WhatsApp via QR Code lets you connect without the official API, using WhatsApp Web to build bots. This approach gives you the flexibility of keeping WhatsApp on your mobile device, connecting through a QR Code as if you were opening WhatsApp Web. One of its advantages is the absence of per-message costs, which are typical of the official API. On the other hand, because it does not use the official API, there are risks tied to improper use of WhatsApp policies, which may result in losing access to the number.
To avoid blocks, it is crucial to "warm up" the SIM, that is, to keep the number active and engaged before starting to send automated messages. You can achieve this through frequent interactions, such as replying to messages or taking part in groups, showing regular activity. Strategies such as advertising products at attractive prices can generate a high volume of messages, helping to warm up the SIM.
When sending through an unofficial API, it is important to personalise your messages to avoid being perceived as spam by recipients. Besides that, the number of reports and blocks from users may lead to the number being banned. Offering an opt-out option in the messages you send can reduce the risk of blocks.
With WhatsApp via QR Code you can send and receive a wide range of content, including text, images, videos, documents and locations. Despite some limitations, such as message buttons not being compatible with unofficial WhatsApp, it is possible to make quick calls, manage product catalogues and check WhatsApp availability for specific numbers. Group management is possible, although NicoChat is optimised for one-to-one conversations.
There are three ways to connect WhatsApp via QR Code to NicoChat:
NicoZap is the provider built by NicoChat itself: it connects by QR Code or pairing code, with no VPS and no external subscription. It is the simplest path, and anyone already using another provider can migrate while keeping the channel, the flows and the contacts.
Z-API offers a robust API for connecting to WhatsApp, but it does not include a Flow Builder. Subscribing to Z-API provides a stable and simplified integration, with a 10% discount available through NicoChat. Get the discount here
Evolution API stands out for being self-hosted and open source, allowing a direct deployment on your own servers. Although it offers a more economical solution, its setup is more complex than Z-API.
