What is Activity API ??

Hello @malikmuzammal256, Apologies for the delay in getting back to you on this thread. The activity API allows you and your agents to record activities from an external application or system in Freshdesk's contact timeline. Activities published using this API would show up on the contact timeline giving your agents a complete view of the customer’s journey. The additional details would help you to avoid redundant questions with your customers and provide top-notch customer service. 

You can find more details on how you can use the API here. If you have any further queries, you can write to support@freshdesk.com and we’d love to help you!
