Auto Top-up ​

Auto top-up automatically adds funds to your account when your balance falls below a set threshold, ensuring your calls and campaigns never stop unexpectedly.

How It Works ​

  1. Your balance drops below the threshold you set
  2. Auto top-up triggers immediately
  3. Your saved card is charged for the refill amount
  4. Balance is updated automatically

Setting Up Auto Top-up ​

Prerequisites ​

  • [ ] Owner role (only Owners can configure)
  • [ ] Valid payment method saved in Stripe
  • [ ] Decide on threshold and refill amounts

Step-by-Step Setup ​

  1. Go to Settings → Billing
  2. Find the Auto-Fill section
  3. Toggle Enable Auto Top-up
  4. Configure:
SettingDescriptionRecommended
ThresholdBalance level that triggers a refillEnough to cover a few hours of usage
Refill AmountHow much to add when triggered ($10–$10,000)Enough to cover a campaign or day's usage
  1. Ensure a payment method is saved
  2. Click Save Settings

Configuration Options ​

Threshold Amount ​

When your balance falls below this amount, auto top-up triggers.

Set the threshold high enough that you won't run out of balance between the trigger and when the payment completes.

Refill Amount ​

How much to add when triggered. Set this high enough to cover your typical usage between top-ups.

Payment Method ​

Manage your saved card:

  1. Click Payment Methods in billing settings
  2. Add or update your card via the Stripe portal
  3. The same card is used for manual top-ups and auto top-ups

When Auto Top-up Triggers ​

Auto top-up activates when:

  • Balance falls below your threshold, and
  • Auto top-up is enabled, and
  • A valid payment method exists

An idempotency check prevents duplicate charges if the balance drops and recovers rapidly.

Managing Auto Top-up ​

Viewing Status ​

In billing settings, see:

  • Current status (enabled/disabled)
  • Current threshold and refill amounts

Changing Settings ​

  1. Go to Settings → Billing
  2. Modify the threshold or refill amount in the Auto-Fill section
  3. Click Save Settings
  4. Changes take effect immediately

Disabling Auto Top-up ​

  1. Go to Settings → Billing
  2. Toggle off Enable Auto Top-up
  3. Manual top-ups are still available at any time

  2. Ensure sufficient funds on the card
  3. Try a different card
  4. Contact your bank if persistent

Best Practices ​

For Campaigns ​

Before running a bulk campaign:

  1. Enable auto top-up as a safety net
  2. Set the threshold above your expected hourly spend
  3. Set a sufficient refill amount to cover multiple hours
  4. Also add manual funds so you start with a comfortable buffer
