Zexa uses a credit-based billing model. You purchase credits in advance and they are consumed each time you send a message. The number of credits used depends on the channel and the destination country — there is no recurring subscription required for basic use.

​
How credits work

Credits give you full control over your messaging spend. Before you buy, here are the key rules:
  • Credits are pre-purchased. You top up your balance and draw from it as you send. No monthly commitment is required.
  • Credits do not expire. Your balance carries forward indefinitely.
  • Credits are non-refundable once purchased, in accordance with Zexa’s Terms of Use.
  • Each channel and destination has its own per-message rate. Rates are applied automatically when a message is dispatched.

​

​
Top up your balance

1

Open the Billing section

In the Zexa dashboard, go to Billing → Buy Credits.
2

Select a credit package

Choose the package that best suits your expected usage. Larger packages offer better per-credit value.
3

Complete payment

Follow the on-screen payment flow. Zexa supports the payment methods listed at checkout.
4

Receive your credits

Credits are added to your account immediately after payment confirmation. You will also receive a receipt by email.

​
View usage history

Go to Billing → Usage to see a full per-message log. Each entry shows:
  • Channel — SMS, WhatsApp, Telegram, Email, or Slack
  • Recipient — the destination address or number
  • Credits used — the exact amount deducted for that message
  • Timestamp — date and time of dispatch
Click Export CSV to download your usage history for reconciliation or reporting purposes.

​
Low credit alerts

Set a minimum balance threshold so Zexa notifies you before you run out of credits.
  1. Go to Billing → Alerts.
  2. Enable Low Balance Notification.
  3. Enter the threshold value (e.g. 500 credits).
  4. Save your settings.
Zexa will send an email alert when your balance drops below the threshold.
Set a low-credit alert well above zero — messages in transit when your balance hits zero will fail to deliver.

​
Check balance via API

Retrieve your current credit balance programmatically with a GET /credits request. 
curl --request GET \
  --url https://api.zexa.ao/v1/credits \
  --header "Authorization: Bearer YOUR_API_KEY"
Example response: 
{
  "balance": 5000,
  "currency": "AOA",
  "updated_at": "2026-06-24T10:00:00Z"
}
Credits are tied to a single account and cannot be transferred to another account. If you manage multiple workspaces, each account maintains its own independent balance.
