How to work with WhatsApp API via Chat API for free?

If you are a developer and you are interested in the service, but you are not yet ready to pay the full cost of an instance, then you can use our unique and free cooperation option - an account for developers.

This is our new offer, created specifically for developers, which will help you debug your solution, integrate or set up a chat bot without paying for an instance upfront. This is an ideal solution when you need to carry out your project, but it is not yet prepared enough to monetize it.


With the help of an instance for developers, you will get free access to the WhatsApp API. You will be able to get acquainted with the service, debug your solution, set up a chat bot or integrate with CRM\ERP systems. This offer is free, but the instance for developers has its own limitations:

1- The working phase of the instance is 3 hours, after which it will require a new activation to continue working. You can enable your instance yourself, through your personal account.

2 -You will be able to send and receive no more than 100 messages per day.
3 - And create no more than 3 WhatsApp dialogs.
4 - You can create no more than one instance for developers in your personal account.

These restrictions are necessary for the instance for developers to be used for their work tasks, namely, familiarization with the service, conducting testing, development and integration.
You can find out how to connect an instance for developers and explore the possibilities of this solution in more detail in our video introduction to the service:
