Hi there! 👋 I see you're having trouble adding credits to purchase add-ons for concurrency lines.
I don't have specific information about the exact error you're encountering, but I can definitely help with some troubleshooting steps and information about adding credits to your Vapi account.
Here are some troubleshooting steps you can try:
## Initial Troubleshooting Steps
* **Check your card details**: Make sure your card information is correct and up-to-date, including the card number, expiration date, and billing address. Look for any typos or outdated information.
* **Try a different payment method**: If possible, try using a different credit card or payment method.
* **Contact your bank**: Your bank might be blocking the transaction due to new restrictions or security measures.
* **Check for a frozen wallet**: If your credit balance is negative, your wallet may be frozen, preventing you from making purchases. A greyed-out "Buy Credits" button can indicate a frozen wallet.
## Adding Credits to Your Account
To add credits to your Vapi account, you should:
1. Navigate to the billing page at [
https://dashboard.vapi.ai/org/billing/credits](
https://dashboard.vapi.ai/org/billing/credits)
2. Specify the dollar amount of credits you want to purchase in the
credits
field
3. Complete the payment process
According to the [billing FAQ](
https://docs.vapi.ai/billing/billing-faq), Vapi uses a credit-based billing system where one credit equals one US dollar.
## Auto-Reload Feature
I notice in your screenshot that there's an "Enable Auto Reload" option. This is a helpful feature that automatically tops up your credits when they fall below a certain threshold. According to the [billing FAQ](
https://docs.vapi.ai/billing/billing-faq), auto-reload amounts must be at least $10, and it's recommended to set a threshold above $0.
