The SDI allows you to set the following querystring parameters (which must be UrlEncoded) into a given donation url. This url is then presented to the donor and when clicked the donor will be taken to JustGiving's checkout with the following parameters pre-set to the form.
What type of pages does the SDI support donations for?
All links start with https://link.justgiving.com
What customisations can I add?
Combine variations of the below by adding a single ? and then separating each following parameter with &
|Name||Description||Supports Fundraising & Direct donations||Query String Parameter||Notes|
|CharityId||The unique id of the charity on JustGiving||Both||charityid=||Not to be confused with the charity's registration number.|
|Amount||A decimal number (optionally including two decimal places.) to pre-fill the donation amount.||Both||amount=||See list of minimum amounts supported|
|DonationValue||A decimal number (optionally including two decimal places.) to pre-set the donation value and bypass the amount step.||Both||donationValue=||See list of minimum amounts supported|

Example SDI urls
If the resulting checkout experience isn't as you tried to build, check your casing, check your values and check your URL structure. If a customisation can't be applied it will fall back to the normal checkout flow, it should not error out.
If the link takes you to https://www.justgiving.com/discover/featured then the page you're trying to donate to is likely to be expired, misconfigured or non-existent.
