Upcoming DCM/DFA Reporting and Trafficking API system maintenance

Tuesday, February 21, 2017

Starting in March, DoubleClick Campaign Manager (DCM) will be undergoing scheduled maintenance to make important updates to our systems. Every DCM account will be assigned a single maintenance window. However, these windows may be on different days for different accounts. More information about how this will affect the DCM product can be found in our help center. How will this affect API users?deleteinsertpatchupdateScheduled Maintenance pageWhat can API users do to prepare?If your application accesses multiple DCM accounts, you may be subject to multiple maintenance windows. If it's not possible to plan around these windows, you should prepare your application to catch and handle maintenance related errors. Recommended error handling strategies include:

For user initiated requests, return an error to the user along with instructions to wait up to 8 hours before retrying the request.

For server initiated requests, retry automatically using an exponential backoff strategy. For example: pause 30 seconds before the first retry, 1 minute before the second, 2 minutes before the third, and so on up to a maximum of 8 hours. This strategy helps ensure you're not calling the API too aggressively and that your request quota is not being wasted.
