WhatsApp (officially WhatsApp Messenger) is an instant messaging (IM) and voice-over-IP (VoIP) service owned by technology conglomerate Meta.[14] It allows users to send text, voice messages and video messages,[15] make voice and video calls, and share images, documents, user locations, and other content.[16][17] WhatsApp's client application runs on mobile devices, and can be accessed from computers.[18] The service requires a cellular mobile telephone number to sign up.[19] In January 2018, WhatsApp released a standalone business app called WhatsApp Business which can communicate with the standard WhatsApp client.[20][21]

Although Acton was working on another startup idea, he decided to join the company.[27] In October 2009, Acton persuaded five former friends at Yahoo! to invest $250,000 in seed funding, and Acton became a co-founder and was given a stake. He officially joined WhatsApp on November 1.[27] Koum then hired a friend in Los Angeles, Chris Peiffer, to develop a BlackBerry version, which arrived two months later.[27] Subsequently, WhatsApp for Symbian OS was added in May 2010, and for Android OS in August 2010.[64] In 2010 Google made multiple acquisition offers for WhatsApp, which were all declined.[65]

In April 2023, the app rolled out a feature that would allow account access across multiple phones, in a shift that would make it more like competitors. Messages would still be end-to-end encrypted.[159]WhatsApp officially rolled out the Companion mode for Android users, allowing you to link up to five Android phones to a single account. Now, the feature is also made available to iOS users, allowing them to link up to four iPhones.[160]

After months at beta stage, the official first release of WhatsApp for iOS launched in November 2009. In January 2010, support for BlackBerry smartphones was added; and subsequently for Symbian OS in May 2010, and for Android OS in August 2010. In August 2011, a beta for Nokia's non-smartphone OS Series 40 was added. A month later, support for Windows Phone was added, followed by BlackBerry 10 in March 2013.[177] In April 2015, support for Samsung's Tizen OS was added.[178] The oldest device capable of running WhatsApp was the Symbian-based Nokia N95 released in March 2007, but support was later discontinued.

As of 2023[update], WhatsApp does not have an official iPad client.[189] While the majority of iPhone apps can run on the iPad in an iPhone sized window, WhatsApp was one of the very few apps to be completely unavailable on the iPad due to the "telephony" restriction. In a 2022 interview with The Verge, WhatsApp chief Will Cathcart acknowledged that "[p]eople have wanted an iPad app for a long time" and said that the team would "love to do it."[207] In September 2023, a beta version of WhatsApp was released for iPad. No official release date has been announced.[208]

WhatsApp uses a customized version of the open standard Extensible messaging and presence protocol (XMPP).[210] Upon installation, it creates a user account using the user's phone number as the username (Jabber ID: [phone number]@s.whatsapp.net).

On November 18, 2014, Open Whisper Systems announced a partnership with WhatsApp to provide end-to-end encryption by incorporating the encryption protocol used in Signal into each WhatsApp client platform.[227] Open Whisper Systems said that they had already incorporated the protocol into the latest WhatsApp client for Android, and that support for other clients, group/media messages, and key verification would be coming soon after.[228] WhatsApp confirmed the partnership to reporters, but there was no announcement or documentation about the encryption feature on the official website, and further requests for comment were declined.[229] In April 2015, German magazine Heise security used ARP spoofing to confirm that the protocol had been implemented for Android-to-Android messages, and that WhatsApp messages from or to iPhones running iOS were still not end-to-end encrypted.[230] They expressed the concern that regular WhatsApp users still could not tell the difference between end-to-end encrypted messages and regular messages.[230]

In September 2022, a critical security issue in WhatsApp's Android video call feature was reported. An integer overflow bug allowed a malicious user to take full control of the victim's application once a video call between two WhatsApp users was established. The issue was patched on the day it was officially reported.[285]

The information commissioner has said that the use of WhatsApp posed risks for transparency since members of Parliament, government ministers, and officials who wished to avoid scrutiny might use WhatsApp despite there being official channels.[287] Transparency campaigners have challenged the practice in court.[288]

Notably, during the COVID-19 pandemic, the UK government routinely made use of WhatsApp to make decisions on managing the crisis, including on personal rather than government issued devices. When the official inquiry into the pandemic began seeking evidence in May 2023 this presented issues for its ability to gather the material it sought. A personal device of the former Prime Minister, Boris Johnson, had been compromised by a security breach and it was claimed it could not be switched on in order to recover messages.[289] Further, the Cabinet Office had claimed that since many messages were not relevant to the inquiry, it only needed to hand over material it had selected as being relevant. The High Court, in a judicial review sought by the Cabinet Office, declared that all documents sought by the inquiry were to be handed over unredacted.[290]

In January 2020, a digital forensic analysis revealed that the Amazon founder Jeff Bezos received an encrypted message on WhatsApp from the official account of Saudi Arabia's Crown Prince Mohammed bin Salman. The message reportedly contained a malicious file, the receipt of which resulted in Bezos' phone being hacked. The United Nations' special rapporteur David Kaye and Agnes Callamard later confirmed that Jeff Bezos' phone was hacked through WhatsApp, as he was one of the targets of Saudi's hit list of individuals close to The Washington Post journalist Jamal Khashoggi.[301]

In August 2021, the digital rights organization Access Now reported that WhatsApp along with several other social media apps was being blocked in Zambia for the duration of the general election. The organization reported a massive drop-off in traffic for the blocked services, though the country's government made no official statements about the block.[340]

I've applied to gain access to the WhatsApp Business API but haven't received any response from them so far. I've waited over a month and have kind of given up any hope of receiving an approval. I had a look at some of the unofficial APIs (such as chat-api, wassenger, etc.) that claim to provide services very similar to the official business API.

So my question to you is if there are any disadvantages or legal ramifications to using one of these unofficial services, and if not, which ones I should be considering as potential candidates to connect my chatbot to.

This can be your CRM or email marketing platform, like Brevo, an official Meta Business Partner that offers WhatsApp campaigns. Essentially, it makes WhatsApp usable in conjunction with other marketing tools. For example, using a live chat platform to manage communication from Facebook Messenger and WhatsApp in one place.

I installed whatsapp plus year ago or so. I entered several groups did some conversions. a month ago whenever I press or go to the app it showed me you can't use it anymore after the 1st of April and I have to revert back to the official, but i could get in yet after 1st of April I'm only stuck at that page.

1-I had edited the date so it worked and did a backup and refused to restore it as normal

2-so, I got the whatsapp folder and uninstalled the whatsapp gold

3-took the files from the \abo3rabBackup\databases and put them in /data/data/com.whatsapp/databases

and key from \abo3rabBackup\files to /data/data/com.whatsapp/files

keystore.xml from \abo3rabBackup\shared_prefs to /data/data/com.whatsapp/shared_prefs

of the official whatsapp newly installed because they seemed from the system I assumed that because the msgstore.db was not encrypted

4-and whatsapp asked me to set it up once again and I could see all the messages of people and groups again as normal and make a back up although is shows I'm not a member of all these groups anymore

Based on AudienceProject findings, 50% of American WhatsApp users access the messenger service daily. An additional 28% use WhatsApp at least once a week, which brings the total to 78% of American WhatsApp users accessing the app weekly.

With the increase in the use of the internet comes social connectivity among people. Its Introduction in 2009 made it an extremely huge success, as now the connectivity amongst the person or group of people you admire is as easy as having a piece of cake. Whatsapp as we all know is absolutely a boon for our society. It is the easiest way to get connected with anyone, as it offers an extremely fast bridge of communication. Along with the TEXT MESSAGES, one can also have a VOICE CALL known as WhatsApp call, which is again very clear and uses a very small amount of internet. A call of 30 minutes would approximately use 5.5 MB of internet.

The revolution of internet and specifically mobile internet has occurred at a blinding pace over the last decade. With the advent of smart phones, the hand held device has become much more than a medium of voice calling. Healthcare has been catching up with the digital revolution in the form of Hospital Information System and Laboratory Information System. However, the advent of instant messaging services, which are abundantly used by the youth, can be used to improve communication and coordination among the various stake holders in the healthcare sector. We have tried to look at the impact of using the WhatsApp messenger service in the laboratory management system, by forming multiple groups of the various subsections of the laboratory. A total of 35 members used this service for a period of 3 months and their response was taken on a scale of 1 to 10. There was significant improvement in the communication in the form of sharing photographic evidence, information about accidents, critical alerts, duty rosters, academic activities and getting directives from seniors. There was also some increase in the load of adding information to the application and disturbance in the routine activities; but the benefits far outweighed the minor hassles. We thereby suggest and foresee another communication revolution which will change the way information is shared in a healthcare sector, with hospital specific dedicated apps. ff782bc1db
