Sonar · Last updated 12 November 2026
These terms apply to a business we've made a Sonar partner (the partner), on top of Sonar's Terms of Service and Operator Agreement, which the partner has already accepted for its own account. The partner accepts them when its owner makes the partner key. A property is a business the partner adds for one of its customers through the partner API.
For each property with a WhatsApp number connected, the partner pays Sonar that property's plan at Sonar's normal list price each month, as part of the partner's own renewal, plus what the property used past its plan's included messages. A property is paid for from the day its number connects: the rest of the partner's billing period is charged then, and a move to a dearer plan charges the difference for the rest of the period. There is no free period. If the partner's renewal isn't paid, its account and its properties move to the Free plan. Meta charges each property's own payment method for its template messages; Sonar doesn't collect those.
The partner sets its own prices for its customers and bills them itself. Sonar doesn't bill a property, show it Sonar's prices, or contact it about billing.
Each customer is the responsible party for its contacts' personal information under POPIA. The partner processes it for the customer, and Sonar processes it for the partner as a sub-operator, on the terms of Sonar's Operator Agreement. The partner must have a written agreement with each customer that allows this, including Sonar as its sub-operator, and must pass Sonar's Operator Agreement obligations on to the customer where they apply to it. The partner must tell Sonar without delay of any request from a data subject or a customer to see, correct or delete information held in Sonar.
The partner and its customers must follow Meta's WhatsApp Business Messaging Policy and Commerce Policy, including getting people's opt-in before messaging them, and Sonar's acceptable use rules in its Terms. Sonar may pause a property or the partner's access if a number is used for spam, scams or anything else those rules forbid, or if Meta asks us to.
The partner keeps its partner key and its properties' API keys secret, stores them securely, and replaces any key that may have leaked (the partner API can replace a number's key at once). The partner is responsible for what is sent with its keys.
A partner can add up to 100 properties unless we agree a higher limit. The partner gives its customers first-line support; Sonar supports the partner. A customer who contacts Sonar about billing or their account is referred to the partner.
The partner can remove a property at any time through the partner API: its data is deleted 24 hours later, as in Sonar's privacy notice, and its usage so far is billed. If partner access ends, the partner and Sonar agree within 30 days whether each property moves to its own Sonar account or is removed; otherwise it is removed. Either side can end partner access with 30 days' written notice, or at once for a serious breach.
