Manual review request: 403 "Lightning dunning decision is deny" — project gen-lang-client-05747829

Gemini API

Hello Google AI / Gemini Team,

My project gen-lang-client-05747829.. (project number: 1504270823..) is returning a 403 PERMISSION_DENIED on Gemini API calls:

{
“error”: {
“message”: “Lightning dunning decision is deny for project: projects/1504270823..”,
“code”: 403,
“status”: “Forbidden”
}
}

The billing account is active and in good standing. Between Aug 12–15, 2026, three automatic threshold charges were declined for insufficient funds. However, I resolved the balance via manual payments totaling CA$442.90 across that same window (Aug 13: -$103.55, -$100.00; Aug 14: -$20.00, -$95.00; Aug 15: -$100.00, -$104.35).

The account current ending balance is CA$0.01 (effectively zero). Billing account 01CC47-A07A7D-4699.. is Active, and gcloud billing projects describe confirms billing is enabled and linked.

It appears the dunning risk flag was triggered by the rapid threshold declines and was not automatically released when the manual payments settled.

Troubleshooting steps completed:

  • Verified active billing link and quota project on gen-lang-client-05747829..
  • Unlinked and relinked the billing account to trigger an account state refresh
  • Confirmed no stale API keys or invalid credentials exist in the local environment

Could someone please review and lift the dunning block on project 1504270823..? I can provide any additional billing verification details privately if needed.

Thank you!

Hello @savegelysubtle ,

The project my-popstpay... (project number 150427082...) is linked to a different billing account (011296-C84AE8-51...) than the one you updated.

  • Project gen-lang-client-05747829... (project number 223220323...) is linked to active billing account 01CC47-A07A7D-46... and has resumed active serving.
  • Project my-popstpay... (project number 150427082...) is attached to billing account 011296-C84AE8-51..., which remains restricted from earlier payment declines.
