When your Flowella subscription doesn’t cover an action, Flowella blocks it and tells you why. This page explains each message, which actions are blocked and how to get sending working again. For how plans and subscription states work, see Billing and Plans and limits.

What you see

The dialogs have two buttons: Not now closes the dialog, and View plans & usage opens Settings → Billing.

What is blocked

Without an active subscription, or once a payment has been past due for more than 7 days, Flowella blocks:
  • Replies, templates and Smart replies sent from the Inbox
  • Test Template sends and bulk sends, including Resend unsent
  • Create WA Flow and Sync WA Flow on the Flows page
  • Send WhatsApp Template steps in HubSpot workflows
  • Sending messages, sending templates, recording opt-outs, and creating, editing, submitting or test-sending templates through the Flowella API
On the free trial, reaching the 5,000-message limit blocks sends from the Inbox, bulk sends and messages sent through the API until you upgrade. On Starter and Pro, messages over your plan’s allowance aren’t blocked: they’re billed as overage. See Plans and limits. These keep working, so you can recover:
  • Signing in and viewing your contacts, conversations, templates and results
  • Receiving WhatsApp messages in the Inbox
  • Creating, editing, submitting and cloning templates in the app
  • Connecting WhatsApp numbers and HubSpot
  • Adding opt-outs on the Opt-outs page
  • Settings → Billing
Nothing is deleted while sending is blocked. For the full list, see When sending is blocked.

Restore access

Anyone in your organisation can open Settings → Billing and use every action on it, whatever their role, including updating the payment method and choosing a plan. Agree in your team who looks after the subscription, and ask them to restore access. See Who manages billing.
When Stripe can’t take a payment, the Billing page shows a Payment failed badge and everyone in your organisation gets a Payment failed notification. Sending keeps working for 7 days.
  1. Go to Settings → Billing.
  2. Select Update payment method and enter a working card.
  3. When Stripe takes the payment, the badge changes back to Active and sending works again.
See When a payment fails.
Go to Settings → Billing and select Upgrade to Starter or Upgrade to Pro, then complete Stripe Checkout. Sending works again once the Current Plan panel shows your plan with an Active badge. See Upgrade to a paid plan.
A cancelled subscription keeps working until the date on its Cancels badge, then your organisation moves to the Free plan. To send again, choose a plan in Settings → Billing.
Upgrade to Starter or Pro in Settings → Billing. Upgrading ends the trial straight away. To see how many messages you’ve used, open Usage.

API responses

When billing blocks an API request, Flowella returns one of these responses. A payment has been past due for more than 7 days:
This comes with the HTTP status 402. There is no active subscription, for example because the trial ended:
This comes with the HTTP status 403. Don’t retry these requests automatically. Show the message to the person who looks after billing so they can fix it. For other API errors, see Errors.

Common questions

The Billing page updates within a few seconds of Stripe confirming the payment. Reload the page and check that the Current Plan panel shows Active. If it doesn’t after a few minutes, contact support with your Stripe receipt.
The subscription belongs to the organisation, so the block applies to everyone in it.
The API follows the same rules as the app: you need an active subscription or the free trial to send. See Plans and limits for what each plan includes.

Still locked after paying?
