Webhooks are an easy way to get notifications on events happening asynchronously within Lob's architecture. You can view, create, and debug webhooks on the Lob dashboard, as well as view subscribed events. Note that in Live mode, you can only have as many non-deleted webhooks as allotted in your current Print & Mail Edition. There is no limit in Test mode.
See our for more details on how to integrate.

National Change of Address (NCOA) is a service offered by the USPS, which allows individuals or businesses who have recently moved to have any mail forwarded from their previous address to their new address.
As a CASS-certified address verification provider, Lob also offers NCOA functionality to our Print & Mail customers. With the Lob NCOA feature enabled, postcards, self-mailers, letters, checks and addresses can automatically be corrected to reflect an individual's or business' new address in the case that they have moved (only if they have registered an NCOA with the USPS).
Event logs are records of the mail piece events associated to your account's API submissions.
While it is also possible to go to any resource type (postcards, letters, checks, etc.) in the left menu of the dashboard and export all selected tracking events in a CSV file, the Event Logs section is currently the only place where you can generate tracking events for return envelopes.
API logs are records of your requests, tied to the specific information you provided for the submission.
Use the filter to select a date range, reference ID, path, method, or status code which will generate a list of API logs that apply to the selected criteria. Click on any API log to view more details, including the request post body and response body.
We only save API logs for the preceding 30 days, as they are meant for simple real-time debugging.
For Enterprise edition accounts with NCOA enabled, Lob generates a weekly report of suppressed API response data for addresses that have been changed through NCOA. These reports can be downloaded in the dashboard under the . In order to gain access to and download NCOA'd data, customers must send at least 100 addresses within a single USPS-defined 'week' period.
