As per the requirement there should be only one address for the contact i.e., either BILLING or SHIPPING or OTHER. In the first instance if user adds BILLING address then if he wants to change it to SHIPPING, BILLING address should be erased and SHIPPING address should be updated.
I am using update contact API(PATCH) method to update the address but the second value in postal code is not getting updated to empty string.
For example if I am having postal code as 12345-6789 I am able to erase 12345 from Keap but 6789 is not getting erased using the update API.
Could you please let me know if there is a way to erase the entire postal code using the API.
Thanks in Advance
