The custom tag endpoints are a set of endpoints that allow you to manage custom tags and associate them with specific resources. Custom tags are labels or categories that you can assign to different entities, such as user accounts or campaigns, to organize and group them based on certain criteria.

Resource Type and Resource ID: The resource type and resource ID are used to uniquely identify a specific resource.

• Resource Type: The resource type is a way to categorize different types of resources in your application. It helps distinguish between different entities that can have custom tags assigned to them. For example, you might have resource types such as "account" for user accounts and "campaign" for marketing campaigns.
• Resource ID: The resource ID is a unique identifier for a specific resource within a resource type. It allows you to reference a particular resource when assigning or retrieving custom tags. For example, if you have a user account with an email address "johndoe@instantly.ai", the email address would be the resource ID for the "account" resource type.
