I have created a new customer using the API
http://{{doman_name}}/index.php/rest/V1/customers
When i can the login API, a token is returning .It means the customer is active.
http://{{doman_name}}/index.php/rest/V1/integration/customer/token
But the problem is,i cant see the customer in admin dashboard.
What is the problem?
just check the customer_entity table in magento database.if u can't find any data there, then customer is not created succussfully or refresh cache once(actually its not problem with cache but try)
or
go to magento root directory with root privileges
php bin/magento indexer:reindex
