Question

I am trying to insert a record zoho however i am getting the following error :
Uncaught ParseError: syntax error, unexpected ''https://www.zohoapis.com/crm/' (T_CONSTANT_ENCAPSED_STRING) in wp-content/themes/tsahiasa/functions.php:486

I tried using both " (double quotes) and ' (single quotes) however i am still getting the error. Below is my code snippet and the line with error :
