How to parse a JSON string for particular attribute

Hi @titan blazers,

Hope you are doing well,

To extract the attachment_url value from the JSON string in Apex, you can use the JSON.deserializeUntyped method to convert the JSON string into a map, and then traverse the map to access the desired attribute. Here's how you can do it:

String jsonString = '{ "ticket_cc_emails": [], "fr_escalated": false, "spam": false, "email_config_id": null, "group_id": 72000320936, "priority": 1, "requester_id": 72012786963, "responder_id": 72010582985, "source": 2, "status": 5, "subject": "Updated ACP Capacity", "id": 54942, "type": "SE Scheduler", "due_by": "2024-04-11T12:27:12Z", "fr_due_by": "2024-04-06T13:57:12Z", "is_escalated": false, "custom_fields": { "cf_class75953": "Configuration", "cf_subclass650579": "Availability", "cf_class832453": null, "cf_subclass605425": null, "cf_billing_subclass": null, "cf_test": null, "cf_connect_type": null, "cf_connect_subtype": null, "cf_subclass": null, "cf_priority": false }, "created_at": "2024-04-05T16:26:34Z", "updated_at": "2024-04-08T13:24:00Z", "tags": [ "SP Post Launch Adoption" ], "attachments": [ { "id": 72092546835, "content_type": "image/png", "size": 106213, "name": "Screenshot 2024-03-22 134756 (1).png", "attachment_url": "https://s3.amazonaws.com", "created_at": "2024-04-05T16:26:34Z", "updated_at": "2024-04-05T16:26:34Z" } ], "source_additional_info": null, "nr_due_by": null, "nr_escalated": false }';

// Deserialize the JSON string into a map

Map<String, Object> jsonMap = (Map<String, Object>) JSON.deserializeUntyped(jsonString);

// Extract the 'attachments' array from the map

List<Object> attachments = (List<Object>) jsonMap.get('attachments');

// Check if attachments exist

if (attachments != null && !attachments.isEmpty()) {

    // Extract the first attachment object

    Map<String, Object> attachment = (Map<String, Object>) attachments[0];

    // Extract the 'attachment_url' attribute from the attachment object

    String attachmentUrl = (String) attachment.get('attachment_url');

    // Print or use the attachment URL as needed

    System.debug('Attachment URL: ' + attachmentUrl);

} else {

    // Handle case where there are no attachments

    System.debug('No attachments found.');

}

This code snippet assumes that your JSON string has been stored in the jsonString variable. It first deserializes the JSON string into a map, then extracts the attachments array from the map. It checks if the attachments array is not null and not empty. If there are attachments, it extracts the first attachment object and then extracts the attachment_url attribute from it. Finally, it prints or uses the attachment URL as needed.

Hope this content will provide more understanding to you,

Thanks!
