Simplifying Chatbot Design with No-Code Tools in Gupshup’s Journey Builder

The evolution of bot design has taken a significant leap forward with the introduction of two transformative features in Gupshup’s Journey Builder: the JSON Handler Node and the Expression Library. Together, these tools empower bot designers to create dynamic, functional, and user-centric conversational experiences without writing a single line of code.

With the rapid advancement of AI and the increasing demand for real-time, contextual interactions, businesses need the ability to deploy interactive campaigns, connect with CRMs, and enable agentic AI capabilities—all through conversational interfaces. Gupshup’s Journey Builder rises to this challenge, offering a low-code/no-code environment that helps product, marketing, and CX teams bring ideas to life without engineering dependencies.

JSON Handler Node: Intuitive Data Mapping

Working with APIs and parsing complex JSON responses has traditionally required developer support. The JSON Handler Node changes that narrative. This no-code action node allows bot designers to seamlessly parse JSON responses from APIs and map them to variables directly within the Journey Builder Canvas.

This feature is invaluable for use cases like:

• Fetching user details from client APIs or CRMs
• Fetching lead or order details from external systems
• Connecting loyalty or rewards systems into chat interfaces

Whether you’re handling nested JSON structures or extracting specific attribute values, the intuitive editor simplifies the entire process. With support for up to 10 mappings per node, the JSON Handler brings clarity and speed to data handling, enabling designers to transform external API responses into usable bot variables quickly.

Expression Library: Power of Excel, Now in Bot Design

The Expression Library is another game-changing addition. Think of it as Excel for bot design: over 180 pre-built expressions that allow data transformation and logic building without any coding. From string manipulations and arithmetic operations to date formatting and conditional logic, bot designers can now handle complex data operations with ease.

For example:

• Formatting names or numbers for better UX
• Performing on-the-fly calculations for offers or eligibility
• Converting and comparing dates for time-bound campaigns

Campaign Managers & Bot Designers can simply select or compose an expression in the Modify Variable node, test it within the Canvas, and deploy it in seconds. This means bot journeys that once required custom code are now accessible to anyone familiar with simple formula-like expressions.

Why It Matters

These additions mark a major shift towards democratizing bot development. For simple to medium complexity use cases, bot designers no longer need to rely on engineers for implementation. By reducing the dependency on custom code and making powerful data operations accessible through a UI, Gupshup’s Journey Builder allows teams to:

• Rapidly prototype and deploy new use cases
• Minimize development cycles and dependency bottlenecks
• Maintain and iterate bots with agility
• Connect and orchestrate multiple third-party tools and systems effortlessly

In Conclusion

With the JSON Handler Node and Expression Library, Journey Builder becomes a truly no-code platform that empowers teams to build intelligent, context-aware bots at scale. As conversational AI becomes central to customer engagement, these innovations ensure that your teams are equipped to design smarter experiences faster and with greater independence.

Whether you’re driving lead capture, support automation, campaign personalization, or CRM orchestration, Journey Builder is your go-to platform for all Conversational CX needs.
