How banking and financial services can use WhatsApp Business API

When it comes to asking others to handle their hard-earned money, consumers often have high expectations of customer service. Issues, like having extra charges on a credit card or being unable to transfer money to an intended recipient, can cause great inconveniences to customers that could potentially drive them away for good. In the fintech industry, the level of promptness, security, and personalisation significantly impact customer experiences. 

Let’s dive deeper to see how WhatsApp Business API fills the gaps in these decision-making factors. 

Data security and protection

WhatsApp end to end encrpytion

As conversations between finance companies and their customers often pertain to confidential information, WhatsApp’s end-to-end encryption (E2EE) ensures that the sender and receiver are the only ones who can read or listen or see what is sent. Even though WhatsApp is the intermediary server that passes the message along, the message’s encryption makes it indecipherable to WhatsApp itself. 

WhatsApp’s E2EE also prevents encrypted messages from data tampering, thus guaranteeing that any sensitive information is protected during transit. Furthermore, WhatsApp’s Business API is GDPR-compliant, the EU’s new data protection law. 

Highly personalised customer experience

Google’s survey shows that 68% of respondents are more likely to buy from a business that offers convenient communications, implying that mobile-friendly, instant messaging could be the optimal way for businesses to reach their consumers. 

As customers increasingly rely on social messaging channels to transact and interact on a daily basis, businesses in the finance sector are taking advantage of platforms, such as WhatsApp Business API, Skype/Zoom, and voice assistants, to enhance customer experience. These channels allow financial services to engage with customers more intuitively, creating golden opportunities to transform digital touch points into revenue sources.
