Define an Action Link in a Template and Post with a Feed Element

Create an action link and action link group and instantiate the action link group from a template.

This example creates the same action link and action link group as the example Define an Action Link and Post with a Feed Element, but this example instantiates the action link group from a template.

Step 1: Create the Action Link Templates

From Setup, enter Action Link Templates in the Quick Find box, then select Action Link Templates.

Use these values in a new Action Link Group Template:

Field	Value
Name	Doc Example
Developer Name	Doc_Example
Category	Primary action
Executions Allowed	Once per User

Use these values in a new Action Link Template:

Field	Value
Action Link Group Template	Doc Example
Action Type	Api
Action URL	/services/data/{!Bindings.ApiVersion}/chatter/feed-elements
User Visibility	Everyone can see
HTTP Request Body	{ "subjectId":"{!Bindings.SubjectId}", "feedElementType":"FeedItem", "body":{ "messageSegments":[ { "type":"Text", "text":"{!Bindings.Text}" } ] } }
HTTP Headers	Content-Type: application/json
Position	0
Label Key	Post
HTTP Method	POST

Go back to the Action Link Group Template and select Published. Click Save.

Step 2: Instantiate the Action Link Group, Associate it with a Feed Item, and Post it

This example calls ConnectApi.ActionLinks.createActionLinkGroupDefinition(communityId, actionLinkGroup) to create an action link group definition.

It calls ConnectApi.ChatterFeeds.postFeedElement(communityId, feedElement) to associate the action link group with a feed item and post it.

// Get the action link group template Id.
ActionLinkGroupTemplate template = [SELECT Id FROM ActionLinkGroupTemplate WHERE DeveloperName='Doc_Example'];

// Add binding name-value pairs to a map.
// The names are defined in the action link template(s) associated with the action link group template.
// Get them from Setup UI or SOQL.
Map<String, String> bindingMap = new Map<String, String>();
bindingMap.put('ApiVersion', 'v33.0');
bindingMap.put('Text', 'This post was created by an API action link.');
bindingMap.put('SubjectId', 'me');

// Create ActionLinkTemplateBindingInput objects from the map elements.
List<ConnectApi.ActionLinkTemplateBindingInput> bindingInputs = new List<ConnectApi.ActionLinkTemplateBindingInput>();

for (String key : bindingMap.keySet()) {
    ConnectApi.ActionLinkTemplateBindingInput bindingInput = new ConnectApi.ActionLinkTemplateBindingInput();
    bindingInput.key = key;
    bindingInput.value = bindingMap.get(key);
    bindingInputs.add(bindingInput);
}

// Set the template Id and template binding values in the action link group definition.
ConnectApi.ActionLinkGroupDefinitionInput actionLinkGroupDefinitionInput = new ConnectApi.ActionLinkGroupDefinitionInput();
actionLinkGroupDefinitionInput.templateId = template.id;
actionLinkGroupDefinitionInput.templateBindings = bindingInputs;

// Instantiate the action link group definition.
ConnectApi.ActionLinkGroupDefinition actionLinkGroupDefinition =
 ConnectApi.ActionLinks.createActionLinkGroupDefinition(Network.getNetworkId(), actionLinkGroupDefinitionInput);

ConnectApi.FeedItemInput feedItemInput = new ConnectApi.FeedItemInput();
ConnectApi.FeedElementCapabilitiesInput feedElementCapabilitiesInput = new ConnectApi.FeedElementCapabilitiesInput();
ConnectApi.AssociatedActionsCapabilityInput associatedActionsCapabilityInput = new ConnectApi.AssociatedActionsCapabilityInput();
ConnectApi.MessageBodyInput messageBodyInput = new ConnectApi.MessageBodyInput();
ConnectApi.TextSegmentInput textSegmentInput = new ConnectApi.TextSegmentInput();

// Define the FeedItemInput object to pass to postFeedElement
feedItemInput.body = messageBodyInput;
feedItemInput.capabilities = feedElementCapabilitiesInput;
feedItemInput.subjectId = 'me';

// The MessageBodyInput object holds the text in the post
messageBodyInput.messageSegments = new List<ConnectApi.MessageSegmentInput>();

textSegmentInput.text = 'Click to post a feed item.';
messageBodyInput.messageSegments.add(textSegmentInput);


// The FeedElementCapabilitiesInput object holds the capabilities of the feed item.
// For this feed item, we define an associated actions capability to hold the action link group.
// The action link group ID is returned from the call to create the action link group definition. 
feedElementCapabilitiesInput.associatedActions = associatedActionsCapabilityInput;
associatedActionsCapabilityInput.actionLinkGroupIds = new List<String>();
associatedActionsCapabilityInput.actionLinkGroupIds.add(actionLinkGroupDefinition.id);

// Post the feed item. 
ConnectApi.FeedElement feedElement = ConnectApi.ChatterFeeds.postFeedElement(Network.getNetworkId(), feedItemInput);
