Zoho CRM API Update records charset

Zoho CRM API Update records charset

Hi,

I am trying to automatically update my phone field in zoho CRM using the API. But I can not get the whole phone number updated.

I want to add my phone number with the following format [country code][area code][phonenumber] for example

+31 1 234567890

But when I update a record the + char and spaces are not updated so the phonenumber in zoho becomes

311234567890

Can you maybe tell me which charset is used and if it possible to send these kind of characters to a phone field

Kind regards
Joost Verheijen
