  The INTEGRAL satellite, in orbit since October 2002, has significantly
contributed to the study of magnetars and, thanks to its unique capabilities
for the study of transient gamma-ray phenomena, it is now playing an important
role in multimessenger astrophysics. The most recent results include the
discovery of a peculiar burst from SGR J1935+2154, which gave the first
observational evidence for the connection between magnetars and fast radio
bursts, and extensive searches for bursting activity in peculiar sources, such
as the repeating FRB 20200120E in M81 and the ultra-long period magnetar
candidate GLEAMX J162759.5--523504.3.
