Chat API and WhatsApp Business API: Comparative Analysis, Advantages and Disadvantages

A transparent comparison of the official API and our own API.
Published: 30 November 2020

The year 2020 is slowly, but surely coming to an end and it’s time to review what we have achieved. In particular, we would like to compare official ways of using WhatsApp with unofficial solutions and see what has changed here by the end of 2020. The article will be interesting for those who want to learn about the difference between WhatsApp business App, WhatsApp business API, and other WhatsApp APIs, and evaluate the risks and challenges of each of the tools.

A Bit of History

Initially, WhatsApp, unlike, say, Telegram, kept their API closed, which was why developers could not offer programming solutions for WhatsApp — there were neither integrations with CRM or ERP systems nor popular chatbots. In those misty times, programmers created or looked for unofficial gateways that provided access to WhatsApp API. Those solutions can still be found on Github. The problem with using those libraries is that, from time to time, WhatsApp issues updates which is why the solutions become obsolete and phone numbers get banned almost immediately.

As time went by, businesses began to feel the need for WhatsApp more and more. The messaging format is very convenient for clients and, with its 1.7 billion users, WhatsApp has become the most popular messenger. We asked the opinion of many marketing specialists as to why WhatsApp was so popular, and they all gave about the same answer: “I’m not sure why but people like it.” It seems that WhatsApp has already gained a critical mass of users that will help to keep it going.

Anyway, where there is demand, there will be supply. At the moment, we see a rise in companies who offer their APIs for WhatsApp. Most of them use the WhatsApp WEB protocol (we will expand on protocols below). Naturally, Chat API offers a WhatsApp API, too. We developed our solution in 2015 when we worked at integration with amoCRM. We have always positioned it as a tool for businesses and software developers. We should note, however, that we are against spamming or any other malicious activity.

And, of course, we are against spam and other abuses.

Warning!
We urge our customers not to send unsolicited messages or make mass marketing mailings. Otherwise your account may be blocked by the WhatsApp anti-spam system! Contact our technical support for more detailed recommendations.

In 2017, WhatsApp released its official API. At first, during the test period, the API was only available to a few major companies. Since then, the number of organizations that have access to the WhatsApp official API has increased. To get the access, businesses must make an agreement with WhatsApp’s official partners and follow a set of WhatsApp’s current regulations. The latter imply a lot of limitations that you can find listed in the table below. To see the list of current WhatsApp’s official partners, go to https://www.facebook.com/business/partner-directory/search?solution_type=messaging. This information is important, as there has been a rise in companies that mislead their clients into thinking that they are WhatsApp’s official partners.

Okay. So, would it be right to use the WhatsApp official API?

The answer to this question is not as obvious as it may seem. The first thing you should ask yourself is: what do you need the API for? After all, both options have their upsides and downsides.

The first seemingly obvious upside of WhatsApp API is its “officialness” and safety. However, because of some substantial limitations, not every company can benefit from them. The list of limitations is presented below:

  1. The price. The monthly payment for using the official WhatsApp API varies from a few hundred dollars to thousands of dollars. The price does not include the connecting cost and the cost of individual WhatsApp messages. Besides, since the rates are managed by WhatsApp itself, it is not always possible for agents to tailor them to your individual needs. To learn more about the prices, go to the developer’s official website: https://developers.facebook.com/docs/whatsapp/pricing#usd

  2. To connect to the official API, businesses must have a message turnover of at least 15,000 per month which may be too many for some companies.

  3. WhatsApp does not partner with every business. For example, while finances and real estate are interesting for it, companies selling vitamins or drugs do not get approved by the messenger.

  4. Dealing with WhatsApp’s official representatives to obtain their “white” API is an extremely energy-consuming procedure. Gathering and putting in order various documents, going through verification processes, creating and approving of templates — all of this may take a lot of your time and still result in denying you the access. Yes, unfortunately, this scenario is probable, too.

Okay, but it’s still better than to be banned by WhatsApp!

It is true that to have a work phone number banned is every company’s nightmare. No one would like to find themselves in a situation like this. According to WhatsApp’s statistics, every month, the messenger bans around 2,000,000 users for violating their policy.

Of course, this does not mean that unofficial APIs do not care about their customers. For example, in the case of our Chat API, we protect our clients by offering them individual IPs, safe authorization, and a system of artificial guards, such as a messaging queue to prevent bulk messaging and escape a ban. There are also systems that allow for emulating phones on a computer so that your activity would not depend on a physical device. Of course, these measures will not help if users ignore WhatsApp’s rules and spam their clients. Even with the official API, you can still be banned for violating WhatsApp’s policy. But if you combine all the safety tools offered by Chat API with an intelligent use of the service, your phone number will be absolutely safe.

Incidentally..
The article does not list all the ways we take care of the plug-in numbers. Let's leave some secret "ingredients" for our competitors. By the way, "Secure Authorization" is our unique development. We will tell you more about it separately.

Now that we have covered the most vital points, it is time to move on to the most interesting part, that is, pure analytics, and compare both ways of using WhatsApp.
