”. Otherwise broker-compare-2026 stays monthly until the dead-letter is written.
