getUpdated()

Syntax

Usage

Use getUpdated() for data replication applications to retrieve a set of IDs for objects of the specified object that have been created or updated within the specified timespan. The getUpdated() call retrieves an array of GetUpdatedResult objects containing the ID of each created or updated object and the date/time (Coordinated Universal Time (UTC) time zone) on which it was created or updated, respectively. Be sure to read Data Replication before using getUpdated() in your client application.

Rules and Guidelines

When replicating created and updated objects, consider the following rules and guidelines:

• The specified startDate must chronologically precede the specified endDate value. The specified startDate cannot be the same value as, or later than, the specified endDate value. Otherwise, the API returns an INVALID_REPLICATION_DATE error.
• Results are returned for no more than 30 days previous to the day the call is executed.
• Client applications typically poll for changed data periodically. For important polling considerations, see Polling for Changes.
• Your client application can replicate any objects to which it has sufficient permissions. For example, to replicate all data for your organization, your client application must be logged in with “View All Data” access rights to the specified object. Similarly, the objects must be within your sharing rules. For more information, see Factors that Affect Data Access.
• Certain objects cannot be replicated via the API. To replicate an object via the getUpdated() call, its object must be configured as replicateable (replicateable is true). To determine whether a given object can be replicated, your client application can invoke the describeSObjects() call on the object and inspect its replicateable property.
• Certain objects cannot be deleted, such as Group, User, Contract, or Product2 objects. However, if instances of these objects are no longer visible in the Salesforce user interface, they could have been rendered inactive so that only users with administrative access can see them. To determine whether a missing object instance has been made inactive, your client application can call getUpdated() and check the object’s active flag.
• Development tools differ in the way that they handle time data. Some development tools report the local time, while others report only the Coordinated Universal Time (UTC) time. To determine how your development tool handles time values, refer to its documentation.

Basic Steps for Replicating Updated Objects

Replicating objects involves these basic steps for each object that you want to replicate.

1. Optionally, the client application determines whether the structure of the object has changed since the last replication request, as described in Checking for Structural Changes in the Object.
2. Call getUpdated(), passing in the object and timespan for which to retrieve data.
3. Iterate through the returned array of IDs. For each ID element in the array, call retrieve() to obtain the latest information you want from the associated object. Your client application must then take the appropriate action on the local data, such as inserting new rows or updating existing ones with the latest information.
4. Optionally, the client application saves the request timestamp for future reference.

A client application likely performs other tasks associated with data replication operations. For example, if an opportunity were to become closed, a client application can run a new revenue report. Similarly, if a task is completed, the process can log this action somehow in another system.
