Hello @Tatiana129,
Do you mean that you want to change the way Airbnb pays you?
If Western Union is now the only way Airbnb Pays you then you'll have to add the new method first.
When the new method is ready you must make it the default method. Then you'll be able to delete the Western Union method if you want to.
On a computer, click on your profile photo and then on "Account settings".
Then click on "Payout preferences".
Now click on "Add a payout method". Fill in the address that the finance company has for you and click on "Next"
If international wire is available as an option it will appear. If not then it won't appear as an option.
If it's available as an option complete any other details needed.
After a few days the status of the account should change to "Ready" just like it is now for your Western Union account.
When that happens click on the "Options" button for the new account and set it as default if you want to get paid to it.
You can then click on the "Options" button for Western Union to remove it if you want to.
Steve.
