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 face the dual pressure of maintaining strict SARS Section 18A compliance while managing donor relationships with limited administrative capacity. By connecting PayFast to CallHippo, your organisation can automate the communication loop that follows every ZAR donation, ensuring that donor data flows directly into your communication hub. Instead of manually updating spreadsheets for grant reporting or DSD compliance, this integration triggers automated WhatsApp acknowledgments and call logs the moment a payment clears. This workflow eliminates the 30% of administrative time typically lost to manual data entry, allowing your team to focus on programme delivery rather than reconciliation. By centralising donor interactions within CallHippo while securing financial transactions through PayFast, you maintain a POPIA-compliant audit trail that simplifies your annual reporting requirements and strengthens transparency for foreign funders and local stakeholders alike.

How to add PayFast to CallHippo
- 1
1. Log into your PayFast merchant dashboard and navigate to 'Settings' > 'Integration' to locate your Merchant ID, Merchant Key, and Passphrase. You will need these credentials to authenticate the connection between your payment gateway and your chosen middleware platform.
- 2
Create an account on a middleware service like Make or Zapier, which acts as the necessary bridge to facilitate data transfer between PayFast and CallHippo. This middleware is required because neither platform offers a native, direct integration for this specific data flow.
- 3
Set up a 'Webhook' trigger in your middleware platform and copy the provided URL to your clipboard. Paste this URL into the 'Instant Payment Notification (IPN)' field within your PayFast 'Settings' > 'Integration' tab to ensure real-time transaction data is sent to the middleware.
- 4
Configure your middleware to parse the incoming PayFast IPN data, specifically mapping the donor’s contact information, the ZAR transaction amount, and the payment status. Ensure that all data handling complies with POPIA regulations by filtering only the necessary fields required for donor communication.
- 5
Establish a connection to the CallHippo API within your middleware using your CallHippo API Key found in your account settings. This connection allows the middleware to push data into your CallHippo dashboard, effectively bridging the gap between financial receipts and communication logs.
- 6
Ensure your CallHippo account is upgraded to the WhatsApp Business API tier, as standard CallHippo accounts cannot trigger automated WhatsApp templates via external webhooks. This specific service tier is a prerequisite for sending automated donation receipts or thank-you messages.
- 7
Create a 'POST' request action in your middleware that targets the CallHippo WhatsApp API endpoint to trigger your pre-approved message template. Map the donor’s phone number and name from the PayFast data to ensure the communication is personalised and professional.
- 8
Conduct a test transaction using the PayFast 'Sandbox' mode to verify that the payment triggers the middleware, which subsequently pushes the data to CallHippo. Confirm that the automated WhatsApp message is received and that the transaction is correctly logged in your CallHippo activity feed for future audit and reporting purposes.
