Affirm

How to start taking Affirm payments

Affirm approves each business before issuing live credentials, so the setup is an application first and a two-minute copy-paste after. You need a US business entity and a US bank account; your customers need a US mobile number. Payments are in USD.

1. Apply for an Affirm business account

Apply at affirm.com/business with your US business details and bank account. Affirm underwrites the business — travel and experiences are a category Affirm actively serves — and approval typically takes one to five business days. Your account then opens the Affirm Merchant Portal.

2. Copy your API keys

In the Merchant Portal open the API keys page. Every account has two key pairs: a sandbox pair for testing and a production pair for real payments — each pair is a public API key and a private API key. Keys are bound to their environment: sandbox keys can never take a live payment, and vice versa.

3. Activate Affirm in TourTask

In TourTask go to Configuration → Payment options, add Affirm, choose USD, paste the production public and private API keys, and press Activate. Customers then see "Pay over time with Affirm" on your booking page, complete the loan on Affirm's own page, and the booking confirms the moment they return. You are paid the full amount upfront; Affirm collects from the customer over time.
