Note: An understanding of web services is highly recommended before using this action. How and when to use a web service is beyond the scope of this article.
Method supports two types of web services: REST and SOAP. Choosing between the two is dependent on the service you are calling. The parameters for both are explained below.
REST Web Service
REST (Representational State Transfer) makes data available as resources (i.e. nouns). For example: "user", "invoice", "amount".
▶ Web service type: REST
▶ Endpoint URL: the server to communicate with
▶ HTTP Method: Choose from one of the five http methods:
- GET
- POST (Allows to send body)
- PUT
- DELETE
- PATCH (Allows to send body)
▶ Parameter name: The parameter(s) to send to the server. Value from allows you to set the values to send as a parameter. For example, if you use "Text" for Value from, you can directly type it in. You can add more than one parameter.
▶ Headers: If the web service requires a header, you can send a key and a value. Value from allows you to set the values to send as a header. You also have the option to send more than one header.
▶ Body (available for POST and PATCH): If the service requires body text, enter the value here.
SOAP Web Service
SOAP (Simple Object Access Protocol) is its own protocol with more standards. It makes data available as services (verb + noun). For example: "getUser", "payInvoice", "getAmount".
- Web service type: SOAP
- Endpoint URL: the server to communicate with
- SOAP action: function call to specify for SOAP
- Parameter name: the parameter to send to the server. Value from allows you to choose where to get the parameters. e.g. If you use "Text" for Value from, you can directly type it in.
- ⊕ Add another parameter: Select this to add another parameter.
Advanced Options
In both types of services (REST or SOAP), there are further options.
- Store web service response in an Action Result: the data returned can be placed in an action result to be parsed later.
- Test Web Service: Use this special screen to test whether or not your request to a web service is successful.
{{ Replace }} Keyword
There are times when you wish the Endpoint URL to dynamically change based on a keyword. There is a mechanism in place to change the URL by enclosing it between two curly braces: {{ }}.
In the below example, the Endpoint URL requires an account name. Note the highlighted {{AccountName}}. The curly brackets ({{ }}) indicates we want to replace this word.
Under Parameter name, we indicate the word we wish to replace, and what we want to replace it with.
In the example, we want to replace {{AccountName}} with whatever value we have stored in CompanyAccount.
If, for example, the CompanyAccount field held the value "PopAndSkate", then the Endpoint URL would resolve to:
https://api.company.io/data?name=PopAndSkate
