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 struggle to reconcile donor management with the rigorous administrative demands of the Department of Social Development and SARS. By connecting PayFast to Kit, your organisation can automate the manual data entry that currently consumes 30% of your administrative capacity. When a donor completes a transaction in ZAR, this workflow triggers an immediate, personalised email sequence in Kit, simultaneously tagging the donor for specific grant reporting segments. This automation ensures that donor communication remains consistent while capturing the precise metadata required for Section 18A tax certificate issuance. By offloading these repetitive tasks to a middleware bridge, your team can focus on programme delivery rather than reconciling spreadsheets. This setup ensures full compliance with POPIA by centralising donor data securely, while providing the audit trail necessary for foreign funding transparency and local regulatory reporting.

How to add PayFast to Kit (ConvertKit)
- 1
1. Create a Zapier or Make account to serve as the essential middleware, as PayFast’s Instant Payment Notification (IPN) cannot communicate directly with Kit’s API. You will use this platform to intercept the raw transaction payload from PayFast and format it for Kit’s subscriber fields.
- 2
Log in to your PayFast dashboard and navigate to the 'Integrations' tab to enable the IPN (Instant Payment Notification) feature. Set the 'IPN URL' to the unique webhook address provided by your Zapier or Make project, ensuring that PayFast sends real-time transaction data to your bridge.
- 3
In Kit, create custom fields for 'Total Donated', 'Last Donation Date', and 'Section 18A Status' to ensure you can track cumulative giving for SARS compliance. These fields will act as the destination for the data variables parsed from the PayFast transaction payload.
- 4
Configure your Zapier or Make trigger to listen for the 'Payment Successful' event from PayFast. Map the incoming variables—specifically the donor’s email, name, and the ZAR amount—into the corresponding custom fields you created within your Kit account.
- 5
Add a filter step in your middleware to ensure only successful, completed transactions trigger the automation. This prevents failed or pending payments from incorrectly updating your donor records or triggering premature tax certificate communications.
- 6
Set up an action in your middleware to 'Add or Update a Subscriber' in Kit using the donor’s email address. Ensure the mapping includes the donor's name and the specific donation amount, which allows you to segment your audience based on their contribution levels for future grant reporting.
- 7
Create a specific 'Donor Thank You' sequence in Kit that uses liquid tags to pull the donation amount and date directly into the email body. This provides the donor with an immediate, professional acknowledgment that serves as the foundation for their Section 18A tax certificate record.
- 8
Conduct a test transaction in PayFast using the 'Sandbox' mode to verify that the data flows correctly into Kit’s subscriber profile. Confirm that the donor is correctly tagged and that the custom fields reflect the ZAR amount, ensuring your POPIA-compliant database is ready for audit-ready reporting.

Frequently asked questions
Is PayFast compatible with Kit (ConvertKit)?
Yes. PayFast and Kit (ConvertKit) can be connected via their APIs or through automation tools like Zapier. This guide covers the exact process for South African non-profit & ngo businesses.
How long does the setup take?
Most businesses complete the initial setup in 1–3 hours. If you already have active accounts on both platforms, you can have a basic automation running in under an hour.
Do I need a developer?
Not for basic Zapier-based integrations. Custom API integrations will need development support. Melamu Tech Ventures builds these — get in touch if you need a tailored solution.
