'Die Spende' is the noun for the verb 'spenden' (to donate). While 'spenden' describes the action, 'die Spende' refers to the result—that is, the money, item, or substance that is given.
Er spendet regelmäßig für den Tierschutz.
He regularly donates to animal welfare.
In connection with money or items, 'Spende' is often combined with the verbs 'machen' (to make), 'sammeln' (to collect), or 'bitten' (to ask/request). You can make a donation or ask for a donation.
Die Organisation bittet um Spenden für die Opfer der Katastrophe.
The organization is asking for donations for the victims of the disaster.
When naming the purpose and recipient of a donation, you typically use 'für' (for) for the purpose and 'an' (to) for the organization.
Die Spende ist für ein lokales Umweltprojekt bestimmt.
The donation is intended for a local environmental project.
In the medical field, 'Spende' is often used as part of compound words. The most common are 'die Blutspende' (blood donation), 'die Organspende' (organ donation), and 'die Plasmaspende' (plasma donation).
Nach dem Unfall war er auf eine Blutspende angewiesen.
After the accident, he depended on a blood donation.

'der Beitrag' and 'die Spende' can both mean something that someone gives for a good or shared purpose. However, 'Beitrag' is more general: it can be money, but also work, time, or an idea. Also, a 'Beitrag' can be voluntary, but it does not always have to be. A 'Spende' is voluntary and usually goes to a charitable, nonprofit, or religious cause. The words can be confused when someone gives money for a project. For help with a collection or a club, 'Beitrag' can fit; for voluntary money given to an aid organization, 'Spende' is more precise.
