# One Time Charge Forms One time charge forms are exactly what they sound like. We use Stripe's API to create a one time charge on your behalf and **save the card while doing** so. This means if you need to later add a subscription to the customer, create another charge, or place a hold you can easily do so inside of Stripe without asking for the card again. Configuring a one time charge form can be done by logging into your InstaPayments account Going to Forms > One Time Charge Forms > Click the plus button in the bottom right. You'll see a screen that looks like this: ![](/files/-Lm5PMWd4gfSdQCRQTDj) Fill out the price you want to charge and the other required fields and hit Create. This will then send you back to a page where you can select "Copy Link". Once you've copied the form's unique link you can send it in an email, put the link behind a button on your website, put it in an iframe etc. If you have any questions, about one time charge forms please let us know by chatting with us on our website or by sending us a quick email at . --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
