After your application detects a timeout or an error, it must next make a decision whether to retry the request or fall back to saved geocoding results.

Retry a Request

Retry your request a few times if timeouts are still being returned:

1. Retry the request
2. Wait 1 second and retry the request
3. Wait several seconds and retry the request

It’s important that you don’t retry so often that your attempts are mistaken as a denial-of-service attack. Limit your retries to 5 to 10 attempts to prevent a backlog of concurrent requests and allow system time to recover.

Some applications attempt to reuse HTTP connections. In the event that you experience a connection disruption, we suggest creating a completely new connection for the next attempt.

Fall back to saved geocoding results

Save geocoding results quarterly by running processing addresses or latitude/longitude coordinate pairs that cover your business needs (such as all new customer data received within the last 3 months). In the event of a timeout or other type of error, fall back to these saved results.

Things to consider when falling back to saved geocoding results:

• AFC Geo SaaS Pro Soap is updated on an off-quarter cycle. Map data and special tax jurisdictions are generally only updated during this quarterly release
• PCode and other characteristics of a location do not change often, if at all, once the data has been set
• Special tax jurisdictions may be added or removed from a primary jurisdiction during a quarterly release based on the local jurisdiction legislation
