Payment links are shareable checkout URLs you create from the admin dashboard. Customers open the link, choose a payment method, and complete the payment - no invoice or API integration required. ## Create a payment link 1. Go to **Payments** → **Payment Links**. 2. Click **+ Create Link**. 3. Fill in the details (see options below). 4. Click **Create Link**. 5. Copy the shareable URL from the link list and send it to your customer. ## Link options | Option | Type | Required | Description | | ----------------- | ----------- | -------- | ----------------------------------------------------------------------- | | **Title** | Text | Yes | Name shown to the customer at checkout (for example "Consultation fee") | | **Description** | Text area | No | Additional instructions or details displayed on the checkout page | | **Amount** | Number | No | Fixed price. Leave blank to let the customer enter their own amount | | **Currency** | Select | Yes | Billing currency (must match a gateway that supports it) | | **Custom fields** | JSON schema | No | Extra input fields the customer must fill out (for example "Order ID") | | **Max uses** | Number | No | Maximum number of times the link can be paid. `0` means unlimited | | **Expires at** | Date/time | No | Link automatically deactivates after this date | | **Redirect URL** | URL | No | Where to send the customer after successful payment | | **Webhook URL** | URL | No | Custom webhook endpoint for this link only | ## Fixed vs. variable amount * **Fixed amount** - enter a value in the Amount field. The customer sees the price locked and cannot change it. * **Variable amount** - leave the Amount field blank. The checkout page shows an input where the customer types their own value. Use this for donations, tips, or flexible service fees. ## Expiry and usage limits Set **Max uses** to `1` for single-use links (for example a specific invoice payment). Set an **Expires at** date to prevent stale links from being used weeks later. When a link expires or reaches its use limit, customers see a "Link expired" message. ## Redirect URLs When a customer completes payment, they are redirected to the **Redirect URL** you configured. OwnPay appends `trx_id` and `status` as query parameters so you can confirm the result on your side. ## Embedding payment links You can embed a payment link in an `
