Comparing SOAP and GraphQL: Which One Is Right for Your Application?

When it comes to API development, choosing the right protocol is crucial for creating a robust and scalable application. SOAP and GraphQL are two popular options, each with their strengths and weaknesses. This article will compare SOAP and GraphQL, helping you decide which protocol is the best fit for your application.

What is SOAP?

SOAP (Simple Object Access Protocol) is a well-established web services protocol that has been used for many years. SOAP relies on XML for data exchange and is designed to work with a wide range of transport protocols, including HTTP and SMTP.

Pros of SOAP

  1. Mature and well-documented: SOAP has been around for a long time, and as a result, it has extensive documentation and a large community of developers.
  2. Strongly-typed: SOAP enforces strict data typing, which can help catch errors early in the development process.
  3. Support for WS- specifications*: SOAP supports a wide range of WS-* specifications, offering advanced features like security and transactions.

Cons of SOAP

  1. Verbosity: SOAP’s reliance on XML can lead to large message sizes, which may impact performance and bandwidth usage.
  2. Complexity: SOAP can be complex to learn and implement, especially when working with WS-* specifications.

What is GraphQL?

GraphQL, developed by Facebook, is a relatively new query language and runtime for APIs. It enables clients to request only the data they need, reducing the amount of over- or under-fetching of data.

Pros of GraphQL

  1. Flexibility: GraphQL allows clients to request only the data they need, resulting in smaller payloads and more efficient API calls.
  2. Strongly-typed: Like SOAP, GraphQL enforces strict data typing, which helps catch errors early.
  3. Real-time updates: With GraphQL subscriptions, clients can receive real-time updates when data changes, making it suitable for applications that require real-time functionality.

Cons of GraphQL

  1. Maturity: GraphQL is a relatively new technology, and while its community is growing rapidly, it is not as mature as SOAP.
  2. Caching: GraphQL does not have a built-in caching mechanism, which can be a challenge when trying to optimize performance.

Comparing SOAP and GraphQL: Key Factors to Consider

When deciding between SOAP and GraphQL, consider the following factors:

Data Requirements

If your application requires flexibility in data fetching, GraphQL is likely the better choice. Its ability to request only the necessary data can lead to more efficient API calls and reduced bandwidth usage.

Transport Protocol

SOAP can work with various transport protocols, whereas GraphQL is primarily designed for HTTP. If your application needs to support multiple transport protocols, SOAP might be the better option.

Real-time Functionality

If your application requires real-time updates, GraphQL’s subscription feature makes it an attractive choice. SOAP does not natively support real-time updates, so implementing them can be more complex.

Maturity and Community

SOAP has been around for much longer and has a more mature and established community. If you value stability and extensive documentation, SOAP might be the better choice.


Both SOAP and GraphQL have their advantages and disadvantages, and the right choice will depend on your application’s specific requirements. If you need a flexible and efficient API with real-time capabilities, GraphQL is likely the better choice. However, if you require a mature and well-documented protocol with support for multiple transport protocols and advanced features, SOAP may be more suitable. Remember to keep your application’s requirements in mind when making your decision, and consider factors such as data needs, transport protocols, real-time functionality, and community support to ensure the best fit for your project.
