Engaging with Salesforce's Enhanced HTTP Callout Feature: A Deep Dive

In the Salesforce Winter ‘24 release, the introduction of enhanced HTTP Callout capabilities in Flow Builder marks a significant leap forward, especially with the inclusion of the POST method alongside PUT, PATCH, and DELETE methods. This advancement opens up a new realm of possibilities for Salesforce users, enabling seamless integration of Salesforce data with external servers without the need for complex code. This feature is not just an upgrade; it’s a transformational tool that bridges the gap between Salesforce and the vast ecosystem of web services.

The Significance and Benefits

The enhanced HTTP Callout feature in Salesforce Flow Builder is a game-changer for several reasons. Firstly, it democratizes the ability to integrate with external systems by allowing non-developers to configure and execute web service requests directly within Salesforce. This means that tasks that previously required custom Apex code can now be accomplished with a few clicks in Flow Builder.

For instance, consider a scenario where a sales agent needs to initiate a return process for a customer. With the new HTTP Callout feature, the agent can start a screen flow that sends the customer’s order data from Salesforce to an external returns management system to process the return and issue store credit, all without leaving the Salesforce interface.

Overcoming Challenges

While the benefits are clear, users may encounter challenges such as understanding the correct configuration of HTTP methods, structuring JSON payloads, and handling responses from external services. The learning curve associated with these new features can be steep for those unfamiliar with web service integrations.

Actionable Tips and Best Practices

To leverage the full potential of the enhanced HTTP Callout feature, consider the following tips:

1. Understand the Basics: Familiarize yourself with the basics of HTTP methods and their purposes. For example, use POST to create new records in an external system, PUT to update existing records, PATCH for partial updates, and DELETE to remove records.

2. Use Descriptive Fields: Take advantage of the new Description fields in Flow Builder to document each key for URL paths and query parameters. This will make your flows easier to understand and maintain.

3. Validate JSON Samples: Utilize the formatted JSON samples and in-line error messages to ensure your request and response payloads are correctly structured.
4. Organize Parameters: Keep your URL path, query parameters, and request body organized into sections for clarity and ease of configuration.
5. Automate Data Mapping: When creating a resource for the request body, let Flow Builder set the data type and Apex class automatically to reduce manual effort and errors.


The enhanced HTTP Callout feature in Salesforce Flow Builder is a powerful tool that simplifies the integration of Salesforce with external systems. By understanding its significance, overcoming potential challenges, and following best practices, Salesforce users can unlock new levels of efficiency and automation.

Our clients say

From my initial call with Spencer through project implementation with John and Evan, my experience with the SOLVD team was excellent. They were quick to understand our business needs, clear when explaining the reasoning behind proposed solutions, transparent when reporting on progress and timeline, and all around enjoyable to work with. Would highly recommend and looking forward to continue working with them in the future!

SOLVD was very straight forward with everything needed to complete the project. No surprises, no issues, and cost was aligned with the estimate. They made implementation easy and quick.

As a rule, I'm pretty stingy with my recommendations. So it's a pleasure for me to recommend Solvd as a top-flight Salesforce consultancy. Solvd recently led our company's conversion to the Lightning interface and did it on time, on budget and made it easy for me and my team. I know I'll use their services again, and am confident they can do the same for you.
