Fundamental Differences Between Official and Unofficial Business API

In general, Business API suppliers have two categories. They are Meta’s officially recognized solution providers (Business Solution Providers) and unofficially recognized third-party API suppliers. 

While both provide comparable functionality, only a few recognize the unofficial API. may permanently block your account and you may lose all your customer information if your account exhibits unusual behavior. Before this, let us first distinguish between unofficial and official APIs.

Unofficial API

Meta (formerly Facebook) has restricted access to the Business API until May , and only well-known brands can use it. As a result, many small and medium-sized businesses obtain unofficial APIs in order to use the API’s extended functions. They accomplish this by obtaining data from third-party suppliers.

Merchants, however, frequently create accounts using the official API. Before they can officially open an account, they must provide various supporting documents and go through complicated procedures. Therefore, many small businesses may opt for a third-party provider that can directly obtain the API. The reason primarily is for convenience, so that they do not have to go through multiple steps.

Official API

This is a Facebook-based interface for connecting to and optimizing its functionality. Connecting to the Business API and performing business authentication are both difficult procedures. Furthermore, the official API charges mostly higher than the unofficial API. But its “officially recognized” status has undeniable advantages, allowing merchants to avoid the risk of account closures.

Potential Risks of Unofficial API 

It is easier and less expensive for small businesses to apply for the unofficial API. For the time being, most smaller businesses do not require a personalized system to meet their customer service needs. In the short term, the unofficial API’s benefits and convenience can quickly meet the needs of small businesses.

Although unofficial APIs appear to have a lower audit threshold, they pose more risks. Your customer information will become increasingly important as your company grows. Moreover, if the merchant is using an unofficial API and Meta detects suspicious account behavior, the merchant is likely to lose the account. Using unofficial APIs is illegal according to ’s terms and conditions, and sending a large number of broadcast messages, initiating conversations with non-contacts, and other suspicious activities are examples. Simultaneously, you will lose your hard-earned customer base and information.

If merchants want to keep in touch with their existing customers and retain their records, the official API is the best option. However, if you do not mind losing customer information and can always get a new number, an unofficial API may fit your business.

Official API Restrictions

Although the official API is a reliable and secure platform, eCommerce should consider the following points before upgrading their account:

Message Restriction: Before sending messages to users for the first time, the official API account must send an approved template message.

However, in some Latin American, Asian, and African locales, it is the total app of choice, giving many companies a chance to engage a broader global audience.

Employing Business as part of your messaging strategy can be a game changer—a necessary tool to help you remain competitive. We've compiled five reasons to consider using Business in your customer communications.

1. Creating superior brand connections.

Cementing great brand relationships with customers is the holy grail for most businesses. And delivers on that promise by providing businesses with a closed, personal environment in which to communicate one-on-one with their customers. With , companies create ‘Business Profiles,’ a unique, fully-branded business identity.

More importantly, your Business profile gives you the opportunity to inject your brand personality with every customer interaction. And because verifies all business accounts, your customers are assured it’s not an imposter on the other end when they opt-in to connect with you.

Because Business profiles are mandatory, your branded business identity serves as the familiar face that greets users when you message them, increasing their trust in you and their loyalty to your business. And because enables multimedia communications—think photos, documents, videos, slideshares, and more—brands have the freedom to be creative with their conversations. Moving beyond a simple text or , you can infuse your brand ethos in uniquely new ways to make even more engaging customer connections. Courtney Monroe, IDC’s Group VP of Worldwide Telecommunications Research, echoes this sentiment, proclaiming that is a “powerful channel for businesses seeking to deliver an enhanced customer experience for their customers.”

2. Connecting with customers where they already are.

When was the last time your office or home rang? Or the last time you responded to direct mail? Traditional communication channels like these—and even more recent digital ones like SMS and —are no longer solely meeting consumer demand. In fact, they’re being abandoned in favor of more convenient omnichannel solutions. Successful companies understand that to deliver exceptional customer experiences they have to fish where the fish are and be on the channels their customers prefer. In fact, a Dimensions Data study reveals that nine out of ten consumers would prefer using messaging to communicate with businesses, and, according to Nielsen, 56% would rather message customer service than speak on the .

SnapTravel is just one of the forward-thinking organizations already embracing Business. They understand the need to allow their customers to easily find and book hotel rooms on a variety of messaging channels and have recently expanded their service to include . Moving to  has allowed SnapTravel to expand globally, giving more customers the freedom to reach SnapTravel on whatever messaging app they prefer.

3. Engaging globally.

If your customer base is global, or if your customer travels globally, know this: as of early , is the number one messaging app in 104 locales.

Consider how  is used by PATH, a global health non-profit based in Seattle. PATH has been working in Zambia to support the National Malaria Elimination Center with data collection, research, and community engagement. An early adopter of messaging, PATH knew that success would require the Zambian Ministry of Health to connect with frontline health providers through a channel that was simple to use and already employed by health workers. Their use of SMS showed incredible promise, and as usage of has increased in the region, PATH is adopting its use as a business application to assist with tracking data submissions, identifying reporting patterns, improving message targeting, and ensuring more secure and private connections.

On , chat is a two-way street: businesses and customers can interact directly. Real conversations don’t ask one participant to text ‘Y’ for yes, or close an app and dial the if they want to take the conversation to the next level. Today’s customers want to reach out to businesses and have real conversations, not just respond to one-way messages directed at them. This is especially true in parts of the world where two-way interactions were not possible at all due to regulatory issues, poor quality of numbers, and connectivity issues. addresses these issues by being the first app to deliver quality, reliable two-way messaging around the globe. And while serves as a great channel for notifications like delivery alerts, purchase confirmations, and customer support, it also allows a more direct way to engage your customers and have the two-way conversations that normally take place in a physical store location or over the . Apps are increasingly used to research products and services, get reviews and consultations, make a payment process, file a complaint, or book (or reschedule) a service call—all without having to , , or even visit a brand’s website. These days, conversations like these are happening within messaging apps.

Deliveroo, an innovative online food delivery service, works with over 35,000 restaurants in 12 locales and was one of the first brands to integrate messaging to support exceptional customer experience. To transform the way their customers eat, Deliveroo knew they needed to also provide the best possible food delivery experience. To accomplish this the British-based company decided on an omnichannel approach, to be available on whichever channel their customers preferred. “We’re thrilled to now be able to offer order notifications and status updates to our customers via ,” says Deliveroo CTO Mike Hudack.

5. Messaging privately and securely.
