What you'll need
  • A PYMSTR account (sign up for free)
  • Your API key (starts with pk_)
  • A server that can make HTTPS requests and receive webhooks

Step 1: Get your API key

Create one from the Dashboard under API Keys.

Step 2: Create a payment

Send a POST request to /v1/payments with your amount and currency.

Step 3: Share the payment URL

The response includes a paymentUrl — send it to your customer.

Step 4: Handle the webhook

Get notified when the payment completes via webhook.
