docs. robokassa. ru is the technical documentation of the Robokassa payment system. The resource was created for developers and website owners who need to understand the mechanisms for accepting payments. There is no marketing fluff here, only dry instructions for integration.
The site offers two main ways to connect payment. The first is for those who use popular engines like Tilda, WordPress or 1C-Bitrix. The second is for self-written projects and native mobile applications that require working with APIs.
The documentation is structured so that the user can quickly find the desired section. The main blocks include:
One of the key features is the presence of a test mode. This allows you to test the integration without complex settings and real money. The system supports cards, SBP and electronic payment methods.
The Frequent Errors (FAQ) section contains specific problems that developers encounter. For example, a signature error often occurs due to the incorrect order of parameters or the use of an incorrect secret password. They also pay attention to the accuracy of the amounts: they must be transmitted with two decimal places. Another common problem is incorrect encoding; The recommendation here is to use UTF-8 for all requests.
If the callback does not arrive, the system advises checking the availability of ResultURL from the Internet. It is important that the server returns the OK string along with the order number.
For contact, the email address is support@robokassa. ru. If you are already a client, it is better to use the ticket system in your personal account. When contacting, be sure to indicate MerchantLogin, payment number and time of transaction.
You need to check the order in which the parameters are passed and make sure that the correct secret password is used.
The amount should be transmitted accurate to two decimal places. Any deviations may result in incorrect processing.
UTF-8 must be used for all requests and responses.
First make sure that the ResultURL address is accessible from the Internet. Then check if the script returns an OK response.
