Sendbot uses a credit system to bill for platform usage. Each action has a different cost based on the resources consumed.

​
How Credits Work

The credit system is straightforward:
  • Recurring Credits: Renew monthly with your plan
  • Purchased Credits: One-time purchases that never expire
  • Usage Priority: Recurring credits are consumed first, then purchased credits

​
Usage Table

​
Chat Sessions

Base reference rates (effective November 2, 2026). Current, authoritative charges are provided by the Sendbot usage pricing page, which reads the Go billing catalog. *Official WhatsApp and third-party messaging providers may charge separate fees. The 1,000-session column is an arithmetic example, not a prepaid plan or allowance.

​
When credits are deducted

  • New billable session: the channel’s base session credits are deducted. A public Web start may be charged before any recorded answer; some guarded flows defer the first debit until a qualifying interaction.
  • Continuing an active session: does not create another start charge. A new billable renewal can occur after the applicable 24-hour lease.
  • Direct API: pricing applies to a billable session, not to every HTTP request. API replies and continuations can have other resource charges.
  • Editor preview: authenticated Web preview does not consume session credits. AI and paid integrations may still cost extra.

​
Usage examples

  • 1,000 new Web sessions: 150 credits.
  • 1,000 new Direct API sessions: 75 credits.
  • 500 Web + 500 API sessions: 112.5 credits.
Credits are the billing unit. The BRL per-session references (R0.01WebandR 0.01 Web and R 0.005 API) are illustrative, not a fixed conversion rate for every plan or credit purchase. Review your workspace ledger for the exact debit.

​
AI and Content Generation

*AI Agent usage depends on the model and number of tokens used.

If you use your own API key, AI Agent does not consume Sendbot credits, only usage from your provider account.

​
Checking Your Balance

​
In the Dashboard

You can see your current credit balance in the top-right corner of Studio.

​
Low Balance Alerts

For prepaid workspaces, the system sends a low-balance email when the available credit balance reaches 20% or less of the workspace’s recurring credit allowance. The warning is throttled so the same workspace is not emailed more than once within 24 hours.
  • Above 20% of the allowance - No low-balance email
  • 20% or below - Low-balance warning
  • 0 credits - New prepaid usage is blocked until credits are available
Purchased credits are included in the available balance. They are not divided by 100 or displayed as currency: 996 credits means 996 credits.

​
Billing Models

For entry-level plans
  • Service stops when credits run out
  • Auto-recharge is available
  • Best for tighter spend control

​
Auto-Recharge

Configure auto-recharge so you never run out of credits:
  1. Open Workspace -> Subscription
  2. Enable Auto-Recharge
  3. Configure:
    • Trigger: a monetary threshold in the workspace billing currency
    • Amount: the monetary amount to charge when auto-recharge runs
The Studio shows both values in the workspace billing currency. Internally they are stored in the currency’s minor unit (for example, 1000 = R$ 10.00 when the billing currency is BRL). The trigger is converted to its current credit equivalent using the active pricing configuration before the balance comparison.

Transaction History

All transactions are recorded and can be reviewed:
  • USAGE_WEB: Web sessions
  • USAGE_API: API sessions
  • USAGE_WA_STANDARD: WhatsApp sessions
  • USAGE_AI_RESPONSE: AI usage
  • REFILL_PLAN: Plan renewal
  • REFILL_TOPUP: One-time top-up
