Definition
WebService Method is a Salesforce development feature that provides developers with the ability to create custom solutions on the Lightning Platform. It supports building robust, scalable applications that integrate with Salesforce's data and security model.
Real-World Example
a Salesforce developer at CodeBridge recently implemented WebService Method to create a robust integration between Salesforce and an external system. Using WebService Method, the developer builds an efficient solution that syncs data in near real-time, handles error scenarios gracefully, and includes detailed logging for troubleshooting.
Why WebService Method Matters
A WebService Method in Salesforce is an Apex method declared with the webService keyword that exposes custom logic as a SOAP-based web service endpoint. It allows external systems to call specific Salesforce business logic over the network, solving the problem of needing to invoke custom processing from outside the Salesforce UI. WebService Methods must be static, defined in global classes, and can accept and return primitive types, sObjects, or lists, making them a targeted way to share specific operations with integration partners.
As integration requirements grow, WebService Methods provide a controlled way to expose only the specific operations external systems need, rather than granting broad API access. However, they come with limitations: they cannot be used in triggers, must be in global classes (which cannot be easily deleted from production), and only support SOAP protocol. Organizations that create too many WebService Methods without documentation or versioning often face a tangled integration landscape. Modern best practice recommends considering REST-based Apex services annotated with @RestResource for new development due to wider client compatibility and lighter payloads.
How Organizations Use WebService Method
- Nexus Telecom — Nexus created a WebService Method that accepts a phone number and returns the customer's account status, plan details, and last payment date. Their IVR system calls this method when customers dial in, enabling the automated phone system to provide account information without a live agent, deflecting 35% of calls.
- Sterling Logistics — Sterling exposed a WebService Method that accepts a list of shipment IDs and returns their current status and estimated delivery dates. Their customer portal built in .NET calls this method to display real-time shipment tracking, replacing a manual email-based inquiry process that took 2-4 hours per response.
- Apex Healthcare — Apex Healthcare built a WebService Method that validates insurance eligibility by accepting a policy number and patient DOB, querying related records, and returning a structured response. Their intake application calls this method during patient registration, completing eligibility checks in under 3 seconds compared to the previous 10-minute manual lookup.
