Term API Basics
You can manage terms and conditions from the Applications menu or with REST APIs. Use the /terms
endpoint from headless-admin-commerce-order to create and manage terms and conditions.
Adding a Term
Start a new Liferay DXP instance by running
docker run -it -m 8g -p 8080:8080 liferay/dxp:2024.q1.1
Sign in to Liferay at http://localhost:8080 using the email address test@liferay.com and the password test. When prompted, change the password to learn.
Once Liferay is running,
-
Download and unzip Term API Basics.
curl https://resources.learn.liferay.com/commerce/latest/en/order-management/developer-guide/liferay-a9v8.zip -O
unzip liferay-a9v8.zip
-
Four parameters are required to create terms and conditions: label, name, priority, and type.
Parameter Value Type Description/
ExampleLabel Text Enter a comma-separated list of locale/value properties: {"en_US": "Foo", "es_ES": "Bar"}
Name Text Enter a unique name for the terms and conditions item: "name": "foo"
Priority Number (double) Enter a unique numeric priority: "priority": 1.2
Type Text Specify "payment-terms"
or"delivery-terms"
:"type": "payment-terms"
Use the cURL script to add terms and conditions to your instance. On the command line, navigate to the
curl
folder. Execute theTerm_POST_ToInstance.sh
script../Term_POST_ToInstance.sh
The JSON response shows the newly added terms and conditions:
{ "actions" : { "permissions" : { "method" : "PATCH", "href" : "http://localhost:8080/o/headless-commerce-admin-order/v1.0/terms/46418" }, "get" : { "method" : "GET", "href" : "http://localhost:8080/o/headless-commerce-admin-order/v1.0/terms/46418" }, "update" : { "method" : "PATCH", "href" : "http://localhost:8080/o/headless-commerce-admin-order/v1.0/terms/46418" }, "delete" : { "method" : "DELETE", "href" : "http://localhost:8080/o/headless-commerce-admin-order/v1.0/terms/46418" } }, "active" : false, "description" : { "en_US" : "" }, "displayDate" : "2023-03-03T13:16:00Z", "externalReferenceCode" : "7fa19a0c-4c98-6c36-f1bc-5a2c4257220c", "id" : 46418, "label" : { "en_US" : "Foo" }, "name" : "foo", "priority" : 0.0, "type" : "payment-terms", "typeLocalized" : "Payment Terms", "typeSettings" : "", "workflowStatusInfo" : { "code" : 0, "label" : "approved", "label_i18n" : "Approved" } }
-
Navigate to Global Menu () → Commerce → Terms and Conditions. The newly added terms and conditions appear.
-
Alternatively, call the REST service using the Java client. Navigate into the
java
folder and compile the source files:javac -classpath .:* *.java
-
Run the
Term_POST_ToInstance
class.java -classpath .:* Term_POST_ToInstance
Examine the cURL Command
The Term_POST_ToInstance.sh
script calls the REST service with a cURL command.
curl \
"http://localhost:8080/o/headless-commerce-admin-order/v1.0/terms" \
--data-raw '
{
"label": {
"en_US": "Foo"
},
"name": "foo",
"priority": 0,
"type": "payment-terms"
}' \
--header "Content-Type: application/json" \
--request "POST" \
--user "test@liferay.com:learn"
Here are the command’s arguments:
Arguments | Description |
---|---|
-H "Content-Type: application/json" | Set the request body format to JSON. |
-X POST | Set the HTTP method to invoke at the specified endpoint. |
"http://localhost:8080/o/headless-commerce-admin-order/v1.0/terms" | Specify the REST service endpoint. |
-d "{\"label\": {\"en_US\": \"Foo\"}, \"name\": \"foo\", \"priority\": 0, \"type\": \"payment-terms\"}" | Enter the data to post. |
-u "test@liferay.com:learn" | Enter basic authentication credentials. |
Basic authentication is used here for demonstration purposes. For production, you should authorize users via OAuth2. See Using OAuth2 to Authorize Users for a sample React application using OAuth2.
The other cURL commands use similar JSON arguments.
Examine the Java Class
The Term_POST_ToInstance.java
class adds terms and conditions by calling the TermResource
service.
public static void main(String[] args) throws Exception {
TermResource.Builder builder = TermResource.builder();
TermResource termResource = builder.authentication(
"test@liferay.com", "learn"
).build();
System.out.println(
termResource.postTerm(
new Term() {
{
label = new HashMap<String, String>() {
{
put("en_US", "Foo");
}
};
name = "foo";
priority = 0D;
type = "payment-terms";
}
}));
}
This class invokes the REST service using only three lines of code:
Line (abbreviated) | Description |
---|---|
TermResource.Builder builder = ... | Get a Builder for generating an TermResource service instance. |
TermResource termResource = builder.authentication(...).build(); | Use basic authentication and generate an TermResource service instance. |
termResource.postTerm(...); | Call the termResource.postTerm method and pass the data to post. |
Note that the project includes the com.liferay.headless.commerce.admin.order.client.jar
file as a dependency. You can find client JAR dependency information for all REST applications in the API explorer in your installation at /o/api
(e.g., http://localhost:8080/o/api).
The main
method’s comment demonstrates running the class.
The remaining example Java classes call different TermResource
methods.
See TermResource for service details.
Below are examples of calling other Term
REST services using cURL and Java.
Get Terms from Instance
You can list all the terms and conditions from your Liferay instance with a cURL or Java command.
Terms_GET_FromInstance.sh
Command:
./Terms_GET_FromInstance.sh
Code:
curl \
"http://localhost:8080/o/headless-commerce-admin-order/v1.0/terms" \
--user "test@liferay.com:learn"
Terms_GET_FromInstance.java
Command:
java -classpath .:* Terms_GET_FromInstance
Code:
public static void main(String[] args) throws Exception {
TermResource.Builder builder = TermResource.builder();
TermResource termResource = builder.authentication(
"test@liferay.com", "learn"
).build();
System.out.println(
termResource.getTermsPage(null, null, Pagination.of(1, 2), null));
}
The instance’s Term
objects are listed in JSON.
Filtering, Paginating, Searching, and Sorting Terms
You can filter, paginate, search, and sort the returned terms and conditions. See the getTermsPage
method for more information. Use the priority
and type
fields to filter, search, and sort the results:
Filter Query | Description |
---|---|
type eq 'payment-terms' | The terms and conditions must be of type payment-terms |
priority eq 0 | The terms and conditions’ priority must equal 0 |
Sort Query | Description |
---|---|
priority:desc | Sort by priority in descending order. |
priority:desc,type:desc | Sort by priority in descending order first, then by type in descending order. |
Read API Query Parameters for more information.

TermResource termResource = builder.authentication(
"test@liferay.com", "learn"
).build();
termResource.deleteTerm(Long.valueOf(System.getProperty("termId")));
}
The API Explorer shows the Term
services and schemas and has an interface to test each service.
