@Irfan.Khan
I would like to know know one more question regarding update request of WCO API.
previously i have observed that when i run postman application using put request with the individual/Organisation data, it would update the data what we sent irrespective of remaining fileds like secondary/custom (the data would remain as usual). but later on i came to notice that when I use the same PUT request i saw only the fields that were send was updated and remaining secondary/custom fields remains Null(empty). this was so surprising for me.kindly help me whether the API calls of WCO has been changed Recently?? so as to change the code accordingly.
