Call a method or use the ConnectApiHelper repository to post a feed element with an
already uploaded, inline image.
You can post rich-text feed elements with inline images and mentions two ways. Use the
ConnectApiHelper repository on GitHub to write a single line
of code, or use this example, which calls postFeedElement(communityId,
feedElement). In this example, the image file is existing content that has
already been uploaded to Salesforce as a content document (069). The post also includes text
and a
mention.
String communityId = null; String imageId = '069D00000001INA'; String mentionedUserId = '005D0000001QNpr'; String targetUserOrGroupOrRecordId = '005D0000001Gif0'; ConnectApi.FeedItemInput input = new ConnectApi.FeedItemInput(); input.subjectId = targetUserOrGroupOrRecordId; input.feedElementType = ConnectApi.FeedElementType.FeedItem; ConnectApi.MessageBodyInput messageInput = new ConnectApi.MessageBodyInput(); ConnectApi.TextSegmentInput textSegment; ConnectApi.MentionSegmentInput mentionSegment; ConnectApi.MarkupBeginSegmentInput markupBeginSegment; ConnectApi.MarkupEndSegmentInput markupEndSegment; ConnectApi.InlineImageSegmentInput inlineImageSegment; messageInput.messageSegments = new List<ConnectApi.MessageSegmentInput>(); markupBeginSegment = new ConnectApi.MarkupBeginSegmentInput(); markupBeginSegment.markupType = ConnectApi.MarkupType.Bold; messageInput.messageSegments.add(markupBeginSegment); textSegment = new ConnectApi.TextSegmentInput(); textSegment.text = 'Hello '; messageInput.messageSegments.add(textSegment); mentionSegment = new ConnectApi.MentionSegmentInput(); mentionSegment.id = mentionedUserId; messageInput.messageSegments.add(mentionSegment); textSegment = new ConnectApi.TextSegmentInput(); textSegment.text = '!'; messageInput.messageSegments.add(textSegment); markupEndSegment = new ConnectApi.MarkupEndSegmentInput(); markupEndSegment.markupType = ConnectApi.MarkupType.Bold; messageInput.messageSegments.add(markupEndSegment); inlineImageSegment = new ConnectApi.InlineImageSegmentInput(); inlineImageSegment.altText = 'image one'; inlineImageSegment.fileId = imageId; messageInput.messageSegments.add(inlineImageSegment); input.body = messageInput; ConnectApi.ChatterFeeds.postFeedElement(communityId, input);
