2-Way Chat Using Tall Bob APIs

Modified on Mon, 2 Sep at 2:41 PM


Tall Bob offers a specialised endpoint for managing Two Way Chat at scale, which ensures that multiple conversations between businesses and clients are not confused in a single conversation thread. Some businesses that require managing high volumes of two-way communication with their customers are:

  • Real Estate Agencies
  • Delivery Companies
  • Food Delivery Services


This is achieved through the use of dedicated long codes and a 2-part key that manages the long code when sending messages. Businesses need only specify a reference in the payload and the recipient's phone number, after which the platform automatically manages the entire process of assigning a long code from a pool of dedicated long codes attached to the business's account. The Tall Bob system ensures that conversations remain distinct and clear, without the risk of confusion or miscommunication.

Please contact your Account Manager to set up your chat longcode before using the endpoint

Scenario: Vaccination follow-up

  • A mother and three children receive vaccinations at a doctor's office
  • The vaccination program includes a follow-up SMS to check for any side effects
  • The mother's mobile number is used as the contact number for all four patients
  • If a dedicated long code is used for 2-way messaging, the mother will receive a follow-up message from the same long code for all four patients, asking if any side effects were experienced
