How can I customize contribution amounts using URL parameters for my Numero Contribution Page?

You can customize the preset contribution amounts displayed on a contribution page by passing them directly in the page URL. This allows you to tailor suggested amounts for specific donors, campaigns, or outreach links without updating the page’s default settings.

This feature is especially useful for email campaigns, segmented donor outreach, or personalized fundraising links.

Overview

By appending an amounts query parameter to a contribution page URL, you can define exactly which preset contribution amounts appear when the page loads.

• Overrides the default contribution amounts
• Requires no changes to page configuration
• Works on a per-link basis

How to Customize Contribution Amounts

Step 1: Start with Your Contribution Page URL

Identify the standard URL for your contribution page. For example:

<code>https://secure.numero.ai/contribute/mattiematicasforus

Step 2: Add the amounts Parameter

Append ?amounts= to the URL, followed by a comma-separated list of numeric values.

Example

<code>https://secure.numero.ai/contribute/mattiematicasforus?amounts=5,10,15,20

This link will display $5, $10, $15, and $20 as the preset contribution options. The contribution page reflects these values immediately and no backend or page-level configuration changes are required.

Rules & Best Practices

• Format: Amounts must be numeric and comma-separated
  ✅ amounts=25,50,100
  ❌ amounts=25|50|100
• Overrides defaults: Any amounts passed via the URL replace the page’s configured preset amounts
• Link-specific: Each unique URL can display different amounts
