Why this matters in South Africa
South African non-profits manage grant reporting, donor communication, programme delivery, and compliance reporting to the DSD simultaneously — often with a small team and limited systems budget. The average NPO spends 30% of admin time on manual grant reporting that could be automated.
Compliance note: NPOs must be registered with the Department of Social Development. PBO status for tax exemption requires SARS registration under Section 18A. Organisations receiving foreign funding must comply with the NPO Act and applicable SARB exchange control regulations.
South African NPOs often rely on peer-to-peer fundraising to supplement grant funding, yet tracking the efficacy of these donor-acquisition campaigns remains a manual, spreadsheet-heavy burden. While PayFast handles the ZAR transaction processing and ensures compliance with South African banking standards, it lacks the referral attribution logic needed to incentivize volunteer fundraisers. By using middleware like Zapier to bridge PayFast and Rewardful, NPOs can automate the commission tracking of donor referrals, effectively turning supporters into brand ambassadors. This data flow captures the unique referral ID from Rewardful and maps it against successful PayFast transactions, allowing your team to accurately attribute donor acquisition costs. By automating this attribution, you eliminate the manual reconciliation of referral rewards, freeing up administrative capacity to focus on DSD compliance reporting and Section 18A tax certificate issuance rather than tracking donor lead sources.

How to add PayFast to Rewardful
- 1
1. Create a Rewardful account and configure your campaign settings to define the "bounty" or recognition structure for your volunteer fundraisers. Ensure your terms reflect South African tax law, noting that individual referral rewards may have implications for the recipient's SARS tax obligations.
- 2
Set up a Zapier account to act as the middleware, as no native integration exists between PayFast and Rewardful. This bridge is necessary to translate PayFast’s transaction data into a format that Rewardful’s API can ingest for attribution.
- 3
Configure your PayFast account to enable Instant Payment Notification (IPN) and ensure your website’s donation form captures the Rewardful referral cookie. This cookie must be stored in your local database or session storage to ensure the referral ID is passed to the payment gateway.
- 4
Create a "New Successful Transaction" trigger in Zapier linked to your PayFast account. Filter this trigger to only process transactions marked as "Complete" to ensure you are not tracking failed or pending ZAR payments.
- 5
Map the PayFast transaction data to the Rewardful "Create Referral" action within Zapier. You must specifically map the transaction amount and the unique referral ID captured during the donor’s checkout process to ensure the commission is correctly attributed.
- 6
Implement a data-scrubbing step in your middleware to ensure no sensitive donor information—such as physical addresses or ID numbers—is passed to Rewardful, maintaining strict compliance with POPIA. Only the transaction value and the referral identifier should be transmitted to the affiliate platform.
- 7
Test the workflow by performing a live ZAR transaction through your PayFast sandbox or a low-value donation. Verify that the referral appears in the Rewardful dashboard with the correct commission amount before rolling out the program to your donor base.
- 8
Establish a monthly reconciliation process to verify that Rewardful’s referral data matches your bank statements and SARS-compliant accounting records. This ensures that your donor acquisition costs remain transparent for your annual NPO audit and DSD reporting requirements.
