Also in 1392 he began his diplomatic career as a Polish envoy to the Grand Master of the Teutonic Order Konrad von Wallenrode. In 1397 he became the chancellor of Queen Jadwiga of Poland, and a year later (in 1398) the Włocławek Chapter wanted to him to appointed as a bishop, but Andrzej himself abandoned the title in favor of Mikołaj Kurowski, who was supported by the Polish King. Before 1402, Łaskarz became a canon of Płock, and in 1405 he was the chaplain of the German King Ruprecht Wittelsbach. In 1409 he became a papal collector in Poland and also took part, together with his relatives, the Poznań bishop Piotr Wysz Radoliński, in the Council of Pisa and pilgrimage to the Holy Land. In 1411, together with Jakub Śledz, he visited Antipope John XXIII, complaining to him about the Teutonic Knights breaking the First Peace of Toruń.

In the meantime, from 1412 to 1414 on behalf of Władysław II Jagiełło he appeared as a prosecutor in the trial between Poland and the Teutonic Order and then went as a member of the official Polish delegation to the Council of Constance, where he mainly participated in the work of the commission for faith and in the trials between Poland and the Teutonic Knights. He also became known there as a supporter of church reform and conciliarist. In 1419 he was in the procession of the king during his congress with the emperor in Nowy Sącz, and in 1420 he was in the legation to the Imperial Diet, which took place in Wrocław, during which the emperor considered Polish-Teutonic disputes. In the same year he took part in a synod called by Mikołaj Trąb to Wieluń. In 1422, he again took part in the trial with the Teutonic Knights, appearing as a witness this time, and in 1423 he took part in the Council in Pavia.
