I will order a simple integration of the REGON database through the API provided by the authority. The integration is to be only in terms of REGON Database <-> Integromat/Make (SOAP protocol). Ultimately, after sending the TIN, the full company information is to be returned in json or xml format. It is enough that the retrieved data will be waiting in the Integromat object (no need to integrate further). The execution of the order can only consist of giving instructions on how to configure Integromat, but it must work. Instructions to the API: https://api.stat.gov.pl/Home/RegonApi (I already have the key provided).
