Currently we do not have a specific donations button, we are working on providing one soon.
However, you can still create one manually using the regular buy now button and allowing the option to the user to enter the amount.
To create a buy now button without an exact amount:
-----------------------------------------------------------------------------
1- Log into AlertPay
2- Click: Business Tools
3- In the section: Advanced Integration
Click: Generate buy now button
4- Enter all the required fields. For the amount you may enter any amount for now, (for instance 2.00)
5- In the button code that is generated after, please change the following line
<input type='hidden' name='ap_amount' value='2.00'/>
with
<input type='text' name='ap_amount' value=' '/>
Now when the client goes to pay on your website, they will need to enter the amount they wish to pay before they click the buy now button.
