Payment Page Dynamic Links - PayRequest Documentation

Overview

Payment Page Dynamic Links allow you to create customized payment URLs with pre-filled information, making it easier for your customers to complete payments. These links can include customer details, product information, amounts, and even custom fields - all automatically populated when your customer clicks the link.

Dynamic links are perfect for email campaigns, invoices, customer portals, and any situation where you want to streamline the payment process.

Base URL Structure

Your payment page is accessible via a clean, branded URL:

https://payrequest.me/{your-handle}

Example:

https://payrequest.me/acme-corp

You can customize your handle in Settings → Payment Page. If you haven’t set a handle, your business name is used by default.

Language Support

Add language parameters to display your payment page in different languages:

Parameter	Language	Example
`?lang=en`	English (default)	`https://payrequest.me/acme-corp?lang=en`
`?lang=nl`	Dutch	`https://payrequest.me/acme-corp?lang=nl`

Example:

https://payrequest.me/acme-corp?lang=nl

All payment page text, buttons, and labels will automatically translate based on the selected language.

Query Parameter Format (Recommended)

The query parameter format provides maximum flexibility and readability. Basic Structure:

https://payrequest.me/{handle}?parameter=value&parameter2=value2

Supported Parameters

Parameter	Type	Description	Example
`product`	integer	Product ID to display	`?product=1814`
`amount`	decimal	Payment amount (EUR)	`?amount=25.50`
`method`	string	Pre-select payment method	`?method=ideal`
`name`	string	Customer name	`?name=John%20Doe`
`email`	string	Customer email	`?email=john@example.com`
`address`	string	Street address	`?address=Main%20Street%20123`
`city`	string	City name	`?city=Amsterdam`
`postal`	string	Postal/ZIP code	`?postal=1012AB`
`notes`	string	Payment notes	`?notes=Monthly%20subscription`
`lang`	string	Language (en/nl)	`?lang=nl`
`customfield_*`	string	Custom field value	`?customfield_size=large`

When a product parameter is provided, the amount is automatically set to the product price (including setup fees) and cannot be changed by the customer.

Common Use Cases

1. Product Payment Link

Direct customers to pay for a specific product:

https://payrequest.me/acme-corp?product=1814

What happens:

Product details are displayed (name, description, image)
Price is automatically set (including setup fees if applicable)
Amount field is hidden (customer cannot change price)
Recurring badge shown for subscription products

2. Pre-filled Customer Details

Send personalized payment links with customer information already filled in:

https://payrequest.me/acme-corp?product=1814&name=John%20Doe&email=john@example.com

Benefits:

Faster checkout experience
Reduced data entry errors
Professional customer experience

Enable “Readonly dynamic fields” in Settings → Payment Page to prevent customers from editing pre-filled information.

3. Complete Payment Request

Create a fully pre-configured payment link:

https://payrequest.me/acme-corp?product=1814&name=John%20Doe&email=john@example.com&address=Main%20Street%20123&city=Amsterdam&postal=1097CR&lang=nl

Includes:

Product information
Customer details
Address information
Language preference (Dutch)

4. Custom Amount Payment

For flexible payment amounts without a specific product:

https://payrequest.me/acme-corp?amount=150.00&name=John%20Doe&email=john@example.com&method=ideal

Use cases:

Donation requests
Partial payments
Flexible invoicing
Service deposits

5. Custom Fields Integration

Pass additional information using custom fields:

https://payrequest.me/acme-corp?product=1814&customfield_productcode=PROD-2024&customfield_size=large&customfield_color=blue

Custom field format:

Prefix: customfield_
Field name: Any alphanumeric name
Example: customfield_reference, customfield_order_number

Display: Custom fields appear in the “Additional Information” section on the payment page and are stored with the order.

Setup Fees Display

When linking to a product with a setup fee:

https://payrequest.me/acme-corp?product=1814

Automatic display:

Product price: €34.50/month
Setup fee: €100.00 (with custom name like “Borg” or “Installation”)
Total Today: €134.50

Setup fees are automatically included in the payment amount. The customer pays both the recurring price and setup fee in the first payment.

Recurring Products & Mandates

For subscription products with recurring payments:

https://payrequest.me/acme-corp?product=1859

Automatic behavior:

Payment page shows “Recurring” badge
Customer pays first installment + setup fee
SEPA mandate is automatically created during payment
Future payments process automatically using the mandate
Subscription becomes active after successful mandate creation

This only works with payment methods that support mandates (iDEAL, SEPA Direct Debit, credit card).

Read-Only Fields

Control whether customers can edit pre-filled information: Setting Location: Settings → Payment Page → Options → “Readonly dynamic fields” When enabled:

Pre-filled fields are locked (grayed out)
Customer cannot modify name, email, or other pre-filled data
Ideal for personalized payment requests

Example with read-only enabled:

https://payrequest.me/acme-corp?product=1814&name=John%20Doe&email=john@example.com

→ Name and email fields are visible but cannot be changed

Payment Page Settings

Configure payment page behavior in Settings → Payment Page:

Display Options

Setting	Description	Impact on Links
Show customer login	Display login prompt	Customers can log in to auto-fill their saved details
Show order notes	Display notes field	Customers can add custom notes to payments
Readonly dynamic fields	Lock pre-filled fields	URL parameters cannot be edited by customer
Page active	Enable/disable payment page	All payment page links return 404 when disabled

Amount Constraints

Minimum amount: Enforce minimum payment value
Maximum amount: Set upper limit for payments
Allow custom amount: Let customers enter their own amount

When using ?product= links, amount constraints are ignored as the product price is fixed.

Advanced Integration Examples

Email Campaign Links

Create personalized payment links for email campaigns:

<a href="https://payrequest.me/yourhandle?product=123&name={{customer_name}}&email={{customer_email}}&lang={{customer_language}}">
  Pay Now
</a>

CRM Integration

Generate dynamic links from your CRM:

const paymentLink = `https://payrequest.me/yourhandle?` +
  `product=${productId}` +
  `&name=${encodeURIComponent(customer.name)}` +
  `&email=${encodeURIComponent(customer.email)}` +
  `&customfield_reference=${orderId}` +
  `&lang=${customer.language}`;

Invoice Links

Add direct payment links to your invoices:

https://payrequest.me/yourhandle?amount={{invoice_total}}&name={{customer_name}}&email={{customer_email}}&notes=Invoice%20{{invoice_number}}

URL Encoding

Always encode special characters in URLs:

Character	Encoded	Example
Space	`%20`	`John Doe` → `John%20Doe`
@	`%40`	`user@example.com` → `user%40example.com`
&	`%26`	`Smith & Co` → `Smith%20%26%20Co`
#	`%23`	`Apt #5` → `Apt%20%23%5`

Most programming languages have built-in URL encoding functions (encodeURIComponent in JavaScript, urlencode in PHP, urllib.parse.quote in Python).

Security & Best Practices

✅ Do’s

URL encode all parameters to prevent formatting issues
Use HTTPS for secure payment page access
Enable read-only fields for personalized payment requests
Test links before sending to customers
Use product links for fixed-price items
Add language parameter for international customers

❌ Don’ts

Don’t include sensitive data like passwords or credit card numbers
Don’t rely on URL parameters for security (use proper authentication instead)
Don’t exceed URL length limits (keep under 2000 characters)
Don’t hardcode customer data without proper consent

Troubleshooting

Link doesn’t work

Check:

Payment page is active (Settings → Payment Page)
Product ID exists and belongs to your account
URL parameters are properly encoded
Handle is correct (case-sensitive)

Pre-filled data not showing

Causes:

Parameter names must be exact (lowercase)
Special characters need URL encoding
Product parameter overrides amount parameter

Customer can edit locked fields

Solution: Enable “Readonly dynamic fields” in Settings → Payment Page → Options

Wrong language displays

Fix: Add ?lang=nl or ?lang=en parameter to URL. Default is English.
