Frequently Asked Questions

The WhatsApp Business Platform (a.k.a. WhatsApp Business API solution) gives medium to large businesses the ability to connect with customers at scale, offering advanced features like automated messaging, chatbots, interactive messages, and seamless integration with business systems.

To apply for the WhatsApp Business API through SleekFlow, you must be an admin of your Meta Business account and have enabled two-factor authentication on your Facebook personal account for security. Please also prepare business registration documents or bank/service bills that confirm your company details during the sign-up process.

A blue tick verified badge on WhatsApp indicates that Meta has verified the business based on its activity and the documents provided. The blue tick signifies that the business is official, enhancing its brand image and reducing the risk of fraud. To qualify, businesses must: a. Have a verified Business Manager with a display name aligned with the client’s branding (it cannot belong to another company). b. Maintain a ‘high’ quality rating for the number when applying. c. Adhere to WhatsApp's policies, particularly the Commerce Policy. d. Have a verified Facebook Business Manager. e. Be a notable and reputed brand as determined by WhatsApp, such as having a high-quality business website, sufficient media exposure (as determined by WhatsApp), and completing the Business Verification process.

No, the WhatsApp Business API is not free. Unlike the WhatsApp Business App, which is free, the API has per-template-message pricing that varies by country. However, SleekFlow offers competitive pricing as a WhatsApp Business Solution Provider (BSP), often providing the best rates in the market.
